Mauve Periwinkle Glaze

50 Custer
10 Gerstley
8   Whiting
17 Silica
6   Dolomite
1   Zinc
4   Barium
4   EPK
Add:
7   Tin
1/2 of 1/8th Copper Carb
1/8th of 1/8th Potassium Bichromate

Generally, i glaze one piece at a time, thus i mix up the base oxides, etc., following which, i use approx 2 tbsp of the mixture and add whatever coloring agents i'm going to use to that.  Add approx. 20ml of water.
(Had read early on in my potter's studies, that glazes which set in buckets for long periods of time are often unusable in later months.  However, dry ingredients, combined and waiting for the addition of the water, will stay workable for an indefinate period of time -- which is why i creat my glazes this-a-way.)
The above is a cone 8 to 10 glaze.  But i fire at 2200 degrees with a 15 minute hold -- so i use a cone 5-6 clear glaze applied over this to bring the maturing temp down.
