Probably one of thousands of boring extraction write-ups.....but we're here to share right.

I chose to use q21q21 tek2 for this. 5% acetic acid, Calcium Hydroxide, Zippo fluid (Couldn't get Naptha)

Obtained shredded MRHB.

100g MRHB for first attempt.

I tried to powder the MRHB using an electric coffee grinder retrieved from the back of my cupboard.

It would not reduce the MRHB completely to powder......it left some fine mass of fibrous root....though it was very fine.
I nearly quit at this point.

(p.s. do wear a mask....I didn't and suffered for it)

Because I was generating some powdered MRHB, I decided to seive what I had to seperate root fibre. I discovered that I actually had 80 grms of very fine powder!

Ground a little more to acheive 100 grms.

Worked through the tek.
Used a consistency of thick porridge in a perspex mixing bowl.

Limed it and left for 8 hours.

Transferred mix to a perspex mixing bowl.....warmed in the sink......150 mls zippo fluid added.
(Tek said 100 mls of naptha).....but surface area in the bowl was large.....hence I tried 150 mls.

Into a perspex flat dish and into the freezer.

Crystal appearing after a couple of hours.

Left in the fridge overnight.

Lots of crystals the next morning.

Removed solvent and evaporated dried the dish for a couple of hours.

Scraped up the first lot......the volume surprised me.

Weighed and got 400mg on the first pull.

Pulling for a second time as I type this.

Will see if I can manage to attach pictures.

Will update the subsequent pulls when completed.

All the best,

Airpig.

Nicely done - it looks pretty clean. 0.4% from a first pull suggests you should get a bit more in the next pulls.

It may be that you end up with a significant portion of your yield trapped in your naphtha (depending on the composition of the naphtha and the temperature of your freezer). It would be worth it, at the end of all the pulls and after the last freeze precipitation has been completed, to wash the remaining naphtha with some vinegar water. Then put the vinegar water through a final base/naphtha pulls/freeze precipitate using a much smaller total volume of naphtha.

Thanks for your contructive help. I'll have a look around and see if I can find a procedure for the vinegar wash.......details as I'm not that bright.

Just done a second pull. Didn't look as much (though larger crystal clusters).....400mg again.

There was definitely still product suspended in the solvent. Could be seen when decanting.

Last night I added another 20gms or so of calcium hydroxide and mixed in to the base.
Going off piste I know.....but thought it might revitalise things (I have no idea what I'm doing 🤣

Third pull done and in the freezer.

Will update.

I have some Fiddes Naptha Thinners heading my way. Hopefully it will be a better thing to use in future.

Couple of pics of second pull added.

This shouldn't do any harm and may help sometimes. The main thing is that the paste has sufficient moisture to retain a cookie dough consistency and won't release any dry particles of lime into the naphtha. Getting lime dust in the naphtha is a bit of a pain.

Maybe this DMT Extraction Overview will help you to get a better grasp of what's going on in an extraction. A good understanding of these principles is what helps to guide one beyond the simple following a recipe and into a more robust approach.

Thanks again for your guidance dfz.
Will read the data.

Third pull netted 240mgs.

SWIM would probably call it quits there......and take a 1% yield for a first attempt.

Plenty for SWIM to work with.

Thank you again....appreciated.
