The glaze effect in the attached picture happened by happy accident where a 2nd glaze applied somewhat thickly to the top of the pot 'cracked' and the 1st glaze shows through. I like this and want more of the cracking next time. Any suggestions about technique or an additive to improve the chance that it will happen again?

This is fired to ^6 in electric kiln, and the glazes are Amaco PC Light Sepia over Deep Firebrick.

you just need a more stable glaze on top of a more fluid glaze. the bottom layer will melt and move with the top parting. pretty simple, just takes some testing.

If the bottom glaze is shiny and the top glaze is matt, you can get this affect.
