Profile Information

What is your experience with ceramics in general. (Long answer encouraged)
I've been playing with clay for 50 years on and off. I have recently retired and am planning on spending more time than ever before with clay. Learning to control glazes appears to be my greatest challenge.If only I had listened to all those chemistry lectures in high school and college!
What is your current involvement with electric fired ceramics? (long answer encouraged)
I have a small kiln an even smaller kiln and a tiny test kiln. I got the mid size when I was 15 years old, the largest for 50 dollars off EBay a few years ago and the tiny test kiln was free on the side of the road. (Almost New)All of my work is electric fired. I admire reduction fired work but doubt I will ever be able to justify a wood fired kiln. I have a PC that controls my kilns recording and managing the temperature to within 2 degrees. This has given me many more opportunities to control what I do. Understanding the glazes I use is the key now.
