I did another extraction of 150g MHRB with this tek, i mixed in straight vinegar until it was a gooey mix, not too watery but just enough for vinegar to spread, i only left it 15-30minutes & didn't mix that much, i kept it in a nice warm water bath at the beggining & tested with PH strip which went red.
Then i added 90g calcium hydroxide, it went very dry as the mix was already quite dry from the vinegar step, but i was concerned this was not enough CaOH to basify all of the mix so i added some splashes of water which made me need to add lots more calcium hydroxide to dry out the mix, probably 250-300g total, way more than necessary.
I then pulled with 300-400ml warm Naphtha, a nice juicy pull

and left it on a gentle heater & stirred thoroughly over 45 minutes or so, i wasn't concerned with losing Naphtha in the mix as it was such a big pull. I think if you use Naphtha in this tek that it would be a good idea to have a nice amount of Naphtha on hand that can be recycled 3/4 times and expect to lose some along the way.
If you wanted to do smaller pulls it would be best to do very small precise/dry extractions so you don't have to actually mix the Naphtha in at all, just warm it & run it/swish it over a dry basified MHRB mix over & over.... it could be interesting to make a really dry mix that was almost powdery then just swish around warm solvent in it/filter out the bits with a coffee filter.
Anyway, i left this first pull in freezer overnight and the glass dish is now covered all over like that picture i posted a few pages up of a beaker :shock: and it has
lots of floaties too.
I learned from all this that i need to buy a PH meter so i can know 100% whats going on in the mix, as i don't want to keep on using excess CaOH, it's nice to add
just enough vinegar so it's a thick goo but wet enough for vinegar to access all the bark, then in this case one would only need minimal calcium hydroxide as the mix is already quite thick/dry, it could be much better to add CaOH until your PH is on point.
This is so fun.
