hello!

ahh swim is up to his third extraction using an stb (a/b had previously resulted in a runny weak extract...) and swim ran into a problem, dissapearing invisible solvent... after mixing all the liquid was one amorphous black substance... overnight it did seperate into a different emulsion to the ones id seen (cloudy with no bubbly part) and a solvent layer ontop of the black liquid, however even with the emulsion added to the amount of solvent in the top layer there was a LARGE discrepancy from the amount of solvent originally added to extract. well this was very confusing ! where had so much solvent gone? well swim was siphoning off the solvent that was apparently and ended up transfering liquid from a bottle into a container to ease the process, had poured off ALL of the solvent and emulsion present in the bottle , placed in back down and out of nowhere hundreds of mls of solvent suddenly reappears, with little to no emulsion present! :shock:

swim plans to shortly experiment with more of this pouring (agitation and some shaking had previously been used to uncover missing solvent with no success) ... this all swim found confusing right? where was the solvent trapped why was it not in emulsion? or was emulsion invisible? dont know , perhaps someone does?

was trying to post in another forumn i see that i am only allowed to post in the nursery? when will this change? do i have to have so many posts or somesuch to achieve full membership or must i write essays??

p.s does anyone know the ratio of sodium carbonate or bicarb to water needed to achieve a ph of 9-10... my ph meter just died on me ...

another question on the subject of polar washes? ... why is it better to use sodium carb or bicarb to raise the ph of water than sodium hydroxide... when you would end use using less right?
 
:cry: swim sits in his room crying, seems noone loves me :cry:

ph meter was broken $15 wasted dollars on batteries now stuck for a wash...

more dissapeared solvent reappearing at the speed of lightning ... anyone know about these invisible emulsions that are out of sight ? stuff must of been thrown out under the illusion nothing was there

Show good attitude you will be enable with the full capablities of a member.

Sodium carb or bi carb cnt remeber which one, is used to WASH the solvent, and NOT to basify. Sodium Hydroxide is to basify, that is NaOH not NaCO somthing or another.
By washing with NaCO what ever Co3 mayb, i forget, it pulls out any NaOH in the solv, you will see thin blade like crystals come out, from swim exp any way.

You add mim to your water and add enuff basifiying agent till its jet black.

hope soem of this helps
 
Sodium hydroxide for basifying-till the liquids black then add a little more for good measure.

Sodium carbonate aka washing soda for the wash-a small pinch added to water is all you need-I wouldnt worry to much about the pH.

If you have got sodium bicarbonate aka baking soda, have a look at the Wiki-Im sure theres info there on converting this to the carbonate salt.:)
 
Please, add more information when asking questions.

As others have questioned, are you using sodium bicarbonate or carbonate for an STB? It wont work, you have to use sodium hydroxide.

Also, how much bark are you extracting, how much water was added, and how much base ? Appart from the obvious problem if you really are not using NaOH, other issues could be that there's too little water, therefore your naphtha is getting trapped in the thick liquid.

Another mistake I already see you are making is shaking. DO NOT SHAKE! Stir it in circular motions or turn the container end over end (if its a container that closes well and has a non-reactive lid).

As for why using sodium carbonate for washes and not sodium hydroxide, its because you want to get rid of possible sodium hydroxide traces (and other polar impurities) that might have come across in the separation. If you wash with lye water, then there still might be lye in your final product, so its sort of beating the purpouse. Of course, if you use just a tiny tiny tiny amount of lye for making a very dilute lye solution, it would get rid of polar impurities and guarantee that at least most lye is out. But isnt it much better to waash with a weaker and food-safe base (considering you can make sodium carb from sodium bicarb easily) than to keep using lye which you want to get rid of?

Lastly, as for the nursery, yes you can only post here for now, as you can read in the welcome message thread. This is the solution we found to prevent badly intended people and trolls from entering the forum. You just have to keep posting a bit and you'll get promoted soon enough, dont worry. You can even start threads refering to other threads that you cant post in yet. Writting an introduction essay will definitely help you getting promoted. As you can read the other essays here, it doesnt necessarily have to be anything too elaborate, just tell us a bit about yourself, your thoughts on the world/philosophy/whatever, your psychedelic / extraction experiences, etc.

See you around!
 
thanks mate,

Yes ahh swim was extracting with 2/3 ratio by wieght of NaOH to wattle bark.
Sorry if the question was vague was intending to find out more about the
blackness problem with the latest extraction which had seemed quite different
to the emulsion issues encountered previously. And as to wether the discrepancy
a visible top layer with solvent added is something that people know about, had
not read anything to the point.

I also have another question! done a quick search no clear results...

What is the best form of ascorbic acid to use in an acid soak/cook, swim has
calcium ascorbate as a powder? does it matter if planning to use the C to make
clear crystals?
