My apartment has a small gas stove, and I'd like to build a small table next to it to act as additional counter-space (as there's currently no counter-space immediately next to the stove) and also as storage. As the stove is a gas stove, with actual flames (and it's completely non-electric, so the pilot lights are on at all times), I figure that I probably should use some sort of flame-safe material for the top of the table. Ideally, it would also be a material that'd be easy to clean, as the area around the stove tends to get greasy from splatters and greasy air (there's no hood or vent). Unfortunately, since it's a small table (the top will be ~18"x28"), I don't see a slab of stone being a very viable option. What's the recommended material for this sort of application?
