Why can’t I use marble on my kitchen countertop?

There is no rule that you can’t. However, marble and limestone are more easily scratched than granite. The calcium carbonate structure of marble, limestone, and travertine is highly vulnerable to most household acids such as vinegar, mustard, ketchup, citrus and a host of other food related products. These acidic substances cause a chemical reaction that often damages the polished finish. However, consumers often find marble used in the kitchen as pastry slabs. It’s perfectly smooth, cool surface is ideal for rolling out dough and pie crusts.
