Cal40x140. Cal40x140 is a semi-course ground calcium carbonate with particle size ranging between 20 mesh (850 microns) and 140 mesh (106 microns). Cal 40x140 is used to stiffen molten glass in the glass manufacturing process, in dog and food as a calcium supplement, and in livestock and feed as a calcium supplement.
Calcium carbonate has a very high loss on ignition (LOI) and for this glaze, the gases of its decomposition are coming out at the wrong time. While there likely exists a firing schedule that takes this into account and could mature it to a perfect surface, ... crawling). Notice talc: It is not finished gassing until 1650F, ...
The two values for calcium oxide as gypsum and as apatite are then subtracted from the calcium oxide value obtained by analysis to give the value for calcium oxide present as calcium carbonate: 51.29 - 0.04 - 0.05 = 51.20% CaO. Calcium carbonate is then computed from this value: CaO (MW) / CaCO 3 (MW) = 0.5603.
