Ginny C Posted January 19, 2013 Report Share Posted January 19, 2013 If I succeed in uploading a photo, you'll see a crack where the handle attaches to a bone dry mug. The crack doesn't go all the way around, just across the top half. (I know it's because the cup was a bit too dry when I attached the handle, but I'd like to save it if possible! I dried it upside down so the weight wouldn't pull the handle off, but this crack appeared anyway.) Should I brush in some paper clay slip? I have some that's pretty thick and stiff, so it wouldn't add much moisture. If I don't, is the crack likely to get worse in the bisque firing?? Laguna B-mix cone 5. Will bisque to 06 and then glaze fire to cone 6. Ginny C Link to comment Share on other sites More sharing options...
Mark C. Posted January 19, 2013 Report Share Posted January 19, 2013 Best fixed before bisquing-Tool in some slip and then after drying rub it out with a sharp tool. Then fire.If its still cracked after firing try some bisque fix by amaco. Mark Link to comment Share on other sites More sharing options...
Chris Campbell Posted January 19, 2013 Report Share Posted January 19, 2013 Just be very aware of that mug if you try to use it for hot beverages as that might always be a weak spot. Cracks never really go away. : - ) Link to comment Share on other sites More sharing options...
Mark C. Posted January 20, 2013 Report Share Posted January 20, 2013 You can use a kiln cement on the crack after bisquing to get the strength back.Hi fire mender is one I like as you mix your clay body with it and then mix it so repairs are a good match.

OffCenter Posted January 20, 2013 Report Share Posted January 20, 2013 Toss it or you'll spend more time "fixing" it (and not being sure it's really fixed) than it would take to make a replacement. Jim Link to comment Share on other sites More sharing options...
JessicaGrayCeramics Posted January 20, 2013 Report Share Posted January 20, 2013 Toss it or you'll spend more time "fixing" it (and not being sure it's really fixed) than it would take to make a replacement. I'm with Jim. At least at this point, you can still reuse the clay. Link to comment Share on other sites More sharing options...
emptynester Posted January 20, 2013 Report Share Posted January 20, 2013 I can see why you would like to save it. It has nice details. That being said, I would reclaim the clay now. I haven't had great results with repairs. The glaze seems to high light the repaired area. Link to comment Share on other sites More sharing options...
Iforgot Posted January 20, 2013 Report Share Posted January 20, 2013 I'd shove some sodium sillicate into the crack with a hard brush before bisque. Darrel Link to comment Share on other sites More sharing options...
