Writer's Block: How Soon Is Now?

[Error: unknown template qotd]Working gene therapy.

Oven puddle fail.

A while back, I bought brown polymer clay, which was manglified by Mousie. I found a brown, manglified lump today, and attempted to use it.

It looked like polymer clay. Smelled like polymer clay. Squished and shaped and molded like polymer clay.

In the oven, it melted into a puddle of brown goo. WTF??

And why couldn't I have figured this out *before* I mixed some into some new green clay???
