at the bottom of this thread plus there is a few references to the use of p toluenesulfonic acid
further up the thread.
its better to learn how it works and get the right chemicals than to trust a premade product
if you ask me.
It sets you free from the man.
I am talking to someone right now and it seems that stirring speed has a lot to do with colour as
well.
red to rose seems to be to slow a stirring speed for the heptane polyphosphoric acid reaction
though this is not a delta 8 reaction but a a delta 9 it may be the same.
overhead stirring may be needed.
though I am waiting on advice from a few people before I am sure of this.
