## Formula ##
+Since we need 177 grams, let's make 200 grams of propellant in this batch.
+
* 65% Potassium Nitrate (130g)
* 35% Sorbitol (70g)
* 1% Red Iron Oxide, added post-melt (2g)
About 4 hours later, the card stock was pulled off the test strand, which
proved to still be a bit on the pliable and "tacky" surface side.
+
+## Observations ##
+
+After casting, further reading on Nakka's site indicates initial melt is
+at about 91C, or 196F. Fully melted at 125C, or 257F. Discoloration at
+175C, or 347F.
+
+Nakka says wait 24 hours before trying to pull the core rod. The propellant
+will remain pliable after cooling, thus can be deformed if handled sooner.
