just for the sake of making some use of this thread.
Expect 30 grams of dried i2 crystal if using hydrogen peroxide and muratic.
A slight more is available in the stock 7% depending on your ratios and time... making a max of about 35g
oh ya... dont be a dumbass and do this reaction in an open container... do it in a closed milk container and filter the shit outdoors if possible... unless you want small i2 crystals forming in your nose and so on.
