First, I would like to humbly thank the brilliant mind who had the.presence of mind to develop the q21q21 tek for mimosa. I've never seen more beautiful flowery spidery xtals! However I had some surplus acacia confusa rb and I decided to try my hand at modding the above said tek for just that reason. Basically what I did was the q21 acid wash step, but I added an experimental defat step right after that. I added naptha at a rate of 100ml /40g acrb..test run ya know? And I let that mingle with the Acrb mud for about 3 days all the while stirring and agitating a few times per day. The reason I did this is because unlike an a/b Acrb tek liquid to liquid this time I noticed that there was no discernable change in the viscosity or composition of the mud (Acrb acid soup)...ie no defat bubbles no color change of defat solvent initially. So it sat and was stirred for the 3 or so days.
After that time however I noticed a very fine fragile and sensitive membrane on the top of the Acrb mud soup...it looked like oil on water.. get it now? I poured off and collected this funky layer 4 additional times after agitating again and again and was finally left with.the mud. So from there I just followed the q21 tek pretty much except that I allowed my lime/base soup to settle in naptha for a couple of days at room temp before pulling.
The result was not gold goo as I was used to when doing other a/b tens of max ion or vovins etc...but oddly a clear goo on the bottom of my dish which scraped up to become white xtals/white semen-looking goo after being warmed and also white/translucent flowery xtals all along the upper rim of my dish. So believe it or not...try it for yourself or don't. That's what I got...and smoalked and blasted off with using only matchhead sized amounts for the past few days. And before anybody blasts me for using the q21 analogy or whatever remember...this is a psychedelic forum and I in no way take credit or am affiliated with the genius who first discovered that gem of a tek. It's just the basis for my own experiment and it word very well. Peace love and happy travels folks. Sorry if this already exists somewhere on the nexus but I just wanted to toss my hat into the indole ring haha! I will post pics very soon also...

I have been meaning to write this up here but didn't want to start a new thread, here seems appropriate. I follow tek II and use a slow cooker. I achieve apple crisp consistency by heating it on low for an hour or so. To heat the naptha I simply slowly warm it up in the cooker. Sometimes it can get too hot imo, that's when I pull yellow or even brown oils and on my most recent extraction a peculiar transparent oil id not seen before as per your description that scraped up as white, floral scented powder and is getting sampled tonight!

Recently both my coffee grinder and food processor packed in: they lasted a year of MHRB each...not bad going but left me in ye lurch. I figured my shredded MHRB would still yield after a few hours soak in vinegar. The only vinegar I could procure at the time was Sainsbury's White Wine Vinegar: 6% acidity. I couldn't find any advice for or against it apart from its inclusion on the wiki so thought 'wine not' and dribbled it in. Once the water was in it looked fantastically gory and I felt cautiously optimistic. After adding the calcium hydroxide it looked like a suitable yet fibrous bed for the Newport naptha. I would stir, then wait for the sizzle of naptha then compress the bark beneath the naptha with a potato masher so that it was completely submerged. Then after a whole break it apart with a chopstick, repeat and pull. 6 pulls on 250g shredded, hand broken MHRB yielded 5.32g mostly white spice, a little over 2%, not at all unheard of for q21 but one of the best yields I've had and my current extraction is doing nearly as well, 3g on 4th pull I hypothesis the extra one percent acidity white wine vinegar, extended soak time and the potato masher submersion break down most of the cell walls and wonder what kind of yields I would be getting with my new approach and equipment if I started to powder my bark again!

White wine vinegar...WINE not?!

And don't fear if your blender or coffee grinder breaks, this has worked 3 times for me now with no impulse to visit Argos again any time soon! As somewhat of a Luddite I shall grind my valerian in a pestle and mortar

Many many thanks to q21q21 for his super efficient, clean spice extraction tek that delights me more every time!

Was there any specific question there or just sharing the results?

Doesnt seem like there' s anything wrong, you got an oil which eventually crystallizes, and you can blast off from it.. Sounds good to me
