A couple things that I don't believe you understand.
1) That poo that you scraped off the side of your bowl isn't nor ever will be hash. Hash is a bunch of trichomes that have been separated from the original plant matter. There are several methods and procedures to make hash, but soaking your piece in 99% alcohol will never produce hash.
2) You mention you want to cook with hash. This is totally possible, look into making hash butter and you can pretty much use it in anything. 99% iso alcohol is 99% alcohol and 1% water. If you let the iso hash oil dry properly all the alcohol will be evaporated out of the oil.
I think you should do some reading in the Hash section of this forum.
