Standard materials
The 170 materials in Glazecalc's standard library, from feldspars and clays to frits and boron sources, each with its oxide analysis and its hazards.
Every recipe in Glazecalc can use these materials. Each page gives the oxide analysis and unity contribution Glazecalc works from, the hazards as the library records them, and where the figures come from.
