Resapol

Resapol is a material from the Age of Infor. Though not magical in nature, it has some interesting properties making it highly useful.

First, it seems to exist nearly forever. Though it's not particularly robust and can break without too much effort, items made from it are still around and recognisable from this nearly forgotten Age. Tiny statues, small boxes with Resapol hinges and latches, transparent bottles, and straight white tubes can be found in nearly every corner of the world, particularly along shorelines and in the oceans. Most of these items have been scavenged over time for use with the second property.

Second, for someone with skill, it can be melted down and reformed. It can be coloured, or made transparent. It can be formed into nearly any shape. Though again not particularly strong, it can be made to be water tight and used in a number of practical or artistic purposes.

Third, for whatever reason, it cannot be duplicated by magic. Its use in the creation of unique items can be used to keep the item from being magically duplicated, for example.
