Composite kitchen sinks - Granite and Quartz?

Composite kitchen sinks - Granite and Quartz?

Answer:

Well, if it's quartz then its very hard and can scratch glass/metal. If it's glass then it wont scratch steel. You can smash it together with glass and see which one breaks first.. =] kevin S ---> Quartz comes in lots of different colors theres purple quartz and white quartz and this weird brownish quartz too i think

quartz is pure white so if its colored, chances are its not quartz
