Butane? Talk about STUPID !!!
Use the universal solvent - H2O ...
Stuff the pot in a large flask, add distilled H2O, heat, run thru an H2O-cooled condensing tube, and collect in a beaker. Oil floats on top of the H2O - pipette the oil out of the beaker. Have to ensure to add H2O to the flask as it evaporates.
Exactly like making moonshine ...
It may take longer than using butane, but MUCH safer, also only costs about $30 for the lab equipment ...
Water’s not a universal solvent. It doesn’t dissolve non-polar compounds.
This dumb ass blow the side of an apartment out 6-9 months ago. The taxpayers and owners are the ones paying for the damage.
THC is water insoluble. The method you’re designing is used to make commercial Hash — a more desirable compact and convenient form for either cooking or just traveling with. It’s done using crushed ice, water and sieves in the form of a set of bags in decreasing sieve size.
So basically with Butane or Alcohol or some other solvent you gather what passes through the filter, THC dissolved in the solvent, and with water and ice you gather what’s left in the filter, THC suspended in the water.
They both need to be dried. In the case of solvent, the hacks use electric heating elements while the pro’s only use a vacuum chamber, or the in between who would merely let it sit and evaporate itself — in a safe spot presumably.
For the water based extraction, it’s pressed and compressed over and over and then cured for several weeks in a cool dry place or for a few days in special curing ovens.
The oil ends up in a very sticky liquid form — is difficult to work with unless you’ve got it from a true pro like Rick Simpson’s Phoenix Tears oil.
The water method yields a lump of heavy THC/Particulate lump of clay — called bubble hash by some.
This as opposed to the dry and shake method or the more ancient hand rubbing method.
