CRIMSON POWDER
1
For rocket Parachute Ejection Charge
Crimson Powder
has certain advantages over
Black Powder,
including:
- lower combustion temperature which minimizes heat damage to the rocket
- higher impetus (i.e. more potent)
- residue is odourless and cleans up readily with warm water
Ingredients to make
Crimson Powder:
6.2 grams
Potassium Nitrate
4.5 grams
Ascorbic acid.
(In the form of Vitamin C tablets, =11 tablets, 500 mg each*)
0.5 gram
Red iron oxide
30 ml
Water, boiling
* Vitamin C tablets are typically 83% ascorbic acid, 17% cellulose filler.
Place all constituents into a pot containing the boiling water. Stir until tablets are dissolved.
Strain through a double layer of paper towel (or similar filter material) to remove cellulose filler
(this step is not necessary if pure ascorbic acid is used).
Boil mixture until most of water has evaporated and a
wet
“paste” remains, being careful not dry
the mixture.
Scrape paste onto a shallow aluminum pan lined with aluminum foil.
Place in a pre-heated shop oven set to 150 F. (65 C.).
Allow to dry (approximately one hour).
Using mortar & pestle, grind up dried mixture to a granular powder.
Makes approximately 10 grams.
WARNING: DRY FORM IGNITES VERY EASILY & BURNS VERY FAST.
WEAR PROTECTIVE GEAR (FACE SHIELD, LEATHER GLOVES, ETC.) AT ALL
TIMES WHILE PREPARING & HANDLING.
NEVER MAKE MORE THAN 10 GRAMS AT A TIME.
