Why do some colors turn transparent when heated?

Hey All,

Haven't actually ever posted on here before because that darn search function is so handy.

Couldn't find an answer to this random question however: Why do some colors go transparent when heated and then return to their "normal" opacity when cooler/cold.

I'm thinking of those colors you use that when you're say heating the lip, the lip goes clear, while the rest of the body of the piece remains normal, and then as it cools down, it returns back to the same opacity as the body. Is it simply a form of striking even though this process doesn't alter the color? After all, the final piece looks like the color bar in the end. Random Thursday thoughts.

Many thanks!
