I know that this concern has been discussed here many times but now it is MY concern: granite vs marble. I love the look of marble but having once had two unsealed white marble bathrooms I swore, never again. I am wondering now whether with a good sealant marble countertops would survive a) blueberries b) tomatoey spaghetti sauce and c) the yellow stuff in the middle of lilies. As for granite, one is reasonably careful but inevitably something will get dragged across a countertop, probably either Cuisinart or toaster. Will it not scratch? After 20 years of Corian I am tempted to go with stone for its beauty but I want practicality too. Comments invited.
