shrinkage
Japanese: 縮み
Shrinkage that occurs when firing a single sheet or with powdered material. This can be adjusted by the number of layers or by using weights.

Shrinkage is the phenomenon in which glass contracts after firing. When fired as a single piece, surface tension causes the edges to contract inward, increasing the thickness. In the sintering of powders or frits, shrinkage also occurs as the gaps between particles are filled.
You can adjust the degree of shrinkage by increasing the number of layers or placing a weight on top.
