Strontium carbonate is a source of strontium oxide in glazes, which is useful as a flux. Strontium carbonate is a common substitute for barium carbonate, particularly when the desired effect is a color-responsive matte. If you switch strontium carbonate into a barium-containing glaze, use roughly 75% (by weight) and definitely make sure to test first! Because some information suggests that strontium carbonate is a safer material to handle than barium carbonate, some studios and artists certainly rely on this as a permanent substitute material.
