If, like me, you had no idea what melamine is or why it was such a bad thing to find in Chinese milk, I suggest this Tech.view column (for that, and a whole lot more):

Melamine is used to make durable work-surfaces for kitchen cabinets and bathroom furniture, and is formed into heat-resistant jugs, bowls, dinnerware, and other household items. To be accurate, such products are made not from melamine, but from melamine resin—a thermosetting plastic produced by combining melamine with formaldehyde.

… Melamine itself is a different matter. In low doses, it is non-toxic; its so-called LD50 (median lethal dose) is on a par with table salt. But should it be combined with a closely related chemical called cyanuric acid, the resulting compound (melamine cyanurate) can cause fatal kidney disease. Melamine cyanurate is widely used as a fire retardant.
