Lanthanum metal 99.7% piece

from 4.75

The rare earth metals family is more formally known as the lanthanide series and that's because lanthanum kicks off that row of the table. Lanthanum is a relatively soft metal that when freshly cut looks has a medium gray luster similar to iron. However, if left out in the open its surface slowly oxidizes first turning dark then over time a puffy white that comes off at the touch. When stored in oil the oxidation still takes place and the luster is gone even faster but the reaction stops there and leaves the metal looking a blue-gray.

We'll send your in oil unless you prefer to have it sent unprotected in which case we'll pack it in a vacuum bag and it will reach you lustrous though, of course, you'll have to do something about it if you want it staying that way.
