Leslee Posted December 23, 2013 Report Share Posted December 23, 2013 This is a really silly question. I have been working with clay for years but just started making ornaments this year and I am having trouble with my clay curling up while its drying. I normally make small bowls, jewelry, beads and thrown pots years ago never had this problem before. I know I'm not the only one because my friend has the same trouble. Any guidance would be greatly appreciated? Link to comment Share on other sites More sharing options...
Guest JBaymore Posted December 23, 2013 Report Share Posted December 23, 2013 I thought this topic was related to the coming winter Olympics. best, ..............john Link to comment Share on other sites More sharing options...
Marcia Selsor Posted December 23, 2013 Report Share Posted December 23, 2013 It sounds like a fast drying problem or a draft. What type of shapes and clay are doing this? Marcia Link to comment Share on other sites More sharing options...
Leslee Posted December 24, 2013 Author Report Share Posted December 24, 2013 Thank you Marcia, It is White low fire clay. Its pretty humid here in HI so it can take 3-4 days to dry. I was thinking of getting some boards and stacking them to keep it flat while drying. Thinking about it my terracotta pieces don't seem to do it.

Chris Campbell Posted December 24, 2013 Report Share Posted December 24, 2013 I made thousands of ornaments at one time and had this problem with porcelain clay. I got the loss rate down by cutting the shape at right angles to the direction the clay went through the slab roller. If I forgot and cut them with the direction the clay fed through the rollers, the loss rate jumped again. I could find no other common denominator ... The way I dried them did not affect the results as much as the cutting direction. Terra cotta is a much more forgiving clay body ... you can do almost anything to it and all is good.

Mark C. Posted December 24, 2013 Report Share Posted December 24, 2013 If these are flat forms(cookie cutter stuff) dry them between a piece of sheet rock with board and weight on top. I think its to late to stop this as a sport in the winter Olympics this year but you can keep clay flat with the right handling. Mark Link to comment Share on other sites More sharing options...
Pugaboo Posted December 24, 2013 Report Share Posted December 24, 2013 I made a lot of ornaments as well and this is how I do it. I use Little Loafers ^6 clay. When I roll it through the slab roller I flip AND rotate the clay 45degrees with each 1/4 inch adjustment in thickness. I then let it set up on the slab roller a bit before cutting out the shapes. I did a lot of snowflakes with a bunch of interior cutout designs (see the attached picture). Once I cut out the shapes I put them on drywall and then dropped the drywall with the ornaments on the floor from waist height. I then sandwich them between 2 pieces of drywall and allow them to dry slowly for a day or 2. Once they are dry enough not to flex at all, not bone dry but on the far end of leather hard I move them carefully to mesh shelves and allow them to dry the rest of the way there. I have no issues with cupping as they dry. T Link to comment Share on other sites More sharing options...
Leslee Posted December 24, 2013 Author Report Share Posted December 24, 2013 Thank you all so much. These all make sense and I will do. I've never worked with paper clay but I might try it. Two questions 1)you don't cover the drywall and the clay doesn't stick 2) do you tape the edges of the drywall to keep it shedding? Link to comment Share on other sites More sharing options...
Marcia Selsor Posted December 24, 2013 Report Share Posted December 24, 2013 tape the edges of the dry wall. 2" duck tape is fast fix. I have 2 x 2 shelves on an old bakers rack. I put my slabs on 2' x2' or more drywall and slide them onto the shelves. The whole rack is wrapped with a heavy plastic. I live in humid South Gulf Coast Texas. But A/C is bad for clay because of uneven drafts. Marcia Link to comment Share on other sites More sharing options...
