hershey8 Posted September 23, 2014 Report Share Posted September 23, 2014 Let's say you're mixing up a 20x5 clear base cone six glaze(Tony Hansen) that allows certain colorants (cobalt carb, copper carb etc)to be added in small amounts. Can you simply substitute mason stains for colorants, or do you have to reformulate the recipes. I'm pretty sure if I substitute,say, 2% Mazerine (mason stain) for 2% cobalt carb., I wouldn't get the same color. But will it alter the glaze in any other way? The recipe I'm using is: Wollastonite(20), Frit 3134(20), Custer Feldspar (20), Epk (20), Silica (20). thanks, ja Link to comment Share on other sites More sharing options...
Mark C. Posted September 23, 2014 Report Share Posted September 23, 2014 Two different things so the answer is yes. Mark Link to comment Share on other sites More sharing options...
Babs Posted September 23, 2014 Report Share Posted September 23, 2014 YOu wouldn't get the same colour but you would not need to reformulate the base recipe in my experience. Some stains may be more fluxy, new word, but by adding it by a small percentage and I am suggesting that 2% is small and doing a run with small increments you should get what you want. If your base glaze is not a running one you should be fine, place on a biscuit if worried. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted September 23, 2014 Report Share Posted September 23, 2014 you need to refer to the reference codes for each stain. Some require so much zinc. Some won' t work with zinc. Some need calcium etc. So it Isn't a matter of re formulating the glaze, but rather finding the right glaze for the stain.Marcia Link to comment Share on other sites More sharing options...
hershey8 Posted September 23, 2014 Author Report Share Posted September 23, 2014 Thanks you all for your input. So much to learn about glazes and chemistry. Just now trying to wrap my head around unity formula. Link to comment Share on other sites More sharing options...
Babs Posted September 23, 2014 Report Share Posted September 23, 2014 Marcia is it the reaction to these elements re. coloured attained that is the important factor? Or is it the effect on the glaze surface that is the determining factor in glaze selection for these stains? Link to comment Share on other sites More sharing options...
Marcia Selsor Posted September 25, 2014 Report Share Posted September 25, 2014 it is the chemistry. The stains are compound combinations and some will react to other chemical differently. so you need to pay close attention to the reference codes for each stain.

Biglou13 Posted September 25, 2014 Report Share Posted September 25, 2014 How safe are red mason stains. 6006 to be exact. Providing they are well glassed in? Link to comment Share on other sites More sharing options...
neilestrick Posted September 26, 2014 Report Share Posted September 26, 2014 There are, or course, exceptions to this rule, but generally speaking a colorant will not effect the melt of the glaze. Different colorants require different percentages, as some react much more strongly than others. 0.5% cobalt carb will give you a strong blue, but the same percentage of iron oxide won't do much at all. There are also limits to how much of any one colorant or oxide can be safely used in a glaze. And certain colorants require specific ingredients in a glaze in order to achieve the desired color.

Min Posted September 26, 2014 Report Share Posted September 26, 2014 How safe are red mason stains. 6006 to be exact. Providing they are well glassed in? Mason 6006 is a chrome tin red, I wouldn't have any worries about using this stain. (usual caveats about handling glaze materials) Mason MSDS for all their stains is here: http://www.masoncolor.com/msds.htm Link to comment Share on other sites More sharing options...
