Yellow star #8

Comments: These compositions are part of a matched set invented by Robert Veline. The compositions mix compatibly to produce a wide range of other colors. Examples are given below. The wood meal in the prime (see miscellaneous compositions) makes the stars a little 'fuzzy', making the stars much more easy to ignite. Without the wood meal prime the stars are often blown blind.
Preparation:

Potassium Perchlorate.............................70
Cryolite..........................................10
PVC...............................................10
Shellac...........................................10
