Pachyderm Ltd Run is described as "an opaque grey laden with silver"
Testers reported "As a rod, this glass looks like a medium grey. When melted it lightens and warms up into a sort of fawn grey - not completely brown and not completely grey . . . Pachyderm does tend to strike softly as you work it, warming up a little more the longer it's worked. They grey spots seem to disappear after a short while, leaving it a light tan"
