Regarding how to identify plastics, there is an international code.
Often you´ll find a small triangle etched on the base of plastic containers,
and in the triangle there should be a number (ranging from 1 to 6 or 7).
Please excuse me for some spanish terms, but my english and chemistry

Hi Todd and all
I guess HDPE = High-Density PolyEthylene.
Is there a simple way of identifying plastics, and other than HDPE,
which types would be suitable? I've had

American Plastics Council has a pretty good description of the

I understand that glass or stainless steel are best for preparing
methoxide, but what about
plastics? Which plastics work, which do not, and how do you tell ? other
than sacrificing a small
sample in a glass jar of methoxide).
