Step 2: Molding the grains
A bit of propellant has been heating in the toaster-oven at 200 degrees. After 20 minutes or so, it is nicely soft..
DO NOT HEAT PROPELLANT IN A MICROWAVE OVEN! It will ignite!
The propellant is recrystallized KN/sucrose to which 1 percent red iron oxide (Fe2O3) has been added. This gives it a brick-red color, and increases its burn rate. Kn/dextrose works too, and does too, although it burns with a little less enthusiasm.
A small chunk of propellant is cut off, rolled into a slug, and pressed into the longer molding tube with a short stick. A little more may be added while it is still hot. The tube is filled to within about 1/8 inch of the top, and pressed down firmly.

步骤2:成型的谷物
一点药被加热的toaster-oven 200℃。20分钟后,这是很柔和的. .
不要在微波炉热发射!它将点燃!
这个药是recrystallized KN /蔗糖,1%的红色氧化铁(Fe2O3)已经被增加。这给它一个brick-red颜色,并提高其燃烧速率。Kn /葡萄糖作品中,也有,尽管它燃烧和更少的热情。
一小块的推进剂流动被切断了,变成一个塞、滚压入不会管与短棍。多一点可能会增加时,它仍然是热的。管子被填在大约1 / 8英寸的顶部,压紧。
