Jura Grey is quarried from a boulder quarry in Germany. It is an extremly dense limestone which makes it a popular & smart choice for outdoor applications.
Limestone is a sedimentary rock mainly composed of calcium carbonate.
Like most other sedimentary rocks, limestones are composed of grains,
however, around 80-90% of limestone grains are skeletal fragments of
marine organisms such as coral, sea snails and other sea creatures.
These marine organisms lived in the sea billions of years ago. When they
died they fell to the bottom of the sea and rotted, but their shells,
which were made of calcium like your teeth, did not rot and just stayed
there. Pressure from other shells, from the water, and from sand being
washed over the shells, squashed them all together into rock. Billions
of years later, now that there is no longer a sea in that area, we have
found the limestone & quarry it.
Jura Grey is a very interesting color of limestone. It ranges quite a bit from a creamy grey to grey to blue tones to brown tones depending on the slab. It tends to have a few fossils, which are always fun to find in a limestone! It also has some white quartz veining in it.
Due to how much this stone can change from bundle to bundle be sure to select your exact slabs. When selecting tile ask to see at least a few pieces of the current stock so that you can see the color range you will get.
Keep in mind that since limestone is a calcium based stone that anything acidic WILL etch the surface....just like marble. Limestone may not be the best choice of material for your kitchen.
Other names for Jura Grey include: Jura Graublau, Jura Blue, Jura Gray and Jura Grau.
Jura Grey is available in 2 cm & 3 cm slabs as well as a variety of sizes in tile depending on the distributer. You will generally see Jura Grey with a
honed (matte) finish.
Thanks for the info. I seriously loved learning more about limestone. Your blog is amazing, I spent all afternoon reading the older posts and I have learned so much! I wish I lived in Utah, I'd love to see your showroom.
ReplyDeleteThanks again. Keep up the good work.
I've never seen Jura Gray limestone before. It's really pretty.
ReplyDeleteI am surprised to see that how beautifully the jura grey color of limestone has adapted with the interiors. I have rarely seen this color of tiles. But they are lovely...!
