My first in home Bronze Firing

My somewhat long story of the first time I fire BronzClay at home in my own lovely little kiln.

For those of you who may not know, BronzClay has a much more complicated schedule than Silver clay or PMC. I took a Bronze class some months ago and I really like it, it suits my rustic and primitive style. But for some reason I haven't figured out I've been chicken to fire it at home. In the last year of jewelry making I do things I don't know how to do all the time, no problem, but this one stopped me in my tracks.

When I first learned to use Bronze, I couldn't fire it in the kiln I had. It was a manual kiln and would have been very difficult to babysit it all day using the Bronze firing schedule. I think there are many variations on this schedule but the one my instructor uses, the amazingly awesome and fun Patrik Kusek is 500 F per hour to 1550 F, hold for 2 hours. See why I didn't want to try this with a manual kiln OY!!!

So I purchased a programmable kiln quite some time ago, but I've never gotten the courage to use it. I took another Bronze and Copper class with Patrik and decided I had to face my fear and program my kiln and fire Bronze and now Copper at home.

The day after class I programmed it, and there it sat for about 3 weeks. Until today!!!!!! I made 3 fairly simple pairs of earrings, in case I ruin them all :). Loaded the container, put it in the kiln and turned it on. It shot up to 1,000 F right away, whaaaaat!!! So I turned if off and re-programmed it, and checked it several times, turned it back on and crossed my fingers.

Tic toc....so far so good, it's at 1,000 now for an hour.

Tic toc....10 minutes to go, then hopefully my kiln will go to 1550 for 2 hours and I'll have gotten through it.

Woohoo, in the home stretch. I won't be able to get in and see if this jewelry survived the firing until tomorrow.

So tune in tomorrow.

  2. Believe me Cindy, it's not easy. I am the kind of person who is standing by my kiln when it goes off and I done my big heavy gloves and use big long tongs to pull everything out right then and there. It's going to be very hard to wait until morning. :)

  3. What firing timing are you using??
    I hold the temperature at 1550 for three hours.
    It goes 250 per hour ultil it reaches 1550. Almost 9 hours !!!!

  6. 2 hours isn't going to be long enough for bronze, like Lorena I have to fire mine for about 9-10 hours. Not sure what you have to wait overnight too before you take it out of the kiln. Good luck anyway! :)
