My first reaction: 500g of Fumaric acid is a lot! With 500g of Fumaric acid you can convert about 1.5kg of DMT to DMT-Fumarate. If you look on ebay you can find food grade Fumaric acid for about 10-12 dollars per 250g and with that you can still convert about 750g of DMT.

If you look at vinegar then you can get about 20 liters of vinegar for the same price. Vinegar however contains about 5% Acetic acid. So with that 20 liters you have about liter of Acetic acid.

I'm not sure how much Acetic acid you need to convert one gram of DMT but remember that Fumaric acid bonds to two DMT molecules due to the Fumaric acid having a specially formed molecule that Acetic acid doesn't have.

This all means that cost wise the Vinegar might still be better, but it will only be with a factor of about 2-3.

If we then continue to calculate the cost of salting one gram of DMT to Fumaric acid:

* 12 dollars for the Fumaric acid;

* 9 dollars for the shipping costs;

* TOTAL: 21 dollar

21 dollar for 750g of DMT, makes for about 28 cents to salt one gram of DMT. If you consider the other ingredients needed for an extraction like bark and lye then this should not be the make or break cost factor.
