Today's expedition took me to Stone Technologies in Woburn for an educational seminar. I learned that acid (wine, lemon juice) reacts with the calcium carbonate in marble to etch the stone—those dull spots you may not want on your Italian treasure—while the presence of magnesium makes it harder and stain resistant. Igneous stone was once molten lava that cooled over time inside the earth to become granite. Natural hot springs caused the tiny holes in Travertine marble. Stalagmite and stalactites in caves are the sources of another decorative stone and if I could find my notes, I'd tell you what the name of that stone is.
Here are a few pictures from their slab supply:
This engineered terrazzo stone above is made from recycled beer and vodka bottles, while the one below has a much less varied palette and can be back-lit for dramatic effect.
You've all heard of butcher block, but until today I had never heard of Butcher Rock which has all the properties of granite with the fun addition of a bold graphic design statement.
