Quick Tip: Circles From Squares

Pile of Cabochons

Create round cabochons from squares by using the 6 mm rule!

The Stack

Top (6 mm): A “lensing” layer of Clear. This layer will stretch considerably.

Middle (3–4 mm): This “design” layer will stretch and be visible through the top layer. Use part sheets or pieces of 3 mm sheet glass.

Bottom (6 mm): Typically not visible from the front. This layer will stretch the least.

  • 6 mm Tekta Clear is a natural for this project. It’s more efficient, with fewer pieces to cut, clean and assemble! Measure and score a grid of 0.75˝ squares, then run them using the Rule of Halves. Two layers of 3mm will also work.
  • A dab of GlasTac Gel (008269 & 008268)will keep the stack together before firing.
  • The stacks flow out to about 1.25˝ (32 mm) in diameter, so give them room.
  • For the cleanest release, we recommend firing on ThinFire.
Design Possibilities
  • Blue/Vanilla Part Sheet: Scatter Steel Blue Opalescent Coarse Frit (000146-0003) onto a base of 3mm Clear sheet glass, then sift a heavy layer of French Vanilla Powder (000137-0008) over the top to cover. Fire to a full fuse. Maximize depth by arranging the Clear side toward the top of the stack.
