I did not dry them fast so that would not cause this. The thinner pieces – like the butterfly, had no cracks, but had fallen apart. I ‘glued’ it’s parts together with water.
So I cooked up a new batch of normal Cold Porcelain and mixed about 1/3 Normal with 2/3 New clay – made a second set of pieces…same problems.
Determined not to be thwarted, I then made a mix that was about 50/50 Normal/New…this made medium sized pieces and it had less cracks. The smaller butterfly was lovely – BUT I glued this one with glue and it still fell apart – Huh?!?
- So my recommendation is, you can add a SMALL amount of Whiting / Calcium Carbonate to your cold porcelain and you will find the results are just a bit more of a buff colour and that’s all.
- If you add it in any significant quantity, you may end up with cracks if you do larger items
- Larger amounts of Whiting are fine for thin pieces or small items.
Hope this is useful – I’ll be trying other variations and will chronicle them here so do sign up for RSS or email updates!
