Another fine explosive mixture.

18g of starch
35ml HNO3 67%
65ml H2SO4 98%

-Pour the two acids into a 250ml beaker, and let it cool to about 15 degrees C.
-Add the starch in small portions, temperature may rise, but that doesn't always happen.
-Heat it on a 40 degree C hotplate for about 90 minutes.
-Pour the mixture into 400ml of distilled water and let it cool.
-Pour in 3 litres of distilled water, spread over about 15 beakers, and let the starch sink to the bottom of the beakers.
-Let it dry, and neutralize it with a sodiumbicarbonate-solution.

And that's nitrostarch. It's not that hard to detonate, some of the test batches caught fire at about 50 degrees.

This stuff is easy to make but its nothing but a god damn mess to produce. The starch clogs everything its gets in contact with so filter is almost impossible even with vacuum filtration.

Yeah, it's pretty sticky indeed. Most of my glass is still covered in powder. And it came out in a very bright yellow color, I expected it to be much whiter. Well, as long as it works, I'm satisfied.
