Polymer (Gloss) Medium — A general purpose liquid for glazes, extending colors, enhancing glass, and increasing film integrity. It's oil-like and resinous, promoting flow and leveling.

Matte Medium — This is a general purpose, pourable medium, for extending color, decreasing gloss, and increasing film integrity. It can also be used to create a clear ground, instead of gesso.
