These two platters are an example of what can go wrong, even at the last minute--both failed during the final firing--as reflected in the cracks that developed in the cooling process. Always a disappointment, esp. after spending 5 to 6 hours building and glazing them. No worries, just more experience--and the next ones will be easier and faster to build. By the way, the Key West Lighthouse was a second try...now on to #3!
