My dear departed mother was never much of a drinker but every Christmas morning the two of us would have some form of champagne cocktail. Often a Mimosa, which went down a treat. BUT the year we tried a champagne and strawberry liqueur mix was a disaster. Well not for mum and I, we giggled through until mid afternoon when crashed for a nap. When we woke we realised the peas went unserved, some people had the wrong presents and there was something very charred in the oven. The family still talks about the year we were too tipsy to cook lunch. This year it'll be straight champagne (and after 8 years I still miss her dreadfully).

Both have their place depending on taste and budget.

Got my answer - non combustible material such as, natural stone - marble, granite or concrete etc.

Thanks dreamer...yes I have made a mistake in my title!  Meant to be engineered stone vs natural stone. And thanks for all comments. Was hoping someone who actually had experience with natural stone in these areas and had a negative experience would comment.
