What is glassblowing? It is the process of making hollow vessels and sculptural objects out of hot liquid glass. Glassblowing was invented thousands of years ago, and must be done by a skilled artisan. Glassblowing is also knows as off hand glass blowing or furnace glass blowing. Glass rapidly cools, so after approximately 40 seconds of manipulation, the glass must be reheated in a heating chamber called the glory hole. Additional pieces of hot glass can be added to form handles, stems and other sculptural elements.
Flameworking, or lampworking is the process of heating small glass rods in the flame of a small torch to make beads, pendants, and other small objects. Soft glass is commonly used for bead making,while borosilicate is mainly used for small objects, such as drinking glasses.
