a study published in the journal American Chemical Society identified the skunk-like or sulfuric aromas that you may be noticing as coming from a family of seven scent-producing molecules called “volatile sulfur compounds” (VSCs).
VSCs are part of a family of volatile organic compounds which also includes the terpenes and terpenoids.

Firstly carbon scrub the material. Then proceed with the below.
This is for a series of around 15-18 total washes. If you’re good at lle, you won’t loose a lot of material.
3-5% bleach by volume on a 1:1 lle solution : sulphur tainted oil in solvent, wash this for 45 minutes then separate and discard aqueous layer, then wash with brine, you’ll have to buffer with brine inbetween each wash helping elude all the nasty compounds more efficiently. swing high ph first then buffer with brine, then bleach, then buffer with brine, then switch between acidic & alakaline ph till your satisfied with the look/aromatics, then finish off with neutral washes to balance out while checking of course always ending up around ph of 6-7. Proceed with discard of final aqueous layer, filter solution off with sulfate & remove all solids/ residual moisture, recover solvent & then run first pass with copper scrubbers in the spd head.

pump it thru a copper coil. a big ol worm
I just soaked the pennies in pure ethanol. No change occured. So now I have some botanical terpenes which I’ll add to the ethanol to see if the pennies will darken in color.
Top row: ethanol with BHO
Bottom row: pure ethanol
My pennies look nothing like yours. Do you remember the pennies to oil ratio?
Like .9g of oil in 5mL ethanol. Clean the penny with vinegar first
I did clean them in water+citric acid. I’ll wait until tomorrow to see what happens with them in ethanol+ botanical terpenes. If not I’m just going to buy some copper tubing on Monday. Thank you
are people seriously still using Sulphur on their plants… let alone extraction it hahaha thats bunk!!
I can definitely confirm that at least some farmers are using Sulfur on their plants. We extracted a large batch of biomass that ended up having significant Sulfur levels.
Hard to tell with most sugars until you dab them, the terp fraction (HTE) usually will have an off nose to it and the taste is terrible. We even decarbed a small quantity of one strain of THCa into diamonds and when you open the jar, the smell will almost curl your stomach.
Ordered some of the scrubbies to at least try and remediate the HTE fractions. Thanks for the heads up about those c0dean.

iv extracted plenty of sulphury biomass but not in like 5 years haha we always threw out the extract and made the biomass supplier pay for a new lot of gas plus cleaning time

So after 48h In ethanol with botanical terpenes there’s no change in the appearance of the pennies.
Top: ethanol+BHO after 24h
Middle: 48h botanical terpenes
Bottom: 4 days in water+ citric acid. They should look like the ones from the middle row after a bit of scrubbing with a kitchen scrubber.
I’m guessing I do have some contamination. So my best guess is to just buy some copper tubing. As to avoid any other metal that my be in the pennies.

I’m gonna buy some silver first
Silver will definitely tarnish in the presence of sulphur. Some of the newer bullion is coated to prevent tarnish, but I don’t really know which other than newer maples leaves. Maybe you’ll get lucky and wind up with a neat rainbow toned coin, or better yet, sulphur free dabs.

heeeeeellllp!!!
Identical problem happened to us just recently
It’s a total dick move by the farmer that knew that when he sold us product
Problem is it was fresh frozen and was used in bho extraction … we didn’t get to it right away took a while for my costumer to figure out why the hell the smell was rotten …
they thought it was their hardware
I can’t begin to tell you how it ruined our relationship with several clients…
Luckily it was a licensed deal and I raised absolute hell!!!

After all it’s not sulfur. Smells rubbery skunk. Now that I had the chance to smell the sulfur I can note the difference. I guess the smell comes from terps after all.
My silver came in and after 70 hours in 100ml Ethanol and 10gr. Of BHO I saw no change to the surface of silver.
As a control I bought some sulfur and added about 0.4gr to 50ml ethanol.
I placed the silver in the solution and after 5 min you could see the silver going yellow.
Straight out of plastic:
After 70hours in 100ml ethanol+10gr BHO
After 3 hours in 50ml ethanol with 0.4 gr sulfur. As you can see sulfur is not very soluble in ethanol.
I’m going to leave the silver in there for a few days to see if it will remove all the sulfur. Not very probable.

Your silver is now contaminated. Send it to me for proper disposal.
Happy to hear you just had some funky skunky instead of sulphur dabs!
