Soluble: MagnesiumCompounds

These compounds are strong flocculants.

The chlorides in the presence of Barium Carbonate form Barium Chloride. This material is much more hazardous than barium carbonate. These mixtures in my opinion must be avoided unless the people using it have a real understanding of the hazards involved and know how to properly dispose of them.

Both magnesium Sulphate and Calcium chloride have been successfully sprayed into cone 9 vapor firings. The surfaces are what one might expect although the specking of ash does not happen and the fume acts a fume, not like solids that settle from the stream of gases. If you spray much magnesium sulphate in the kiln the surface will shiver. Of course this will also glaze your kiln and shelves.
