Scarva Nano Colours NAK001 Brilliant White Stoneware Crackle Glaze From  £16.14

This was a replacement for a product that Scarva don't seem to stock anymore. However, it's even better! It gives a lovely fine crackle which is about the same size as the enlarged photo.

I used this on a 6 cone firing because the accompanying glaze could not go above this. I was worried but all worked well. I applied 4 coats but felt it sat a bit to thick. Next time I did 2 coats and that is maybe too thin. 3 must be just right
