David F. Posted September 17, 2010 Report Share Posted September 17, 2010 I mixed up a batch of Albany Slip glaze for cone 6 firing and forgot to add the oxide after sieving. I went ahead and used it and it turned out a very nice clearish glaze. What are the cons of using this as my clear from now on? Link to comment Share on other sites More sharing options...
Deb Evans Posted September 18, 2010 Report Share Posted September 18, 2010 Can't say for sure without seeing the receipe. Usually ck for fit and flux > no crazing,good , even melt. red iron is a colorent and because of the amount in albany slip it's acting as flux too.

David F. Posted September 18, 2010 Author Report Share Posted September 18, 2010 Sorry, I intended to leave the recipe. Alberta Slip-80%; Neph. Sy.-10%; G. B.- 10% . Link to comment Share on other sites More sharing options...
Pres Posted September 18, 2010 Report Share Posted September 18, 2010 Sorry, I intended to leave the recipe. Alberta Slip-80%; Neph. Sy.-10%; G. B.- 10% . So you are saying your recipe uses Alberta, not Albany slip? I was wondering about the first post, as I thought that Albany was no longer available except to the very few that have some. I was also wondering why you would use if for a clear when it has such rich possibilities in the brown-yellow range. Your second post cleared that all up-Thanks.

Deb Evans Posted September 22, 2010 Report Share Posted September 22, 2010 So you just mixed up neph sy and g borate ? I looked up alberta slip ( not familar w/ it ) and got this from Continental clay's web site... "Alberta Slip (44# bag) Albany Slip substitute Alberta Slip is a medium plasticity clay-like material. It can be mixed with water to produce a body that can be modeled or thrown on a potter's wheel and fired at low temperatures. Like classic Albany Slip, Alberta Slip melts fairly well from cone 6 up. By cone 10 it produces a glossy brown in oxidation and a tenmoku in reduction. Since it is basically a clay material, it generates a significant amount of gases as it decomposes during melting. These tend to make it an 'active' melter in that it bubbles and heaves as it melts (if applied in a very thick layer). For a better melt add a boron frit (i.e. Ferro 3134) and fire slow enough to give it time to smooth out." so the addition of neph sy and g borate serve the same fuction as ff 3134.
