1kg dried cacti skins- powdered
add to 5 gal bucket with 3-4 gallons of water
with paint mixer on a power drill mix the cacti/water as slowly you add 1-2 lbs lye.
glasses/goggles. gloves etc are a must- base burns hurt
now let the mix sit for 12-24hrs or until it has turns completely watery (lye digesting the pulp)
i like to keep things warn during this stage. set bucket in large tub- and periodically add boiling water to tub to keep the bucket hot.
add xylene or toluene gently mix. siphon off w/clear tubing
here are notes from the last run:
took partially dried out cacti
blended w/minimal water
boiled until it stopped foaming- it was about 4gal of material
added to 5gal bucket w/2 lbs lye added slowly while rapidly blending w/paint mixer
material became watery in 1hr
added xylene toluene mix- blended again
separated quickly and did 4 pulls in 4hrs
salted w ph down used very hot water bath and funnel/cotton ball to separate and filter all the saltings
reduced volume on gas range set to high
added acetone
yield 10+ grams
