So the neighbours little Bufo Alvarius wanted to try this approach to see if it could maximize yield.
200 MHRB used.
The idea he told me was to first pulverize the bark using a blender and some distilled water. Then pour this in a pot and heat to a boil. After that let it cool to room temp then in to the freezer over night.
Next letting this thaw and then put it in an acid bath boiling this for around 9 hours with 3 cycles of water and acid.
After this combining the liquids and filter them some times through different filters to get a clean liquid in the end. Let this be in the fridge for a while for more gunk settle to the bottom then decant and filter once more. After this boiling down the liquid to around 1 liter.
This liquid is then poured into a 5 liter vessel while the MHRB “clay” is put in another 5 liter vessel and topped up with distilled water LYE and salt. The same for the other vessel as well.
The first work involves only the vessel with the clean liquid. Pulling with Hexane, freeze, dry and collect. When this is not pulling any more “magic” then the work with the other vessel begins.
This is done without heat except for the last pulls where the vessel is put in a hot tap water bath.
He told me that so far only with the first vessel he is nearly up to a yield of 2% of fluffy white crystals and some more yellow but still pretty fluffy ones.
If you want to try this tek there is some safety precautions to be aware of.
LYE/NaOH - When working with this always wear safety equipment such as gloves and goggles, as well breathing mask. Always add this to water not the otherway around.
Hexane - use breathing mask when working with this. (Hexane is neurotoxic - avoid prolonged exposure.)
Separating layers - Be careful not to get any LYE in you solvent when pulling. If you do there is ways to go: either make a mix of bicarbonate and distilled water and add to the solvent mix and separate. Or you can simply transfer the solvent with the lye spill into a smaller narrow vessel when you separate this again.
Be also careful if using heat, the vessels should be warm but at a temperature good for touching them with you hand.
Freezing - make good wrap of plastic film around your pyrex otherwise the solvent easily escape and contaminate your freezer.
When ready to evaporate be quick by pouring of the solvent and fan dry the dishes with the goodies. If you are to slow they will melt into the remaining solvent and make a mess.
Whn you have scraped up you crystals there is ways to purify them with an RE-X process. When using this approach at least in my sense there is no need. The first pulls with the "liquid only" vessel will bring you very pure and fluffy crystals.
Also it is worth to mention that it is even difficult to get emulsion in this one. You can shake mix in a violent way and still the separation is pretty quick and clean.
1. 200 MHRB blended with distilled H2O
2. Make a boil then freeze and thaw.
3. Acid cook with distilled water and lemon acid ph 3-4, 3 cycles*3 hours. Filter and boil down to about a liter then pour in your extraction vessel (5 liter). Take the MHRB dough and put in your other vessel.
4. Make a mix of 200gr of salt and 200gr of LYE mixed in distilled H20.
5. Pour this equally into the 2 vessels and top up with distilled water(leave room for solvent).
6. Start mixing solvent 100ml into the vessel with the clean liquid(leaving the other vessel of mix to work during the period of time your are pulling).
7. Mix 100ml Hexane stir/mix 1-2min then let separate, repeat 3 times then pull, freeze over night decant and collect. This was done 9 times.
8. Now start with the other vessel with the same approach.
The frog promised me to report back when he was done to see what the final total yield is.
