Hey 1ce I'm almost done gathering all the bits now. Just wondering whether this would be okay for use as the 'wine jug' in marsofold te; Glass Demijohn

That's work perfectly! It'll also make it easier to pull off your solvent.

Haha, well thats encouraging ! Thanks for all your help 1ce.

You got it man, best of luck on your harvest!

Anyone got any other specific ratios of vinegar:water and lye:water for 1lb of mh ?

I use for myself, 10ml water per gram of bark, with 10% sodium hydroxide by weight for a stb. I do A/B extractions these days so I do 5% NaOH.

Hey 1ce, you don't seem to mind answering my questions so I've got a couple more things to ask before i start this weekend.

1. Should I do separate naptha pulls ? If so, hot should be better right ?
2. All these quantities in marsofold tek are in american litres, not imperial (english), right ?

I'm not sure what the marsefold tek uses. All extractions are basically the same thing. Metric system will be alot easier though.

It really depends on the solvent you use. I do a very small heated naptha wash during the acidic phase, and extract with 1 pull of chloroform below room temp.

Using naptha I would heat the whole thing (hot/warm water) and mix very thoroughly. Allow the layers to separate out and mix again and again. Be sure to relieve the pressure of your mixing vessel, I can get away with heating my solvent far easier because everything vents out through a condenser and refluxes back into my mixing flask.

Using an enclosed bottle the pressure inside will build, so be sure to vent it every few rolls or shakes. I'd hold the temp at 50-55C. This is where I've noticed alot of oil saturation in naptha pulls, any higher will just serve to create an excess of vapor.

For your first pull I'd use 1ml per 1g of bark you used, I typically use half that amount in my extractions, 1ml per 2g bark used. But I'd only recomend that if you strain the bark out quite well or else you'll have suspended bark particles in your tiny bit of solvent.

You will be pulling off heaps of oil so be sure to cool it so excess oils drop out of the solvent. I'll also wash it a couple times with cool distilled water while the naptha is warm. This helps to remove oils/base solution. You'll probably notice thensolvrnt turn an instant neon color, this is fine. The cool water in the hyper saturated solvent causes some particles to crystalize, and this refracts light giving off the odd color.

Place it enclosed, inside your freezer. You will have a wonderful harvest soon, my friend.

Hey 1ce,

Finally got it done ! Just left in the freezer now for a few days, can already see a load of small crystal on the bottom after a couple hours, I will let you know how it gets on in a few days ! Everything seemed to go smoothly, I just hope the final product is up to scratch.

Thanks for all the help !

Hahaha I'm certain it's mind blowing 1-2 days is fine for a freeze precip. Thr only advzntage to a long evap is letting it start from room temp with a slow, partisl evaporation.
