Midnight Blue is a rich cobalt blue with red streaks in post firing reduction. Stay tuned for this month's pot which features previous glazes of the month: Blue Moon, Lime Green and Sassy Fat White/Silver Slither, in addition to this month's Midnight Blue.
A note about Hectorite: It's a suspender in powder form similar to Bentonite except it doesn't have to be dry mixed with the other chemicals. It's not a common raku pottery glaze chemical and you may have to search for it on the web. I purchased mine at Highwater Clays, but they don't carry it anymore due to lack of demand (nobody knew what it was used for).
