What kind of glass is used for glass blowing?

The two most common types of glass used in glassworking today are borosilicate, or “hard” glass and soda-lime or “soft” glass. Each are readily available at online retailers and have their own pros and cons when used for glassblowing, lampworking and other glass art techniques.

The term lampworking originated from when Venetian glassworkers used an oil lamp to heat their glass over. Flameworking is a more modern take on the term. Present-day glass artists primarily work with an oxygen-propane torch.

What is mirror in torch?

Concave mirror
Concave mirror is used as torch reflector.

What is high borosilicate glass?

Borosilicate glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. Its durability has made it the glass of choice for high-end restaurants, laboratories and wineries.

How can you tell if glass is borosilicate?

Eyeball It. If you have a dish at home that you want to test you can also try just looking at the hue. If you look at the edge of a dish and it is made out of soda-lime glass it will be a blueish-green hue. If the glass is Borosilicate then you should not see any color.

Can I melt glass with a propane torch?

A kiln is necessary to raise the temperature of glass to 1400 to 1600 degrees, while a blow torch can raise the temperature of glass to approximately 900 degrees. Ignite the flame on your propane blow torch. Position the blue portion of the flame on the glass. The glass will become pliable and begin to melt.

What is Lampworking vs glassblowing?

Lampworking is a type of glasswork in which a torch or lamp is used to melt the glass. Once in a molten state, the glass is formed by blowing and shaping with tools and hand movements. Lampworking differs from glassblowing in that glassblowing uses a furnace as the primary heat source, although torches are also used.

How did Glass Alchemy change the way we work?

The scientific glass blowing techniques that developed since then, combined with the artistic approach from the soft glass world, helped create a whole new approach to glass blowing, using a high temperature torch. Since the creation of the Glass Alchemy color palette, we have seen an explosion in modern lampworking over the past 20 years.

How is glass formed in a flameworking lamp?

Once in a molten state, the glass is formed by blowing and shaping with tools and hand movements. It is also known as flameworking or torchworking, as the modern practice no longer uses oil-fueled lamps.
