The rule I was taught was, with at least three teeth always in the thickness of the material, the cut will be smooth.

I use 24 - 32 tooth metal cutting blades.

The tricky part of this rule when cutting wood/glass composites, is the glass layer is sufficiently harder than the wood core that it is essentially being cut as a separate material. And it is only a few 1/1000ths of an inch thick so, it is nearly impossible to apply the 3-tooth rule to the glass layer.

It is hard to avoid the blade hooking the edge of the glass and pulling it away from the wood.

Part of the key to getting around this is to use sharp blades, with lots of teeth. The sharp blades cut easily and more teeth does reduce the individual impact of each tooth. I use the same blades as Etienne, partly because they have ground teeth, where some cheap blades have stamped teeth. The slicing shape of the blade seems to work very well. Replace old blades early.

One other option that I have been using recently is using a router to cut holes. The spinning bit doesn't put the same impact hits on the laminations.
