30. Greek Roman-candle stars may be made from the formulas given for
rocket stars; but there is also another formula, which produces a rather
deeper tint, but is hardly rapid enough in combustion for rocket stars.
It is the following:—
GREEN ROMAN-CANDLE STARS.
Composition No. 2.
Nitrate of baryta 40 parts.
Chlorate of potash 20 „
Calomel 12 „
Sulphur 12 „
Shellac (fine) 4 „
Charcoal (fine) 1 part.
This composition must be moistened with the solution of shellac. It will
produce a most lovely colour, if the _baryta be pure_.
