I have a new vacuum pump.

I just turned it on after going through my normal processing and see lots of gas bubbles.
I wonder if any of you know, is there an optimum temperature for the purge?

Just below flash point where the vapor pressure is highest if speed is of the essence.

Speed is less important than not screwing it up.
It is a 3 cfm pump so I was thinking of running it a couple of hours at about 90 degrees.

If you can do 120 for a while you should try to make honeycomb.

You should be good up to that for a couple hours just to purge also.

The hotplate I found sucks. I can't control the low end of the temperature scale very well and I worry about over cooking.

If you can get grain alcohol you can purge in liquid. It's basically how I do it.

I don't really understand the subtlelties between shatter and wax and honeycomb.
A buddy grabbed me some pharmecuetical grade shatter from a compassion center and it was great.
That is what I am trying to duplicate.
Is it just a matter of time in the vacuum chamber that separates one from the other?

The way I have found of making shatter is taking the grain alcohol and you do small pours and let them dry before pouring the next little bit. If you pour it all at once you get more like a standard BHO. Clear but gooey. Using a liquid lets you get it cold and filter it again removing a lot of wax and helps make the end product a little harder.

The way I found to make honeycomb is to simply cook your mostly purged BHO at 115 or so until its solid. You can skip the vacuum with this or the liquid method. This to me looks like the easiest extract to handle. It basically looks and handles like sugar cookie.

So far all I have made is BHO first I take my mostly purged BHO add it to alcohol. Freeze and filter it again (winterize). Then I pour it into my dish to evaporate slowly. Last time I just poured it all at once. The time before i kind of did the small pour thing and it does come out like shatter.

This is what I do, modified for me.

This shows you how to make honeycomb. You can probably skip the first 9 min or so cuz he's just doing the extract. And I'm sorry, he does vacuum purge before he makes it into honeycomb. I plan on trying this when I find a good low temp hot plate.

hey dick

whats your chamber?
homemade or store bought?

25 years ago i did moldmaking with this two part stuff
flexable when dry

had a square plate about 14 inches square
and this giant domed glass to place over it

must have been 2 feet tall
