Potter's Council

29 October 2013 - 09:53 AM

My wife and I recently received an e-mail invitation to join the Potter's Council for $52 a year.  Not having heard of it before, we're wondering if it's worth it.


3D Printing Clay

07 September 2013 - 09:13 PM

Just curious, I've heard a lot lately about 3D printing plastic and metals.  Has anyone heard anything about 3D printing clay?  Seems like if it can be done for plastics and metals that it could be done for clay as well.


Cracking In Mold

I have a mold in which as the slip dries it cracks.  What causes this and what can be done to prevent it?  I'm using slip straight from the shop, no used stuff added.


Mixing plaster

27 June 2013 - 11:02 AM

Next thing I need to figure out is how much plaster to mix. The volume of my box minus the volume of the bowl I'm making is 864 cu in which is 3.74 gallons which is 31.3 lb of water. For that amount of water I need 44.7 lb of plaster. But that will make too much because adding the plaster to the water will increase the total volume. So how much water and plaster do I need to fill my 3.74 gallon box?

Thanks,
Evan

Making a mold

25 June 2013 - 10:55 AM

I am trying to make my first mold and have made a wood box to surround the mold. I have some Murphy's Oil Soap to use as a release agent on the inner part of the mold. I was wondering if I could line my wood box with a black plastic garbage bag so the USG No 1 Pottery Plaster doesn't leak out of the wood box. I have read that the plaster heats up when it's curing. Will it get too hot and melt the plastic?
