Identifying crystal formation of meth adulterants after acetone evaporated after wash

[CanisThief]

So this is my first post here.
I hope its in the right place.

Ok so swim washed some dope with acetone (didn't dry with epsom salts)
Well swim was left with very clean product.

But swims question is.

Is there anyway that he can identify that what dissolved?
He put the acetone in a plate to evaporate and a lot of crystals formed.

All swim wants to know is what he was left with. And if swim lost some meth during the acetone wash and if he can salvage it?

If you didn't dry it, then its probably your meth...

Honestly, if you've already got shards and they smoke normally then I wouldn't bother doing this. Only if you know or highly suspect that half of the crystals(as in some crystals are meth, some aren't, not the composition of each crystal) in your meth aren't actually meth.

You needed to dry both your meth in the oven (on a low setting), and make the acetone anhydrous. As said, most of what you've recrystallised is almost certainly meth.

Btw, please talk first person, not 'swim' - it's hard to read.
