Put up the pictures. There are different wax types, butane extracted, CO2 extracted, shatter, peanut butter, I think amber glass is considered wax in some places (or at least my shop does).
A hallmark of "homemade" or amateur wax is bubbles or other impurities that werent properly purged from the finished product. Bubbles often indicate residual butane in the wax, and smoking butane cant be good.
I dont know if its just my medical shops but the best wax IMO is the stuff that looks like straight earwax.
