Traditions Hand Craft Gallery carries artists that work in Blown Glass and Fused Glass including recycled fused glass.
Blown Glass is a process where molten glass is gathered on a hollow steel pipe like honey, shaped, blown, and reheated to form an object. When casting glass, clear molten glass is ladled into impressions made in moist sand. All glass is put into an annealing oven after it is made to bring it to room temperature slowly, so it does not crack.
Fused Glass methods involve stacking, or layering thin sheets of glass, often using different colors to create patterns or simple images. The stack is then placed inside the kiln (which is almost always electric, but can be heated by gas or wood) and then heated through a series of ramps (rapid heating cycles) and soaks (holding the temperature at a specific point) until the separate pieces begin to bond together. The longer the kiln is held at the maximum temperature, the more thoroughly the stack will fuse, eventually softening and rounding the edges of the original shape. Once the desired effect has been achieved at the maximum desired temperature, the kiln temperature will be brought down quickly through the temperature ranges to avoid devitrification. The glass is then allowed to cool slowly over a specified time, soaking at specified temperature ranges which are essential to the annealing process. This prevents uneven cooling and breakage and produces a strong finished product.
