Hardness: This refers to how tough a stone is and how resistant it is to scratches and damage. Some stones, like granite, are as hard as a superhero's shield, while others, like limestone, are softer and more prone to scratches.
Density: This is how heavy a stone is compared to its size. Some stones, like marble, are as dense as a superhero, while others, like sandstone, are lighter and easier to carry.
Porosity: This is how easily water can seep into a stone. Some stones, like limestone, are as porous as a sponge and can absorb water quickly, while others, like granite, are more resistant to water and are as impenetrable as a superhero's armor.
Durability: This is how well a stone can hold up over time. Some stones, like quartzite, are as tough as a superhero and can last for centuries, while others, like sandstone, are less durable and can crumble like a cookie.
Appearance: This is how a stone looks, including its color, texture, and pattern. Some stones, like onyx, have a polished and shiny surface like a superhero's costume, while others, like slate, have a rough and natural appearance like a superhero's hideout.
Chemical resistance: This refers to how well a stone can resist damage from chemicals, like acids or alkalis. Some stones, like granite, are as resistant as a superhero to chemical damage, while others, like marble, can be easily damaged like a superhero's arch-nemesis.
Thermal conductivity: This is how well a stone conducts heat. Some stones, like basalt, are as good as a superhero at transferring heat quickly, while others, like sandstone, are slower and less likely to burn your fingers like a superhero's cool gadgets.
