so i want to pull some cactus with the ingredients listed above. as far as i know everything should work out dandy, ..i was thinking cook with some 1:4 vineagar/water until foamy snot dies down, freeze, thaw, cook in PC, strain, base with lye, pull with limo, salt with fumaric, dry?
i wanted to see if anyone has experience pulling with these materials so i can avoid excessive experimentation, so if anyone can help point out the specifics of how much ingredients etc. or anything i missed?

no need to freeze thaw if your going to pressure cook it, you're lysing the cells anyway,
salt with fasipa for limonene over fasa which seemed to work better with xylene


id salt with vinegar or hcl if i weren't just decanting the tea to drink

could you possibly link to something outlining what you are talking about? im a little confused and i dont see any pings when i search the fasipa method(this is actually going to be my first time working with fumaric acid so i have no previous experience to draw upon in this particular sub-field). btw this is for dry powdered material not fresh. the last time i did something simular i just mixed cactus 1:1 with calcium hydroxide then hydrated and saturated with limo and pulled acetates with white vineagar, got a fairly nice result but was concerned that the method did not get everything out, additionally i thought that adding the limonene to the mixture with all the cactus made me lose alot of the limo aswell.

could one replace the 99% ipa with 99% ethanol?

Yes. 99% ethanol is going to be more expensive though. What are you using it for?
