Glen Peters Posted February 25, 2013 Report Share Posted February 25, 2013 Hello Being out of the game for 25 years I cannot recall how to make slip! I have a small blender --Can I get away with just adding wet clay and water??? And how critical is it to use slip made from the same clay when attaching by score&slip? I intend to do mostly raku firings... The clay I'm using matures at cone 6 but It's unlikely I'll ever get that hot? Any other slip tips appreciated Thanks Glen Link to comment Share on other sites More sharing options...
Chris Campbell Posted February 25, 2013 Report Share Posted February 25, 2013 For ordinary, hand building slip purposes clay and water in a blender will do fine. If you do slip casting you need a specific recipe. If you want to decorate with it you might need additions to help with shrinkage and cracking. As to attaching with the same clay slip ... yes, that works very well and is easy to do with bits of dried clay ... but you can also just use vinegar & water to get a tiny bit of slurry on the surface.

neilestrick Posted February 25, 2013 Report Share Posted February 25, 2013 Put bone dry clay in a small bucket of water and let it sit overnight. In the morning pour off most of the excess water before blending. Link to comment Share on other sites More sharing options...
Glen Peters Posted February 26, 2013 Author Report Share Posted February 26, 2013 Thanks for your answers And, if I may, I have another question --I have quite a bit of clay that was frozen, some of it has sat untouched in a warmish (60degre) environment for several years, some of it I thawed last month only. What would help to recondition it or can I just go ahead and use it? Link to comment Share on other sites More sharing options...

I don't know what kind of reconditioning you have in mind, but unless it has dried out, all it probably needs is to be well-wedged. Freezing doesn't harm clay in the bag anymore that it does in the ground. Jim Link to comment Share on other sites More sharing options...

Any other slip tips appreciated Thanks Glen Glen, The blender is perfect for making instant slip from dry scrap of whatever clay body you are using at the moment. The main feature is you can control the viscosity easily by add small amounts of water to go from brush painted to sprayed slip for whatever job is needed. If the clay is designed for Raku it is probably loaded with sand/grog so it will eat up the blades in your blender like liquid sandpaper. However, blenders can be found down here at yard sales for a few bucks. You should have no problem with assembly using slip made from the clay body. Good luck with getting back into clay.

yedrow Posted February 27, 2013 Report Share Posted February 27, 2013 I like to break dry clay up into chunks about 3/8th (centimeter) size chunks or smaller, then I just mix it into some water and use one of those hand mixers. John Britt has a great video about mixing slips on youtube... Link to comment Share on other sites More sharing options...
