Depends on the hash oil you want to make.
Butane Honey Oil(BHO) is more pure, but hazardous(combustible)
Hash Oil(the black stuff) is made with Denatured, or ISO Alchohol(I use denatured for better evap, and cost)
Or, you can dry sieve.(not called for in this case)
youtube it. That's what I did. Also my dad taught me about using denatured alcohol. It's available usually at home depot by the gallon for about 16-20 bux.
Oh, and make sure it is dried completely, and ground up good b4 you start, or it will be even shittier than it's already going to be.
Don't be discouraged if it's only a small bit.
