Glass: Manufactured material, though can occur naturally
Pros/cons:
Stain resistant
Hygienic because not porous
Durable if over 1: thick
Expensive
Can chip and crack
Cannot be repaired
Not heat resistant
Resistant to scratches
Shows fingerprints easily
Maintenance free
Can do only glass (thicker piece), or lay glass on top of another surface (thinner piece). Both will have a green/blue colored edge due to the iron in the glass
Large shards create a bold look and finely ground glass is a more subtle look
How to clean and maintain glass countertops:
Use soft cloth or sponge
Use a commercial glass or multi-purpose cleaning product
For a natural cleaner, mix distilled water and vinegar
For stains and spills, use dishsoap, water and a soft cloth
Never use paper towels as it will leave a lint residue; a microfiber cloth is much better
