I just tried making paperclay slip from a recipe that I was given at a workshop. The slip has turned out extremely runny and will not dry.
To a 50# bag of dry porcelain clay
Add to one qt of warm water • 7 grams Barium Carbonate • 13 grams soda ash
To a 5 gallon bucket add • 2 gallons of water
Add the barium carb mixture to the water and mix for 5 minutes, and while water is mixing:
get mixture ready • ¾-1 oz of sodium silicate • 1 oz Darvon • 2 oz of water
The paper pulp is made separately and added to the slip. First, it wasn't clear that you don't add the pulp to the entire 5 gallons of slip, so I added it to 2 gallons.
I tried dipping wire and after 30 minutes, it's still wet. I left both the slip and the paperclay slip uncovered overnight in hopes of evaporating water, but that hasn't helped. I would really want to save this batch because I can't afford another 50# bag of porcelain.
I wonder if there was too much deflocullent in the slip? Can I save it by adding a flocullent like epsom salts? Btw, are the epsom salts bought at a drugstore the same used in ceramics?
