Hi... i have already read the ok to use thread but im concerned about other thing ...

i was reusing epsom salt and some of it looks like it got burnt... i used it to dry solvent anyway and it gave the solvent a brownish tint, I was using toluene.... i decided to use it anyway and extracted with it... i did not seem to care at first because i was able to salt crystal clear fumarates off it with fasa.... some pulls were pure white others orangeish and pale yellowish...

Now i am reading about sulfur trioxide being released when epsom salt burnts... im afraid my product can have trioxide contamination on it... because it reacts violently with water to form sulphuric acid so its not ok to smoke...

i wonder if i can make something to clean this??? i already mixed fumarates with water with no visible reaction other than the fumarates dissolving... i added carb water to yield orangeish crystals, that melted when i cleaned with water...

tried drying the goo but it did not dry.. so i pulled with iso and placed on a glass dish... with a fan to dry...

it formed orange DMT rocks that im kinda not to eager to use becausse of the fear of the sulfur trioxide...

is there a way that could clean my spice from this potential contaminant??? cant find the solubility of SO3 in polars and nonpolars... only solubility in water

Magnesium sulfate decomposes at 1124° C (2055° F), sulfur trioxide boils at 45° C.
Your almost certainly safe just based on that. If you heated it in a closed container hot enough to melt steel you could just bake it in the oven to be double safe I suppose.

Most likely what happened was a contaminant decomposed. I had that happen once

then if its a decomposed contaminant it is safe to say that such contaminant is still present even if i did a tone wash and then water wash... making such spice not suitable for experimenting

forgot to post the product pics.... very orange spice from FASA with tol... never seen rocks like those even on pics... are they normal?

could a possible contaminant from the darkened burnt epsom toluene be washed away with just re-X or better by performing another A/B and then FASA, then water carb freebasing?

What did you dry with the magnesium sulphate the first time around? If it was acetone then you'll have formed a small amount of condensation products which will have charred to produce your contaminants.

Recrystallize.
