Crawl/Crackle glaze ideas

Texture/Crawl Glaze c 6 ox or red.
Nepheline Syenite 70%
Magnesium Carbonate 25%
Ball Clay 5%

adding colorants or stains will give this different colour

I didn't want to use a whole heap of Nepheline Syenite as it is expensive...

One technique to make this happen is to add 15-20% magnesium carbonate (testing required to determine amount) to a low fire transparent glaze.

I'll be trying this out in my next glaze firing!!
