How to Melt A Glass?

[gladss]

Hi everyone,

Can someone tell me how to melt a glass?

What equipments are needed?

After it's melt, I would like to cast it.

How to release the glass from its cast so that it will not broken and shattered?

Thank you

I am new to the hobby and you sound like your trying to get into glass working, is this the case?

You need a torch and a kiln along with a bunch of other stuff but these are the two major pieces equipment.

Wrong type of glass work my foreign friend.

erm, Welcome to The Melting Pot.

are you trying to melt "a glass" as in some form of drinking glass

or are you trying to melt glass in general?

I'm suspecting English is not your first language? Where you from?

Assuming you're not some spam bot and really interested in glass I would suggest you kinda lurk and browse the site for a few days, watch some YouTube videos, do some of your own research.

In short, to answer the question of what you need for melting and casting glass (a subject that's not a primary focus of THIS particular forum) you'll need a kiln, mold making material, and a lot of trial and error, but some good books wouldn't hurt. Boyce Lundstum has a good book if I recall correctly? Kiln casting of glass isn't really a beginners project per se, but if it's what you're interested in I would get with someone who has a kiln able to go to 2000ºF or higher, and start with some open faced molds made of plaster or gypsum mixed with silica flour...those tend to be the easiest molds.

Yes I would like to melt a clear, transparent drinking glass.

After that, I would to change its shape into another.

Will it be melted by using torch?

Where I can buy the cheap, good torch online?

I would like to know too how the clear, transparent glass is made?

What materials and what equipments are needed?

What are the step of processes?

I am not full of information right now as I am new to the hobby, but I have watched hours of video on youtube and learned a lot from just that alone.

You can melt glass several ways, but the way that is most affordable and to do what you want would be a lamp working torch.

Depending on your country is where you would buy your torch online or locally.

Where are you based from?

Do a google search on "Glass Compatibility COE" this is key to know before ORDERING OR WORKING with any glass.

This forum is full of information and warm members willing to help, just have to ask the right questions.

^Bad advice. You point a torch at a drinking glass and it'll explode like a grenade. Doug was right. The only way to go about this is in a kiln. And it's not easy. Google that shit.

gladss, send a PM to a member named Funksizzle. he'll give you all the info you need to do what you're trying to do, and more.

We're international bay-bee!

Casting isn't so hard, but commercial soft glass like found in bottles and tumblers can be tough to work with. You can rarely combine it because of COE differences and often the stuff will divitrify pretty badly when you try.

But, if you're determined to try it anyway (I've mucked about with wine bottle glass before)....

Like Greymatter said, you'll need a kiln and fusing for soft glass tends to run around 1500 degrees. Keeping it liquid for any long period of time takes about 2000.

But say you want to cast in the kiln, you'd need a mold (plaster and silica's cheapest; wear a n-100 respirator), I'd suggest crushing it down into small size cullet (again with the respirator) place it in the mold, run it up to 1500, bada boom bada bing, you'll get a shaped puddle of glass that likely will look scummy because of devit.

There's a lot more to it to avoid that involving different places where you want to hold temperatures to get bubbles out, times when you want to crash the temps fast to avoid devit, and variances in the high temp based on the glass, but that's what experimenting is for.

You might join and search around warmglass.com for a bit, they're fusers/casters over there. This forum tends to be heavy on the borosilicate.

And if you're just looking to wreck some glass and a microwave, try this: http://www.youtube.com/watch?v=Jj2u2n_o7Cw

There are several method of melting glass. But it needs some kind of necessary equipment such as kiln or blowtorch. The glass can be melt with the blowing. The selection of melting procedure mainly depends on reason of melting as if making jewelry than high cost procedure are required.

[gladss]

What fuel is used for the torch and kiln?

[truedef]

Torch is powered by oxygen and propane usually. You can use oxygen and natural gas but propane burns hotter.

Kilns normally run off power but you can get gas powered kilns as well.

Hi,

You still didn´t make it clear what you wanna do.
Do you wanna melt a goblet and make another one or do you for example wanna make a figurine from it?
Why do you wanna use an old goblet ?
I think,you´re still a bit lazy to check the many recources of knowledge as there are thousands of
vids in the net.

If you seriousley wanna do something with hot glass,it will for sure take you more than just a thread here.
You will NOT be anle to do what you want to do in short time and for a few bucks.
Why don.t you give an answer to where you come from?

just wondering,
Axel

This thread is hilarious.

[Greymatter Glass]

I think either:

a) gladss is someone from the forum trolling us and this thread got boring because it didn't get the reaction the poster expected.

or,

b) gladss realized they're in way over their head, and is probably gone for now.

I am trying to use bottle glass cullet for melting in my furnace. By the time I reach 1850 F, the glass bubbles puffs up like milk boiling over and fouls my linings. The puffing happens quickly at around 1820 and doesn't stop even if I reduce the temp down to 1450 F.
How can I get rid of these bubbles and puffing up of the melt. I need to take the temp to 2200 but unable to, because of this puffing up of "curd".
Help??!!!

Yet another hilarious post. Take your rabid dog to the vet to get put down, it's a danger to society.

Troll Attempt 2/10

This is not a furnace glass forum, but I can tell you bottle glass SUCKS for offhand blowing. Try Craftweb or the GAS forums.

Lol easy on the referrals please but yes the gas forums will answer all your questions.
