Balcony Shoot #7 - Zinc Star

Date: 2003-09-20


My first try of the so called granite, or zinc dust star.


80 Zinc Dust

28 Potassium Nitrate

14 Charcoal (airfloat)

5 Sulfur

2 Dextrin

Moistened with water and pumped with my infamous syringe star pump. Resulting star 8.5 mm OD, 12 mm long. Cracked slightly on drying as cortex shrunk at a different rate to the core.


Very nice blue-green colour.

Charcoal sparks were drown out by the metal fire, but would show up when the star is actually moving through the air. A small quantity of very hot ash was left behind, probably zinc particles that couldn't escape.

Could use some meal priming.

I also test fired two of these stars from my stargun. They worked quite well, but I still believe a little priming couldn't hurt. I have videos of the stargun shots, but they aren't very good so I'll spare you the download.
