In this live episode of Cracking the Kiln, I’m digging into a question I hear constantly in studios: “What’s really happening with my clay body?” Over the last several years, the CMW team has collected and tested scores of commercially available clay bodies, and this stream is where I start connecting the dots between the numbers, the real-world studio symptoms, and the frustrating inconsistencies people run into. If your clay suddenly starts cracking, warping, bloating, or behaving “different” even though you didn’t change anything, this is exactly the kind of problem clay body profiling is designed to make visible. My goal here is to break down the science in plain studio language—why a clay body performs the way it does, why two bags with the same label might not fire the same, and how to troubleshoot persistent issues without guessing. I also talk about how we use these profiles to help students make better decisions: choosing bodies that match their firing range, forming methods, and glaze fit needs, and then adjusting process when the material isn’t cooperating. If you want to follow along and build your own understanding step-by-step, I point you to our free clay body profiling course so you can use the same framework in your own studio.
