As many of you know, a clean plate test is the ultimate test of any solvent, and should be done when testing a new brand of solvent. For butane, it is even more important. Many brands are manufactured by the same company, and different batches from the same brand can often vary in purity. Moreover, butane frequently has toxic industrial lubricants added to the butane to help with the workings of refillable lighters. For this reason, if you are making BHO, you must test every batch of butane you purchase, even if its from a trusted brand!
The clean plate test is very simple, and 100% effective in determining if there are any contaminants in your solvent that will not evaporate and remain in your oil. Just take a plate, pour a small amount of solvent into it, and leave it outdoors in the sun or on a double boiler until everything that can evaporate off does so. If you see a greasy puddle where the solvent was, or if you run your finger across the plate and feel any slickness, your solvent is impure. With butane, just press the nozzle agaisnt the plate upside down so a bit puddles in the middle. Because of the cold, it will pull h20 from the atmosphere, wait until these condensation droplets evaporate and the plate is room temp before you run your finger across. A good sniff of the plate can determine if there are mercaptans, which are not oil based and thus dont feel greasy; they are added to butane so you can smell leaks, but if it gets into your hash oil it is the foulest smelling substance and will ruin your batch.
