What is Slate made of?
Slate is a fine-grain, foliated metamorphic rock formed under extreme pressure and heat conditions from sedimentary rocks such as shale, clay or ash. What that means is that slate is made by literally crushing and melting other softer rocks together, which is called metamorphosis. When compacted, these softer rocks merge their qualities to create super-strong slate! The natural bands you see in our slate are called folation, the scientific term for when different kinds of rock are fused together. Since they are different from one another, they create layers like in a cake- but this cake is held together by molten lava! Below is a list of many of the textures you may see in our slate.
Please keep in mind these images are CLOSE UPS and that the actual markings in our slate cheese trays will be much more subtle and your surface will be generally smooth and uniform!
