Wax Question?

So my buddy got this the stuff you see in the photo.... Before he heated it down on a skillet, it was more a hard butter texture..... Why is it this color? Is this full of contaminants ha.... Serious question tho....


Thanks for the help!!!!!

Doesn't look terrible but definetly some contaminants and unwanteds in there. How does it taste? Does it leave a residue in the bowl or nail and if you light with it a regular lighter on your dabber will it hold a flame. Look into winterizing and also I think if you re-heat and re-purge it would help but I'm guessing you're not using a vac. I looked into the price and effort required to get all that set up and decided to stay away from solvent extraction's in general, stick to Rozen press and bubble hash. I am in the process of winterizing my first unsuccessful BHO attempt that came out looking pretty much like that and was very sappy and tasted of butane and gave me a major migraine the next day
