5 tips to prevent pottery warping

Warping in pottery is a tricky problem to tackle and can occur for a number of reasons, here are my tips to avoid clay warping for small flat items such as broaches, earrings, pendants etc:

  1. Use a good quality clay and be sure to wedge it well
  2. Make sure your items are thick enough, my work is at least 3mm thick
  3. Dry items on a flat hardboard, I use MDF boards
  4. Slow dry your items, you can cover with plastic to trap moisture and extend the drying time
  5. Be patient and keep practising, pottery is a craft to learn over a long period

If you don’t currently have flat hardboard’s it is easy to have them made. I recently popped down to B&Q and found a large sheet of MDF which made 6 boards for around £14. They have a cutting service in-store at no extra cost, give them the size of boards you want and you’ll walk out the store with them ready to use!

I’ve seen others place a board on top of their work when drying. This isn’t something I do, my personal experience is this can lead to items cracking.
