  1. Posted just now Hi, wondering if anyone can help I have a large bowl with a small 2cm crack from the rim, it has been bisque fired and what can i do to repair? I have a similar problem, but longer on another bowl. thickness of sides and rim all ok, it is hand built so i do try to compress as much as i can around the rim. Also where Iā€™m having the firing down my work (and I guess others works) are coming out with black marks like dots on them, just wondering what that could be. Many thanks/ā€˜
  2. Hey all, using white cone 6 stoneware- B-mix 5 WC-401 I have been making some little 8-inch coral wall hangings- I throw bowled plates and fill it in with coral looking bits. They dry slowly and they usually make it through the glaze firing fine but then I like to add some glass (I bought some stained glass and mosaic glass pebbles- photos attached (the ones I bought are different colors but same type)) and put them in for another glaze firing and then they often crack at this step. I try not to use too much glass since I know that can cause cracking and often they just crack a little bit in the back but sometimes it goes all the way through (photos attached since Im not good at describing this) I have 2 questions: 1- after they're bisqued, can I put the glaze on them, let it dry and then put the glass on top so that I just do one glaze firing or is there any cost/benefit to doing it separately? - I did it separately this time because I decided I didnt like how they looked just with the glaze. 2- I've heard you can put sand underneath pieces to be like a shrink slab but I fire in a community kiln and they dont seem to be open to that; would making little clay coils or rolling out cylindrical strips and putting them under the corals when I do the glass melting help to prevent cracking? -I figured they were cracking because of friction getting caught on the kiln shelf any other thoughts/suggestions on how to do these? I just made a few more and trimmed the back of the bowled plates to add a little foot thinking that might help since there will be less surface area touching the kiln shelf but they are still drying thanks!
