QUESTION: Hi Leisha,
I am currently trying to start my own studio and I have recently acquired a million molds.  I have only done ball clay pottery work in the past.  I am looking to purchase dry slip mix that will end up food safe/high fire.  Some pieces that will be purely decoration will be fine with low fire but I definitely want to be confident and say that the platters are "food safe".  I do not even know where I can get the dry mix.  It would also be helpful to know if there is a porcelain slip mix and if it is safe.
I really appreciate your help!

ANSWER: Dear Chrissy,
Congratulations on taking on such an adventure. I wish you the best. If you can tell me what city you're in, I'll find you a reliable supplier for all your needs.

QUESTION: I am in Washington County, PA.  Pittsburgh is about a half hour away.  It has super close access to WV panhandle and OH.  I looked into Ohio Ceramic Supply (which is about 2hrs).  What would the name be of the high fire slip?  THANKS!

Answer
Dear Chrissy,

Here's one in Pittsburgh;

Standard Ceramic Supply Co.
412-276-6333
PO Box 16240
Pittsburgh, PA 15242-0240
Email: info@standardceramic.com
www.standardceramic.com

They manufacture clay and distribute raw materials, glazes and tools.

Tell them what you're doing and they should be able to hook you up. If they don't have what you're looking for, they should be able to point you to the next nearest supplier.

Slip is called slip. There are just different firing temperatures. "Earthenware" is low fire slip. There is mid-range slip that fires at cones 5-7 and then high range.

Hope this was helpful. Leisha
