Slate countertops are not completely heat-proof. While slate is heat resistant to an extent and can handle hot pots and pans, extreme heat or prolonged exposure to high temperatures can still damage the surface by causing cracks or discoloration. It is always advisable to use trivets or hot pads to protect the surface from direct heat.

Yes, slate is harder than shale. Slate is a fine-grained, foliated metamorphic rock that has undergone more intense heat and pressure than shale, a fine-grained sedimentary rock. As a result, slate is more durable and resistant to erosion compared to shale.
High pressure can cause the formation of the metamorphic rock slate from the sedimentary rock shale.
The slate or slate changes into schist
When mudstone is subjected to heat and pressure, it undergoes metamorphism and transforms into a rock called slate. The minerals in the mudstone recrystallize, and the rock becomes more compact and exhibits foliation. With further metamorphic changes, slate can further evolve into phyllite and then schist.
when shale is subjected to heat and pressure, it can be metamorphosed into slate.

Slate starts as clay. Thhrough erosion and nature, the clay can change to shale or slate. Shale happens when layers upon layers are of clay and sediment are piled together and held in place with something very very heavy. Slate is altered shale that had low heat and not very much pressure put on it. It takes thousands of years for slate to change. Slate can be any color but is mostly found in gray or black. When it is broken, it splits into layers.

Slate and shale have the same make-up. Slate is formed from sedimentary shale by pressure and heat. Wet shale has the same smell that wet slate has.
No
No
subjected to heat and pressure. The intense heat and pressure cause the shale's minerals to recrystallize, giving rise to the fine-grained texture and foliation characteristic of slate.
If you apply shale with intense heat and pressure. you'll get slate. Now just apply intense heat and pressure to the slate an over time you'll get your schist
