I wondered if anyone could help, I am looking at combining art clay silver sterling and effetre/CIM. I have already mastered the pure silver version in my Maxine and have decided for strength and saleability, sterling would be better. I have done hours of research into firing schedules and the only one I have found if for COE 90 so it suggest firing at 790c. I have found another schedule that suggest the second firing at 650c, and I know this is the softening temperature of effetre. So I was wondering if anyone knew would happen to my beads if I firied them at 650c in a firing tin, in carbon, for about 1-2 hours. I will give it a test but just wondered if anyone had any tips?
If this helps,

"At 1100 deg Moretti/Effetre is going to go plastic and will soften and susceptible to distortion... " 1100deg F equates to about 593 deg C

Thanks for that Pat :) I have fired the pure silver clay at 600c (the glass survived perfectly) ... wonder if I can push it to 650c but don't want a congealed mess in my tin of carbon :(
I have fired pure silver onto glass at 650 - you just need to be careful to have it suspended so it isn't touching anything or you risk having marks from whatever touched it - I know this from experience ;)
As far as putting it in carbon, you will end up with carbon shaped indents all over it I fear! Let us know how you get on ;D

Thought this might be helpful to you. Janet
Also remember that the maximum firing for the Maxi is 650 deg C......
