Physical Properties

Composition :
Muscovite,Cericite, chlorite,hematite, kaolinite, micas, quartz,clay and other accessory minerals (wide variation in composition).

Hardness :
Soft – easily scratched. They can also be as hard and dense as granite

Absorption :
Low – medium oil, water other liquids.

Tendencies :
Absorbs oils and liquids…Softer/medium varieties scratches easily.

Weathering characteristics :
Due to the wide ranges of slate, this stone has wide ranges of weathering. Cleft planes provides permeability for water penetration resulting in spalling and flaking. Slates that have a high kaolinite content (a clay) display accelerated rate of deterioration in wet environments

Colors :
Colors vary widely

Finish :
Different finishes such as acrylic, wax, natural cleft, honed etc.
