Lampworking: Glass tubes and rod are manipulated over a torch or in the olden days over an oil-fueled lamp. With this technique, you can work molten glass in a precise manor to create small or large works. Pictured here is Lloyd Moore working on a vacuum manifold.

Fused Glass: A process where pieces of glass are heated in a kiln to ranges 700C – 820C and they fuse together to become one. Depending on the temperature of the kiln you can create flat sheets of glass or glass in relief.

Cold-worked Glass: Working glass that is not hot. Cutting, grinding, engraving and sandblasting are some examples. To cut and grind glass to a polish is labor intensive but can give you unique optical qualities. Photo of Vladimir Klein working.

Neon: Hollow glass shapes are made to allow a vacuum to be pulled and then are filled with one of the Nobel Gases such as Neon. Depending on the color of the glass and the gas to fill the piece you have a wide range of colors and effects.

Furnace Glass: Glass made with molten glass taken out of a furnace. Furnaces are designed to hold glass in pots at a molten state. This gives the glassblower a place to gather glass from that then can then shaped and formed. Reheating the glass to keep it in a molten state while forming is necessary.

Painting on Glass: an ancient tradition of using glass powder enamels to paint on glass. After painting, the item must be fired again to fuse the enamels to the glass.
