Demonstrating Glaze Fit Issues to Students

Glaze and body can both be adjusted to solve crazing and shivering problems. This describes a simple project to create body glaze combinations guaranteed to craze and shiver to demonstrate the principles involved.

At the risk of sounding like a broken record, I want to flog the issue of crazing again. I continually meet students who have no idea about what it is. This is incredible to me. No piece of functional ware should be crazed. Period. This is our duty to customers.

So take this whole issue seriously. Examine your colored glazes very closely to see if they are crazing. Stress your ware using boiling and ice water to bring out delayed crazing. For more information, search for 'crazing' at digitalfire.com.
