Does a slide made from color reversal film take damage when used for several hours in a slide projector?

So I'm planning on projecting slides made from color reversal film for a long continuous amount of time in an old fashioned slide projector and was wondering how much damage the heat from the projector lamp might cause the slide.

I already figured it would probably be a good idea to make a copy of the slide and use that so the original doesn't get destroyed. But in theory what are the risks if say I kept the slide in the projector and the projector turned on for a whole day?
