Flint chemical formula
Cornmeal. Cornmeal is a meal (coarse flour) ground from dried corn (maize). It is a common staple food, and is ground to coarse, medium, and fine consistencies, but not as fine as wheat flour can be.

[1] Lead glass contains typically 18–40% (by mass) lead (II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO. [2] Feldspars are hard minerals, all of them with a hardness of 6 on the Mohs scale. This lies between the hardness of a steel knife (5.5) and the hardness of quartz (7). In fact, feldspar is the standard for hardness 6 in the Mohs scale. Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff.Figure 22.1 shows some pieces of flint, together with DRHJ’s crude attempt to knap a cutting edge. Knapping a complete knife or arrowhead is best left to the experts! One can only marvel at how these special features of flint were discovered, entirely empirically, by ancient humanoids and extrapolated to the skilled manufacture of sophisticated tools.

Glass dictionary home. A misnomer for English and American lead glass. The term came into use in 1674, when George Ravenscroft’s new glass formula included ground, calcined flint as a source of silica. In the 18th and 19th centuries, the term was applied to decolorized glass, even when it contained no flint. The chemical formula for Torbernite is "Cu (UO 2 ) (PO 4) 2 · 8-12H 2 O". The 8-12H 2 O indicates that there can be 8 to 12 water molecules for every Cu (UO 2 ) (PO 4) 2 molecule. Mineral Series.
