Using already decarb’d crude, I’ve added live HTE to the crude to create a suspension of 20% HTE and 80% crude. When agitated or mixed gently at temperatures 130F+ the suspension creates a significant amount of bubbles and begins to foam a lot.
When mixed independently of one another the foaming isn’t observed, only after the crude and HTE have been mixed does the bubbling occur.
Any thoughts on why this is happening and how to avoid?
Did you solvent test your hte?
Maybe its the terpenes burning off?
Under what parameters did you decarb your crude?
Your HTE (probably) has enough THCa that it will start to decarb under heat, creating bubbles as well.
I agree with this ^
Also residual hydrocarbons, if present in the HTE, could create a similar effect
Yes, sub 50ppm @Dukejohnson
@MWCanna decarb at 140C for 2hrs.
U can add a lil heat they will rise and it’ll bubble out but I’m not trying to decarb just get the bubbles off once mixed
are you mixing these at room temp or warm? if you’re mixing at room temp, the high viscosity of both materials could simply be trapping air worked in during the mixing process
This gets my vote as well.
@Dr_J do you have cannabinoid content on that HTE.
30% cannabinoids, most of that as THCa would not be out of the question, and could certainly foam as it decarbed.
Why it would decarb faster (at a lower temp) when mixed with your crude I’m not even willing to guess.
Mutter mutter catalyst mutter mutter
Edit: that assumes you heated hte to 130+f alone at this step…
Seconded
What about powders in the crude 
If cy isnt willing to guess 
Edit and the ever sopopular F to C displacement
Solvent. Test your lab
Lol at the guy who’s pointing out that pointing viscous substances entraps bubbles. So basic……
yup. my thinking was that it’s so basic they might not have thought of it; after all they made no mention of heating while mixing (if it did i missed it in my first readover). worth throwing into the conversation.
Terpene alcohols will cause this effect with the right mixture of waxes and cannabinoids. Many mixtures will look almost like a carbonated soda frozen in time with tons of extremely small bubbles forming. You can actually use this bubbling effect to “float” solids out of a mixture.
