Hi woodwalker. You need to find a fellow high school chemistry student who knows how to do a heat of reaction/fusion balance. 1/8 t of each ingredient will not sever a 1/2" thick angle iron. Plus, thermite is better for demolition than cutting. In our high school chemistry class, the instructor set a few teaspoons on fire. It was not enough to melt through lab tweezers, but it did melt the tool into the blob, rendering it useless. Demolition, not cutting.
As for igniting it, you need finer ground mixtures and more of it. Also, if you are in GA, you can probably get ignitacord. This stuff burns HOT! That's because one if the ingredients is thermite. And it lights easily. You can even light it with hammer and anvil.
As for your angle iron and hot cutting it, don't mess with the forge. Ground fire. Search the blacksmithin' forum for the phrase. It will get you out of jams with the big stuff.
