Soda-lime Borosilicate Lead crystal

Compatibility assumes the tool is rated for the working temperature of that glass family. Check the maker's documentation before use.

Overview

A wooden block is the oldest shaping tool in the shop. It is kept soaking wet, and when it touches hot glass the water flashes to steam and forms a cushioning layer that stops the wood from burning. That steam layer also chills the surface of the glass, which stiffens it and helps a gather hold its shape while you work the rest of the piece.

Safety notes
  • Never use a dry block. Dry wood chars, smokes and grips the glass instead of shaping it.
  • The steam released is scalding. Keep the block below the level of your face.

Using it well

Practical guidance
  • Keep two blocks so one is always fully soaked.
  • A block with a carved hollow shapes a rounded form faster than a flat one.
  • Use light, rolling contact rather than pressing. The block shapes by chilling, not by force.

What to look for

  • Dense fruitwood that resists charring
  • Carved bowl on one face for rounded forms
  • Handle drilled for a lanyard so it stays in the water bucket
