Behavior

(1) in glass-bulb. Occasionally decrepitates and gives off some
water.

(2) in open tube. --

(3) on charcoal. --

(4) in forceps. IV. Previously dipped in SO^{3} colors the flame
green, afterwards red.

(5) in borax. Dissolves easily and when in some quantity gives
an opaline bead.

(6) in mic. salt. Gives the lime-reaction.

(7) with carb. soda. Is infusible. The alkali is absorbed, leaving
the lime on the on the surface of the charcoal.

(8) Special reactions. With microcosmic salt and oxide of copper, gives
the chlorine-reaction. With microcosmic salt in
the open tube evolves fluorine.

Mineral. Pharmacolite

Formula. [.Ca]^{2}[.....As] + 6[.H].

Behavior

(1) in glass-bulb. Gives off water, and emits an arsenical odor.

(2) in open tube. --

(3) on charcoal. Fuses to an opaque bead and emits a strong smell
of arsenic.

(4) in forceps. Fuses to a translucent violet colored bead, the
color being due to cobalt. Colors the flame blue
at first, then faintly red.

(5) in borax. Dissolves readily to a bead strongly colored by
cobalt, which obscures the lime-reaction.

(6) in mic. salt. As in borax.

(7) with carb. soda. Fuses, and emits As. The alkali is then absorbed
by the charcoal, as in the preceding.

(8) Special reactions. --

Mineral. Calespar

Formula. [.Ca][..C].

Behavior

(1) in glass-bulb. Turns white and sometimes decrepitates. Strongly
heated loses CO^{2} and becomes caustic.

(2) in open tube. --

(3) on charcoal. Turns white, or brown if containing much iron or
manganese and glows brilliantly.

(4) in forceps. Glows brilliantly, coloring the flame red.
Becomes caustic and shows a strong alkaline
