5# Blue Pearl Glaze
Description: Blue Pearl Glaze is glossy and has a steel blue background with little white crystal formations. It's nice on it's own or sprayed lightly into other glazes. In reduction: It shifts a lot so spray or dip thin. Be sure to test to get the right application. Put onto a cookie until you dial in the application. In an electric kiln it doesn't shift as much.
Mixing: Add water and screen twice thru an 80 mesh screen. Have it at 40 on a hydrometer to be sure it's not too thick when you dip or spray.
Application: Dip or spray.
Firing: This glaze is nice in a gas reduction kiln and in an electric kiln fired to cone 10.
Note: Be sure to run tests on any unfamiliar slip or glaze before applying to important work.
Clay Body is Important with any glaze: The samples of this glaze are shown on porcelain. Porcelain has a white color which showcases the true color of a glaze. It also has a higher silica content than most clay bodies so it has the potential to melt with your glaze. (see bisque temp info below). If you apply it to b-mix (which has a gray background) it will make this glaze go a little bit more gray in color. It's actually very nice. If you apply this glossy glaze onto stoneware it will probably craze.
Bisque Temperature is Important with any glaze: How high you bisque fire your clay body has a lot to do with how your glaze will attach to the clay body. With porcelain we bisque fire to cone 010. This leaves the body more porous and able to ABSORB the glaze. BMix has more organic material in it and should be bisque fired to cone 08 or it pinholes from it's dirty materials gassing out still behind the glaze. In any case, we've seen great results from porcelain when it's bisque to cone 010. And, not so great when porcelain is bisque fired to cone 08. Bmix has never given us the great results that porcelain gives us.
