There is disagreement about when it decomposes data sheets vary from 1075 1100c one even indicates 1340c as follows.
Strontium in ceramic glazes.
Strontium carbonate is a source of strontium oxide in glazes which is use.
Fluxes lower the melting point of the glass formers in glazes clay bodies and other ceramic materials.
If you gavw anotger sourxe of strontium carb mix up same glaze using that.
It breaks to darker gold and white with 6 mason stain 6485 titanium yellow.
Strontium carbonate can be used very much like calcium carbonate whiting but also increases a glaze s resistance to crazing and.
Borate maybe needs even more the glaze must be thickly applied.
Fire and see if results the same.
Place both on pieces of biscuit xlay.
Fluxes lower the melting point of the glass formers in glazes clay bodies and other ceramic materials.
Quantity discounts are available.
2 and copper carbonate 5.
However each of these fluxes have different effects on glaze melting crystal formation glaze fit and the response of colorant oxides.
Srco 3 sro co 2.
Well mix a small amoubt of glaze using the strontium carb above mentioned.
I have found several yellow 6 glazes you might be interested in.
