People sometimes assume darker, busier marble is tougher. Emperador is still marble, which means:
- It reacts to acid. Wine, citrus and vinegar leave dull patches that stand out against the warm polish.
- Its veining is busy. That hides colour for a while, but not the dull sheen an etch leaves behind.
- It is porous. Oils can darken it in patches that are hard to draw back out.
