Lucie Claire Posted May 14, 2018 Report Share Posted May 14, 2018 I have a bucket of old porcelain casting slip that I made a couple of years ago, and I'm wondering if I can reconstitute it. It's pretty chunky, it was originally deflocculated with Darvan 811. Can I get it back to a proper consistency for casting? Should I add more Darvan? Also, does Darvan expire?

Only way you will know for certain is to test it. BUT Is the cost of your time to do so less than the cost of a new bucketful? Probably not. If you're time rich-cash poor, go for it, otherwise, dispose and start again. Link to comment Share on other sites More sharing options...
Magnolia Mud Research Posted May 17, 2018 Report Share Posted May 17, 2018 I Agree with Chilly, ... and, take the 'to be disposed" slip, let it dry to a thick stiff mud, and have fun carving sculptural objects, making slump molds, stamps, and all sorts of "stuff". Then throw away what's not useful. LT Link to comment Share on other sites More sharing options...
