Glossary / Sculpting Tools

Sculpting tools

Rods with steel balls and other shaped ends, for pushing and modelling glass, including from inside a bubble.

What it is

These are steel rods ending in a ball or other shape. Jasen Johnsen’s inside sculpting tools are 5/16” stainless rods with solid steel balls,⁠⁠[1] and Carlo Donà makes sculpting tools with balls from 5 mm to 50 mm.⁠⁠[2]

How it’s used

Inside sculpting tools are for “sculpting from the inside of a bubble and pushing material out”.⁠⁠[1]

History

Carlo Donà’s family foundry opened in Murano in 1923 making tools for Venetian glassworkers, and the craft has passed through four generations of blacksmiths.⁠⁠[2]
