Not All It's Cracked Up To Be

Ever wonder why raku pottery is often much more expensive than traditional stoneware pottery? About a quarter of the pieces are a disappointment when they come out of the firing. Another quarter or third of the pieces end up cracking during the high thermal stresses characteristic of this firing technique.

 

This particular piece looked nice out of the reduction chamber but close inspection revealed several hairline cracks around the rim—off to the reject pile!

 

Raku is a lot of work and has a high failure rate. But when things go right, it can be spectacular.
