Clay shrinkage. Pesky clay shrinkage. Nearly every beginner with clay has had the experience of getting their first piece out of the kiln and thinking “this was so much bigger when I made it!” Of course, clay shrinkage is a fact of life and as you build your skills you learn to accommodate for it by making your pieces a bit bigger.

In some cases, like when working on an architectural ceramic project, calculating the precise shrinkage rate of your clay is crucial. In today’s video, an excerpt from our latest Ceramic Arts Daily Presents DVD Studio Scale Architectural Ceramics, Stephani Stephenson explains how to calculate shrinkage and make a shrink rule. I thought this would be a good clip to share because, even if you’re not working on an architectural scale, knowing how to calculate shrinkage is a good skill to have. – Jennifer Harnetty, editor.
