ACS compatibility

Yes, firing the 650 product at the higher temperatures should work out just fine. I would use the 1470F for 30 minutes schedule.
Keep us posted on how it goes.

Hi, I have a question about using 2 different types of ACS.  I just bought 2 syringes of Art Clay Silver.  I didn't notice, when I bought them, that they were a different type of clay from the 20 gram packet that I had bought previously.  The packet is "650" and the syringes are not.  I notice that they have different firing times and temperatures.  My question is, can I use the syringe clay on a piece made with the "650" without damaging it, if I fire at the temperature and time recommended for the syringe clay?  
Thank you.
