Sean Tessandori Posted November 14, 2019 Report Share Posted November 14, 2019 Hi, For a bit of context I make pottery that I apply layers of slip to create a raised bumpy surface. When my work is in greenware stage the dots are easily knocked off, and although I can load my work with out knocking any off in my current studio situation Im not the one loading the kilns and I've been constantly getting pieces that have multiple dots missing. I was wondering if anyone knew of something that will help to keep attached pieces or slip trailing from being knocked off by people during loading. I was thinking maybe an organic hairspray or to coat the piece in wax Link to comment Share on other sites More sharing options...

Don't wait til leather hard or use a mixed slip. It would be difficult to match wet->dry shrinkage between your clay body and a slip that is mixed.

Min Posted November 14, 2019 Report Share Posted November 14, 2019 I'ld try mixing up the slip with part water and part magic water. The sodium silicate in the magic water helps the clay surface dry hard. Would have to try a few tests to see what ratio of water:magic water works best. Magic water recipe if you don't have it already is 1 gallon of water, 3 tablespoons of sodium silicate and 1 1/2 teaspoons of soda ash. Welcome to the forum.

It's also a deflocculant so the slip can use less water and decrease shrinking Link to comment Share on other sites More sharing options...
