This is a nice base, coppied from ClayArt Glaze Database Search Results,of
the ceramic web. I tested, very special. I will try to rebuild it with my
locals, try to use spodeman insteade of lithium carbonate.
Glaze Name: Jaquie Rice Lithium Base

Percentage Analysis for Jaquie Rice Lithium Base:
62.39 % SiO2
4.11 % Al2O3
13.37 % B2O3
0.26 % K2O
3.19 % Na2O
9.92 % CaO
1.66 % MgO
4.94 % Li2O
0.22 % Fe2O3
Possible Health Hazards: Silica: free silica-wear a NIOSH approved dust mask
when handling dry material
(from Laura Zindell - a former student at RISDE) This is a nice textural
low-fire glaze - fire to 04 for semi-matt, 03 for semi-gloss. For opacity
add 8% zircopax. Colors: green - 2% chrome oxide, 2% copper carbonate;
turquoise - 4% copper carbonate, 3% rutile; blue - 2% cobalt carbonate;
black - 3% cobalt carbonate, 12% RIO; yellow - 4% rutile; yellow brown
(especially nice) - 16% RIO. Note: all of these glazes contain large amounts
of gerstley borate, which is soluble with time. If you don't use the glaze
up within six months or so you may have to toss it and mix a new batch. An
alternative is to replace all of the gerstley borate with 3134 frit.
