Liquid Glass Thinking Putty is almost imperceptible at rest. So much so, in fact, that many people believe the tin is empty at first! However, once you start playing with it, the putty begins to cloud.
Depending on how much you play with it, Liquid Glass Thinking Putty can either appear clear, like thick glass, like ice, or even unpolished calcite (crystal).
