What compound that changes color with temperature?
« on: July 12, 2004, 07:44:06 PM »
What compound or type of compound is green (clear) at room temperature but changes to a orange brown (still clear) when heated and is almost entirely orange (and clear) at ~ 100C?

I know ZnI2 is yellow when hot, colourless when cool
