Though liquid in nature, don't push me too far for then I will break, and the damage may scar. What am I?

Why this works

This riddle plays on the dual nature of glass, which can be both a solid and a liquid in certain contexts. The phrase "liquid in nature" refers to how glass is often described as an amorphous solid, meaning it has properties of both solids and liquids. The warning against pushing it "too far" relates to how glass can shatter or break under stress, leaving behind sharp edges that can cause injury, hence the “damage may scar.” The clever use of language highlights the fragile balance between glass's liquid-like qualities and its solid state, making it a fitting answer.
