Accepted Answer

We select high-quality raw materials in strict accordance with international and industry production standards. All incoming materials are tested in our laboratory to eliminate batches with excessive heavy metals or radiation, ensuring that only qualified raw materials are used in production.

Question 5

How do you control the quality of raw materials upon arrival?

Accepted Answer

We perform laboratory chemical analysis on each batch of raw materials like quartz sand and dolomite. Any batch that exceeds national or industry standards will be rejected, ensuring that unqualified materials are not accepted into storage.

Question 6

What raw materials do you use in your daily production of glass tumblers?

Accepted Answer

Our main raw materials include quartz sand (providing silica), soda ash (providing sodium oxide), calcite (providing calcium oxide), dolomite (providing magnesium oxide), feldspar (providing aluminum oxide), and broken glass (cullet). In addition, there are auxiliary materials such as refining agents and colorants.

Question 7

Why is quartz sand  the most important raw material for glass production?

Accepted Answer

Silica from quartz sand serves as the skeleton of glass, accounting for approximately 70% of the glass composition. It determines the glass’s chemical stability, mechanical strength, and heat resistance.

Question 8

What role does soda ash play in glass production?

Accepted Answer

As a fluxing agent, soda ash (sodium carbonate) lowers the melting temperature of quartz sand, saves energy, and provides good fluidity to the molten glass.

Question 9

How do you select your quartz sand suppliers?

Accepted Answer

We give priority to suppliers with stable mines, advanced processing technology, uniform particle size, and low iron content. We also require third-party composition test reports and conduct on-site inspections.

Question 10

What is lead-free crystal? Does it really contain absolutely no lead?

Accepted Answer

Lead-free crystal means that no lead oxide is intentionally added; instead, alternatives such as potassium oxide, barium oxide, zinc oxide, and titanium oxide are used. However, “lead-free” does not mean zero lead content. Due to natural impurities in raw materials, trace amounts of lead may still be present, but these levels are below international and industry standards.

Question 11

What are the main steps to make a glass cup?

Accepted Answer

Great question! Here’s how a glass goblet goes from raw materials to finished product:1.Mixing – Raw materials are carefully blended.2.Melting – The mix is melted at high temperatures.3.Forming – Shaped by pressing, blowing, or spinning.4.Annealing – Slowly cooled to remove internal stress.5.Cold finishing – Cut, ground, and polished.

Question 12

What's the difference between machine-blown and machine-pressed glasses?

Accepted Answer

1.Machine-blown glasses are made by blowing compressed air into a mould. This method is typically used for wine glasses and taller, deeper styles. They're known for being thin-walled and having a smooth, polished finish.2.Machine-pressed glasses are made by pressing the glass into a mould with a ram. This is common for thick-bottomed tumblers and beer glasses. They're valued for their precise dimensions and durable, sturdy base.

Question 13

When are the patterns on the glasses made?

Accepted Answer

The patterns—like diamond or hammered designs—are actually built into the mould itself, so they're formed in one go during the shaping process. Nice and simple!Let us know if you'd like to know more about any specific finish.

Question 14

What material are your glass cups made of?

Accepted Answer

We mainly offer two types:Soda-lime glass: This is our standard, everyday material. It's durable, cost-effective, and perfect for daily use like water tumblers or beer glasses.Lead-free crystal: This is our premium option. It's much clearer, more reflective, and gives that nice "ping" when tapped. It's ideal for wine or champagne glasses and is completely safe for food contact.Do you have a specific style in mind? Let me know and I can confirm the material for you.

Question 15

What's the best value-for-money glass material for hotel or restaurant wine glass purchases?

Accepted Answer

Our suggestion:For public areas like bars and dining rooms, go with soda-lime glass. It's tougher and more budget-friendly — perfect for high-traffic use.For guest rooms or high-end dining, lead-free crystal is a great choice.Let me know if you have a specific style in mind.

Question 16

What are the common sizes for your Goblet?

Accepted Answer

Our wine glasses typically range from 350ml to 500ml, and Champagne flutes are usually 150ml to 200ml. You'll find the exact specs on each product page.Let me know if you're looking for a specific size!

Question 17

Are your crystal glasses lead-free?

Accepted Answer

Yes, our crystal glasses are made from lead-free crystal glass and meet international food safety standards, so they're perfectly safe to use in restaurants or guest rooms.

Question 18

I see crystal glasses are more expensive than soda-lime ones — are they more durable?

Accepted Answer

Crystal glasses do cost a bit more, mainly because they offer better clarity and a nicer feel in the hand.In terms of durability, here's the difference: crystal glass is harder and more scratch-resistant, but it's also a bit more brittle — so it doesn't handle knocks as well as soda-lime glass. Soda-lime glass is tougher and more impact-resistant, making it a solid choice for busy restaurants and everyday use.So in short: go for crystal when you want that premium look and feel; choose soda-lime if durability and value are your top priorities.

Question 19

What makes crystal glasses better?

Accepted Answer

The main advantage of crystal glass is its clarity and feel. It allows for thinner, lighter walls and has a beautiful sparkle that really stands out.Plus, when you gently clink them, crystal glasses give off that lovely ringing sound — perfect for weddings, fine dining, or corporate events where you want to add a touch of elegance.Are you looking at a specific occasion? Happy to help you choose!

Question 20

What are wine glasses, Champagne flutes, and beer glasses mainly made of?

Accepted Answer

They're all made from food-grade glass, but there are two main types we use:One is soda-lime glass – it's durable, cost-effective, and what we use for most beer glasses and everyday tumblers.The other is crystal glass (lead-free) – it's clearer and has more sparkle, which is why we use it for premium wine and Champagne glasses.So , it comes down to what the glass is for – we match the material to the drink and the occasion.Let me know if you have a specific style in mind – happy to help you choose.

Question 21

Do your glass cups contain heavy metals like lead or cadmium? Are they safe?

Accepted Answer

Rest assured, all our glass cups are made from food-grade, lead-free glass .Whether it's our everyday soda-lime glasses or premium lead-free crystal, comply with international food safety standards . so your guests can enjoy them with complete peace of mind.

Question 22

What types of beer glasses do you have? Which beers are they for?

Accepted Answer

Great question! We've got a few styles to suit different beers:American pint glasses: Classic straight-sided design,Very popular in pubs and restaurants.German weizen glasses: Tall and tapered, designed to capture the fruity aromas and bubbly head of wheat beers.Beer mugs with handles:  sturdy with a comfortable grip – ideal for casual drinking.Capacities range from 200ml to 1000ml, so you can pick what suits your venue and your customers' drinking style best. Want me to recommend a few of our bestsellers?

Question 23

How are tempered glass cups made? What makes them better than regular ones?

Accepted Answer

Great question ! Tempered glasses start out as regular cups, then go through a special tempering furnace where they're heated up and rapidly cooled. Think of it like a "strengthening treatment" for glass.This creates a protective stress layer on the surface, which makes a big difference Much stronger and  last longer.

Question 24

Are your glasses handmade or machine-made?

Accepted Answer

Most of our range is machine-blown, which gives us consistent sizing, stable supply, and better value for money — ideal for hotels and restaurants buying in larger quantities.That said, we do offer a small selection of hand-blown pieces.

Question 25

Do the glasses ever warp after shaping? How do you keep them so uniform?

Accepted Answer

When glasses are first shaped, they're actually still soft and can easily lose shape. That's why our equipment quickly transfers them into the annealing furnace — think of it as giving them a stable place to cool down and set properly.

Question 26

Why are crystal glasses so much more expensive than regular ones? What makes them cost more?

Accepted Answer

There are a few reasons crystal glasses cost more:First, the raw materials. To get that brilliant clarity and sparkle, crystal uses special ingredients (like potassium or barium oxide — we use lead-free formulas these days). These materials are simply more expensive than standard glass ingredients.Second, the manufacturing process. Crystal melts at higher temperatures and is trickier to shape, which means more rejects along the way. The yield rate is lower compared to regular soda-lime glass — and that adds to the cost.

Question 27

Are the bowl and stem of a wine glass made in one piece, or are they joined together afterwards?

Accepted Answer

Actually, both methods are used:Some glasses are one-piece moulded — the bowl and stem come out of the mould together, which gives them good overall strength.Others are heat-joined — the bowl and base are made separately, then fused together at high temperatures.

Question 28

I'm a hotel buyer — what kind of water glasses would you recommend for guest rooms?

Accepted Answer

For guest rooms, we usually recommend tumblers — the ones without stems.Here's why: they've got a good medium thickness so they're not too fragile, the high clarity makes them look clean and fresh to guests, and the simple design (no complicated patterns) makes washing and sanitising much easier.

Question 29

How clear are your wine glasses? Do they have that greenish tint?

Accepted Answer

Our stemmed glasses are made of soda-lime glass. By precisely controlling the iron content in the raw materials, we effectively reduce the greenish tint of the glass and meet the high-definition clear glass standard.

Question 30

What's the difference between machine-pressed and hand-blown glasses? Which one is better?

Accepted Answer

They're quite different — it really depends on what you're after:Machine-pressed glasses:1.Great for thicker, angled shapes like tumblers2.Consistent size and shape — every piece is identical3.Good value for money4.May have slight mould seamsHand-blown glasses:1.Ideal for wine glasses or unique shapes — thinner, lighter walls2.Each piece has subtle differences — more character and an artisanal feel3.Lower production volume, so higher price point4.Beautiful to hold — perfect for premium settings

Question 31

What is the glass annealing process and why is it important?

Accepted Answer

Annealing is a process that puts formed glass products into an annealing furnace and cools them slowly under precisely controlled temperature.It is mainly used to eliminate the internal stress generated in the glass due to rapid cooling. Glass without proper annealing will be very fragile and break easily with slight collision or temperature change.

Question 32

Why do crystal glasses make that lovely ringing sound when they clink, while regular ones don't?

Accepted Answer

Crystal glass is denser and harder than regular glass, so sound travels through it faster and vibrates at a higher frequency. Think tapping a nice piece of metal versus tapping wood.Plus, crystal glasses have thinner walls, so they resonate easily. A gentle clink gives you that beautiful, long-lasting "ding" that lingers — toasts and celebrations.

Question 33

I often hear the term "inorganic chemicals within safe limits" — what does that actually mean? Which substances are we talking about?

Accepted Answer

Specifically, we test for several categories:First, harmful heavy metals — like lead, cadmium, arsenic, antimony, mercury, chromium, and barium. These must all be within safe limits.Second, non-metal substances — such as fluorides and chlorides.Third, other metal elements — including boron, zinc, copper, and nickel — also need to stay within approved ranges.All this testing ensures the glass is safe for everyday use — whether you're serving hot coffee, ice water, or even acidic juices. Nothing unwanted migrates into the drink.

Question 34

Are these glasses safe? No harmful stuff in the materials?

Accepted Answer

Rest assured, they're  safe. We use  food-grade natural minerals that are carefully selected, and every batch is tested to make sure things like lead and cadmium are well within safe limits — so there's absolutely no risk to health.

Question 35

I've heard some stone materials have radiation — glass is made from minerals too, so is that a concern?

Accepted Answer

I  understand the concern ,no need to worry .The minerals used in glass — things like silica sand, soda ash, and limestone — are different from building stones that sometimes raise concerns. They're common, naturally occurring materials that don't contain radioactive elements.

Question 36

Will long-term use of your glass cups affect the health of guests and staff?

Accepted Answer

No concerns at all. Our glass cups are made of food-grade glass, which meets the same safety standards as regular tableware sold in supermarkets. Many partner hotels have used them for years without any health-related issues.

Question 37

For everyday restaurant use, would you recommend tumblers or stemware?

Accepted Answer

It mainly depends on your usage scenario. Tumblers, such as water glasses and juice glasses, are stable and not easy to tip over, making them very suitable for cafeterias or fast-paced daily catering services. Stemmed glasses are mainly used for the formal service of wine and cocktails.

Question 38

Are your crystal glasses made from real crystal? Are they heavy?

Accepted Answer

we say "crystal glasses", we don't mean carved from natural gemstones. They're actually a high-quality type of glass called "crystal glass".The biggest advantages of this glass are its brilliant clarity, beautiful sparkle, and a clear, ringing sound when tapped lightly. While the material itself is quite dense, our craftsmen intentionally make the walls of the glasses thinner during production.

Question 39

Is there any risk of lead poisoning from your crystal glasses?

Accepted Answer

Rest assured, the crystal glasses we recommend are lead-free crystal, so they're completely safe and non-toxic — no lead, no worries.

Question 40

Why are some glasses heavier than others even when they hold the same amount?

Accepted Answer

It usually comes down to the material and design:Heavier glasses are typically soda-lime glass or have a thicker build — they're more durable and built to last, perfect for high-use settings.Lighter glasses are often crystal or thin-walled designs — they prioritise a finer drinking experience and maximum clarity.

Question 41

Which is better — those tall, skinny champagne glasses or the shallow ones?

Accepted Answer

They're both good — just for different things:The tall, skinny ones are flutes. You get to watch the bubbles stream up from the bottom — perfect for weddings, toasts, celebrations. Looks the part.The shallow ones are coupes. Wide bowl, nice and stable for stacking champagne towers, and they've got that vintage vibe — also great for cocktails.So no right or wrong — just depends what you're using them for. Toasts and bubbles? Go flutes. Towers or cocktails? Coupes are your pick.

Question 42

How clear are your wine glasses? Can you actually see the colour of the wine?

Accepted Answer

Most of our wine glasses are made from high‑clarity glass, so they're nice and see‑through. Once you pour the wine, the colour shows up beautifully — no cloudiness, nothing dull.

Question 43

Why is there sometimes a faint line on the glass stem? Is it a defect?

Accepted Answer

That line is called a mould seam — it's a natural trace left where the two halves of the mould come together during production.

Question 44

Do you allow minor scratches on the glass surface?

Accepted Answer

We follow strict quality standards. Before packing, every piece is checked under bright light. Obvious scratches aren't acceptable. Very fine hairline marks—hard to spot under normal lighting—are generally considered acceptable.Let me know if you have any other questions.

Question 45

Can you spot things like dust or bits inside the glasses?

Accepted Answer

Of course, and we're pretty thorough about it. Before packing, every single glass goes under a bright light inspection. Our quality team checks both the inside and outside carefully — even tiny bits of dust or glass particles are easy to spot under the light. So you can be sure that every glass we ship is clean inside and out as possible.

Question 46

I noticed the rim isn't perfectly round — is that a defect?

Accepted Answer

It depends on the making process.For machine-made glasses, the rim should be nice and round.For hand-blown glasses, a very slight oval shape is actually quite normal. You'd barely notice it, and it doesn't affect how the glass feels or performs. It's just a natural trace of the handmade process — proof that it's genuinely hand-crafted.

Question 47

There's a mark like a "water stain" inside the glass — what is it? Is it a defect?

Accepted Answer

That "water stain" is actually a slight flow mark left during cooling when surface tension changes — think of it like a ripple mark from when the glass was still soft.Safety-wise, it's completely harmless — doesn't affect how the glass performs or the taste of drinks.

Question 48

I can see fine lines on the glass, almost like wavy patterns — what causes that? Is it a defect?

Accepted Answer

Those fine lines usually come from one of two things:One is mould seams — very fine lines where the mould comes together on machine-made glasses. As long as they're not rough to the touch, they're completely normal and don't affect how the glass performs.The other is wavy patterns — more common in handmade glasses. They happen naturally as the glass flows during shaping, a bit like gentle ripples on water. Some people actually like them — they add texture and catch the light in a nice way.During our inspection, only glasses that feel rough to the touch or have very obvious lines are rejected as unqualified. Very subtle ripples or lines are within normal range, so you can use them.

Question 49

Why are there black or white spots on the bottom of my glass?

Accepted Answer

These are bubbles or sediments formed during the melting of glass raw materials. They are common glass imperfections and usually do not affect safety. Our products all go through strict inspection before packaging, so such spots rarely appear.

Question 50

There are small bubbles in the glass — can I still use it? Is it a defective product?

Accepted Answer

No worries at all — it's perfectly fine to use. Tiny bubbles can occasionally appear during glassmaking. They're just a natural characteristic of the material and don't affect safety or the taste of drinks.Our quality standard is: as long as the bubbles aren't on the rim (so they don't affect the feel when drinking) and aren't right in the middle of a decorative surface, they're considered acceptable.

Question 51

After washing, my glasses have a cloudy white film that won't wipe off — what's going on?

Accepted Answer

This is actually pretty common, and it's usually not the glass's fault!It's likely due to hard water — if your local water has high mineral content, those minerals can be left behind as water evaporates, forming those white marks or cloudy spots, especially when air-dried.Easy fix: try rinsing with filtered or softened water, and you'll see fewer marks. For existing spots, a quick wipe with a bit of white vinegar or lemon juice brings back the sparkle!Nothing to worry about — the glass itself is perfectly fine.

Question 52

How do you make sure every glass that leaves your factory is good? Can you catch defective ones before shipping?

Accepted Answer

We have a three-step inspection process to make sure every glass is properly checked:First, automated optical scanning — machines scan each glass at high speed, rejecting any with bubbles, stones, or cracks right away.Second, manual light inspection — our quality team checks every single glass under bright light for any surface imperfections.Third, pre-pack sampling — we randomly pick samples to double-check size, capacity, and overall consistency.With these three layers, any defective glasses get caught long before they're packed. The ones that make it to you? They've passed all the checks. Rest assured!

Question 53

Are the slight vertical streaks on the cup body defects?

Accepted Answer

Not necessarily. For machine-pressed glass cups, the slight and uniform vertical streaks on the cup body are process traces formed by the production mold, not defects.

Question 54

There are very fine vertical lines on the glass, but I can't feel them with my finger — is that a defect?

Accepted Answer

It depends! If the vertical lines are very faint and evenly spaced, and you can't feel them at all, then it's usually not a defect.Two possibilities here:One is that they're decorative lines from the mould — some machine-pressed glasses have these designed in, either for grip or style.The other is that they're just minor production marks — as long as they're not obvious or rough to the touch, they're perfectly acceptable.

Question 55

What do you check in the final inspection before packing and shipping?

Accepted Answer

Before packing, we check every single glass carefully:Rim — smooth and comfortable, nothing rough;Inside and outside — no scratches, stains, or dirt;Base — sits flat on the table, no wobble;Clarity — nice and clear, no cloudiness;Pattern (if any) — sharp print, no fading or misalignment;

Question 56

With so many glasses to inspect, how do you make sure none slip through?

Accepted Answer

Great question — this is key to quality control! We prevent missed defects in two main ways:First, job rotation — our inspectors don't stare at the same thing all day. We rotate them regularly so their eyes stay fresh.Second, controlled inspection pace — we set a reasonable speed.  Every piece gets the time it needs to be checked properly.On top of that, we do random spot checks before packing — just to double-check everything's good.

Question 57

Sometimes after washing and drying, my glasses have white marks that won't wipe off. Why?

Accepted Answer

This is pretty common, and it's usually not the glass's fault!Those white marks are mineral deposits (mainly calcium and magnesium) left behind when water evaporates. If you're in a hard water area, you'll see this more often.

Question 58

Can your glasses be used for serving chilled champagne？ Will they crack in the cold？

Accepted Answer

Absolutely! Cold temperatures alone won’t make our glasses brittle or prone to breaking. They’re perfectly safe for serving chilled champagne or wine, and even for sitting in an ice bucket — no worries at all.One thing to keep in mind: glass is more sensitive to sudden temperature changes than to the cold itself. For example, taking a glass straight from the freezer and immediately pouring in boiling hot liquid — that quick shock is what causes issues.So as long as you avoid those extreme temperature swings, normal chilled serving is completely safe.

Question 59

Do your glasses have any rough spots or chips on the rim? How do you check for that?/ How do you check for burrs or chips on the rim of the glass?

Accepted Answer

Great question – the rim is the most important part for us, because it goes right against your lips. Comfort matters most.We do a double check:First, by touch – our inspectors run their finger gently around the rim. Any tiny burr or uneven spot, you’ll feel it.Second, by sight – we use reflected light to look for chips, nicks, or rough edges.Every glass goes through strict inspection – especially the rim. So we can say with confidence: you won’t get a glass with a dodgy rim from us.

Question 60

Do you ever get bubbles or bits in the join between the bowl and the stem on your stemware?

Accepted Answer

Great spotting! That join is actually heat-fused, so it can be one of the trickier spots in production — bubbles do occasionally form there.That’s exactly why our inspectors pay extra attention to this area. If we spot any noticeable bubbles or tiny particles (what we call "stones"), that glass gets rejected on the spot — no exceptions.So rest assured: every piece that makes it to you has had that join checked and cleared. Clean, solid, and ready to serve.

Question 61

Why is there a line on the glass? Do all glasses have it?

Accepted Answer

Good question! That line's called a mould seam — it's a natural mark left where the two halves of the mould come together when the glass is machine-blown.Most machine-made glasses have it to some degree. Here's the deal:If you can barely see it and it feels smooth to the touch, that's totally normal — doesn't affect how the glass performs at all.If it feels rough or scratchy, that's a quality issue — and we'd knock it out during inspection.

Question 62

Is the rim smooth to touch? Could it cut my lips when I'm drinking?

Accepted Answer

Honestly, the rim's one of the first things we look at. It's what your guests actually drink from, so it's got to feel good.Every glass goes through a finishing process — either fire-polished or ground down — to make sure the rim's nice and smooth, no roughness at all.Before they're packed, our team runs  every single one. If it catches at all, it's out.

Question 63

Are the glasses clean when you pack them? No fingerprints or dust?

Accepted Answer

Rest assured, every glass gets a careful wipe-down with a clean, soft cloth after inspection before we pack it.

Question 64

The glasses smell a bit when I open the box — is something wrong?

Accepted Answer

Yeah, that can happen sometimes – but don’t worry. The glass itself doesn’t have any smell. It’s usually just the box or the foam packaging, especially if it’s been sealed up for a while.
