Bleaching earth

So with bentonite it is possible to adjust the pH of your product? Means: If I have a disbalance (pH) in my product i can manipulate it with different types of bentonite depending on their different pH?

Correct. Furthermore, because T41(pH 3) and MagsilPR(pH 9) are meant to be used together…you can neutralize during processing.

What would tou suggest dor color remediation with out alot of isomerizarion ro d8. Either in rhe flask or as nust a dimteation aid. Love all tour peoducts and rhe knowledge tou fibe out is priceless. Thank you

Remember that your sources of color vary (chlorophyll, phenol, oxidized terps, oxidized lipids, etc). For chlorophyll and lipids T5 and carbon works great, alumina helps too. A tight fractional distillation helps with phenol and oxidized terps.

An important lesson on isomerization is that it is a redox reaction for THC and so a function of heat and energy transfer (pH). We only ever advise scrubbing at about 90c max, and avoid excessive acidity. Putting absorbent in the flask makes them too effective, so you would expect isomerization to a certain extent without reducing absorbent load.

Note: I try to be as intelligent as possible but there may be variables in your process that makes your results differ from what I’m saying.

After doing some more research and reading that some bentonite clays are known to contain lead, I think it’s best to just get your bleaching clay from a trusted source like carbon chemistry.

That reminds me…T5 is also engineered for heavy metal remediation. We have a client in another industry that uses it for mercury and arsenic remediation during prep phase.

That’s great you’ve produced a product that is mixed and Rtu for processing. I’ve used a mix that seemed to work well for me as far as removing color. The mix I used goes as follows;
Bentonite clay 9%
Celite 545 3%
Activated carbon 6%

I’d love to check out your mix though. I’ll be placing an order :call_me_hand:t2:

can you provide me with the info to procure the products you provide? ty my friend

Anyone have information on the particle size of T5? I have 5 micron screens currently, will that be enough to prevent any clay from getting through? Thanks.

Yes
Silica60 is the only powder where I am in doubt

It won’t be enough to catch everything right away. There will be passthrough as the puck settles. I suggest running clean ethanol (or solvent in use) through until there is no more passthrough. I used to use a coffee filter (nominal 20um) to allow the puck to be formed. As the puck (or cake as some say) settles, it develops a deeper, more refined matrix that will be far finer than whatever you have it placed on, effectively trapping itself.

Edit: If you have mixed the magic dirt with your tincture, crude, or other media, I suggest two passes through the same filter to ensure there is no passthrough lingering from the early stages of filtration.

Up to now by placing celite as last powder or calcinated quartz
I have not have powders treu
But then again I have the 0.2um filter
Also :wink:

@Roguelab, are you using filter papers or a reusable one? I know that I have had AC pass through 0.2um time and time again, but the T5 catches it every time!

Filter paper and ss disks
And the 0.2um filter cartridge
This is for crc so no AC in my stack

@Roguelab, as you know, I am fond of the AC/T5 combo for ethanol CRC. I’m curious how long the sintered disks at 0.2um work for at their rated level of filtration. Filter papers get to be so damn expensive! Haha (not that you can out a price on putting out clean products to market!)

The coffee filter still does most filter needs in my shop😁
The 0.2um is a cartridge type and amazingly keeps flowing for quit some time now the sinterd I still place paper over before any powder to prevent
Clogging
My next project is a seperate solvent crc unit for butane /propane
With a very large sintered cartridge filter and 60% of most powders
Mixed in the pressure vessel
Let them drop and siphon of the solvent
See if that gets me any where :grin:

I noticed on my bag of silica it has its mesh size listed at 200-400 mesh. The information I found is that 200 mesh is equivalent to 74 micron. Seems 5 micron screen gasket would hold it back no problem.
Any thoughts?

This is due to the bentonite removing the negative charges on the surface of the particles of activated carbon. This has the effect of causing tiny particles to stick to each other rather than repel each other. This makes it so simple filtration can be used to remove AC.

t5 for the win. Have you had a chance to try b80?

I have not. T5 and AC worked so well, I never needed to do anything different. (And I had no funding or time for experimentation)
