I have a 50 lb bag of clear commercial cone 5-6 Laguna glaze. What can I add
to this glaze to make it a white? I can only assume this is possible. Any
help will be appreciated. Carol

Test out some 100 gram batches / traditionaly 5-7 Tin oxide would do it,
depending on the desired opacity you want. Also a bit less costly is to
use 7---15 % Zircopax / some folks like to use a mixof both oxides .
also a little Kaolin 5-10 percent will help but it will also stiffen the
glaze, 15 % might get you a soft satin white /especisly if you add some Tin
Or Zircopax. with it.Remember that both Tin and Zirc. are refractory and
will affect the melt in significant %.
good Luck
