DENS - Density (Specific Gravity)
HMOH - Hardness (Moh)
GSPT - Frit Softening Point
Popular bone-ash substitute. Melts only superficially, with core hard and granular, so fuses with a difference, with very strong opacifying attributes. An interesting calcium phosphate to use where either calciums or phosphates are called for in glaze formulas, such as those calling for bone ash owing to the molecular similarity re- Ca3(PO4)2 in contrast to Ca5[(F, OH)(PO
4)3]. At temperatures below 1200ºC, apatite is a good substitute for bone ash, as, owing to its contribution of fluorine, it is a stronger flux.
