I don't know about all of you, but it still makes my head spin when I accidentally find out that my common studio glazes interact in a really unexpected ways... I've been living with these glazes for 2 years now, and I test for these things after all. But this glaze combo slipped through... until now.
I haven't made this combo jump through any hoops yet, but it seems to be acting like a cone 6 OilSpot glaze. Small Amber bubbles are floating through the WhiteLiner and healing over.
