In the practice of glassblowing, several specialized tools are essential for manipulating molten glass into decorative or functional forms:

Blowpipe: A hollow metal tube used to gather, inflate, and shape the molten glass.1
Pontil: A solid metal rod tipped with molten glass, used to attach to the bottom of a piece for finishing.1
Marver: A flat, smooth surface, typically made of metal, used for rolling and shaping the molten glass.1
Shears and Tweezers: Hand tools used to cut and manipulate the glass while it remains soft.1
Gaffer’s Chair: A bench featuring two extended arms; the blowpipe is trundled along these arms to maintain the symmetry of the glass.1

Additionally, safety equipment such as heat-resistant gloves and goggles is required to protect the artisan while working with the furnace, which melts glass at approximately 1,093 °C (2,000 °F).1
