What kinds of pressure are we talking about here? Is there a size, material or make that would be well suited to my scale (half ounce runs max) ?

If you’ve done the reading, you should know this.

It’s important to learn so you don’t make a bomb, buddy.

Did you catch this thread?

Okay so we are gonna cook down an unknown amount of cannabis oil (THCa to THC) while trying to retain terpene profile. Ideally, the only thing we should lose is CO2 gas from the THCa → THC conversion.

Let’s say we are using 16 oz mason jars to do this in an oven set to a temperature of 250 F. The pressure rating on a 16 oz mason jar according to various sources is about 30 - 40 psi. What is the appropriate amount of input material that should be used in the sealed mason jar to fully convert the THCa to THC?

PV = nRT

P = pressure = 30 psi or 2.04 atm
V = volume = 16 oz or 0.47 L
n = moles = unknown
R = ideal gas constant = 0.08206 atmL/molek
T = temperature = 250 F or 394.3 K

Plug it all in…

PV = nRT
n = PV/RT
n = [(2.04 atm)(0.47 L)] / [(0.08206 atmL/molK)(394.3 K)]
n = 0.029632 moles CO2

@cyclopath

One mol thca == 1 mol co2

0.029632 moles CO2 = 0.029632 moles THCa

0.029632 moles THCa * 358 g/mol THCa = 10.6 g THCa

Using a 16 oz jar @ 250 F to decarb cannabis oil under pressure, you can use 10.6 g cannabis oil (abiding by the 30 psi pressure rating of the mason jar) or all the way up to 14.1 g (using the 40 psi pressure rating).

I don’t recommend glass…and folks have linked to web based calculators to make this easy (damn gatekeepers)
