1: Are milk jugs really safe to use? If so why is it that this is the first time Ive seen it used in a tek because its so cheap and easy.
2: Have you ever tried to do a sodium carbonate wash or are the re-crystallizations enough to get it clean?
Thanks for being awesome. 8)
Gir said:Pandora said:The double decanting is a great idea. He think it should be mentioned, because turkey basters are hard to use and SWIMs wife is pro and all....but still gets some shite in there. SWIM likes to use syringes towards the end of the second decant, to get most of the naptha from the rest of the basified shtuff at the bottom.
and those steps are SERIOUSLY crucial, It looks as if SWIM is getting almost 2x his last yeild of 0.8%, one martini glass looks like a FASI precip :twisted: the slow evap is complete, about 45% of the volume (it was sitting next to his a/C unit that gets kind of hot even though it broke :evil:, so it went overnight pretty fast. Just stuck it in the fridge. then gonna stick it in the freezer in ~6 hours.. He still doesnt know what the fridge has to do with helping evaporation, but its a good experiment anyways.

I haven't found turkey basters here in .nl. But I used a 2ml syringe. I ordered a 5ml one to do it all quicker.
But as for the extra decanting, I ordered some borosilicate tall glassworks. But for small amounts test tubes are excellent. I don't have true lab tubes. But once I bought vanilla sticks and they came in a similar tube. Any solution containing lye traces is very easily decanted away. Whats is left can still go back in the...the stock I suppose.
I gotta find me a supplier in .nl thats ells to private persons. I found some businesses that sell to schools. The borosilicate glasswares are easier to get. I will make a post in the appropriate section.

I'm still learning about extraction, Is this essentially the Noman tek ?
Electric Kool-Aid said:You probably didn't let it dry enough in the freezer and it has solvent left in it.
Put some naphtha with the melted spice and place it back in the freezer, then after 12-24 hours you can decant and flip your jar / tray over and keep it in the freezer for like an hour.
Then when you take out the container, you want to re-seal it and bring it to room temperature for about 20 minutes. The covered container to room temp is important because spice can get condensation from cold to room temp, then you have wet spice. Plus if you pulled spice out before drying in the freezer, then there is leftover solvent that is still left in the container when warmed turns the spice back to liquid.
