Generally speaking, all forms of heroin give off a vinegary, acidic smell when smoked. However, due to the different types of heroin - and the fact that batches are produced in different geographical regions - each tends to have a different odor. In its pure form, like China White, heroin puts off the least detectable stench.

Parting is a process by which gold is purified to a commercially-tradeable standard, typically ≥>99.5%. Removal of silver is of particular interest since the two metals often co-purify. The standard procedure is based on the Miller process. The separation is achieved by passing chlorine gas into a molten alloy.
