I fired Bronz Clay Fast Fire for a customer today. The instructions (as I understood) said 1 hour ramping at 829 then hold at 829 for an hour.
I did this, fired it in charcoal as per instructions but had to open the kiln and start letting it cool enough to take out after about an hour.
The problem is it hadn't sintered properly and unfortunately I only realised when I took her best piece and started brass brushing it to see if I could get a shine on it. It broke
I am hoping I can repair it and it was a trial for her so only a simple heart with a thumb print, however, even if I can fix it, will it fire properly next time?
Does anyone have any experience of fast fire bronzclay?
My Paragon SC2 has always fired BronzClay (for 10 hours) with no problem but I did have CopprClay fire badly and not sinter properly before.
I am going to trawl the web and will probably hold it for 3 hours then let it cool completely before getting it out but I thought I'd ask here anyway as you guys know so much about this stuff
