They worked well for our purpose, and we cleaned them when they clogged, by alternating a hot aqueous NaOH solution and a HNO3 solution, to break organic bonds. Creating unique mixes from THCA is precise chemistry that will spawn thousands of future products. The Hydrogen Peroxide treated extract boiled dry of HP is as smooth as silk smoking in a pipe (over fiberglass) but sucks the big weinie in a vaporizor.

I did mine with left over jar wash and trim runs that people had laying around, My first attempt yeilded bigger diamonds then the hot jar tek. Thanks Skunk Pharm! Ostensibly Methanol would do an even better job winterizing, but would require tighter purging standards. We use an HPLC Reagent grade for this purpose, which we get from the local scientific supply store. Cook at 275 F for one long nap, or until any visible signs of smoke or vapor cease. Starting with the solvent and working our way to the crystal, lets explore the best methods to create the finest diamonds. I have done many experiments with hexane, acetone, alcohol, and ethyle acetate as well as water. and what if it is brown? Dark green or dark amber? 70% iso and 30% water is what the label says. Extremely potent this way, likely owing to the possibility of DEEP lung inhalations without coughing. In a nutshell, many water soluble non cannabinoid ingredients come along for the ride when a polar solvent is used and water is present.
