Magnesia dissolved in much smaller quantity, and barytes seemed to decompose the sugar entirely.
barytes is mined in the north of England and in County Cork.
The mineral barite is a heavy white sulphate of barium, frequently called "barytes" or "heavy spar."
The specific gravity (4.2) of this compound is lower than that of barytes.
barytes scratches easily with the knife, and from its great specific gravity is often called heavy-spar.
The sugar made in this way, I was told, contains no trace of barytes.
The sulphate of barytes, calcareous spar, and white crystalline masses of quartz, characterize the uplands.
At this locality, the ore is accompanied by the sulphate of barytes, and is sometimes crystallized in cubes or octohedrons.
