This stone has some element of free iron in it which can oxidize or rust over time when exposed to heat or moisture. This is inherent in the material. If this is a concern, choose a different material. See Applications Guide for alternatives. Due to the incredibly High Abrasion Resistance of this material, it can be difficult to quarry and fabricate. This affects availability, fabrication lead times and cost. This material has a high absorption rating and will stain when exposed to oil and highly-pigmented liquids (i.e. wine). This material typically has naturally-occurring cracks and fissures. Expect to see factory repaired (resin, etc.) cracks and fissures.
