of chloride of sodium; then, in a smaller quantity, chlorides of magnesium and of potassium, bromide of magnesium, sulphate of magnesia, sulphate and carbonate
When we remember that lime, either as a phosphate or carbonate, enters into the composition of the hard parts, such as bones and shells, of all living animals, it is an interesting physiological fact  to find substances harder than the enamel of teeth, and coloured surfaces as well polished as those of a fresh shell, reformed through inorganic means from dead organic matter -- mocking, also, in shape, some of the lower vegetable productions.
It is much softer, more transparent, and contains more animal matter, than the natural incrustation at Ascension; but we here again see the strong tendency which carbonate of lime and animal matter evince to form a solid substance allied to shell.
White quartzose sand," Paul rattled off, "sodic carbonate
, slaked lime, cutlet, manganese peroxide--there you have it, the finest French plate glass, made by the great St.

Coral, clams, and many other organisms build their shells by bringing carbonate
ions together with calcium to form three different calcium carbonates

Efforts will focus on more economical clays, finer ground calcium carbonates
(GCCs) and precipitated calcium carbonates
(PCCs), more cost efficient glossing aids, and cost effective coating binders.
We assume diamictites represent cold temperatures, and we assume the carbonates
represent temperatures like in the Bahamas or the Yucatfin," says Kaufman.
