Slate is among the natural stones that can withstand high temperatures.
If slate is sufficiently heated and compressed it becomes phyllite.
No. Slate is harder. Slate is shale that has been heated and compressed.
phyllite
Gneiss.
Slate has a conchoidal fracture. This happens when a blow is strong enough to peel off a flake of the slate.

phyllite
The slate or slate changes into schist
Gneiss.

it melts
Slate is already a metamorpic rock. It is formed by the action of heat and pressure on shale. Further metamorphism may produce phyllite.
Slate is silt changed under pressure.
When matter is heated it will expand
When solids are heated they turn into liquid
The process is called Metamorphosis of Rocks. When the slate goes under the conditions of high pressure and heat it changes to schist or gneiss. Type of slate decide whether it gonna be schist or gneiss.
