About This Tool

Often confused with gemstones or minerals, glass comes in natural forms (like obsidian or fulgurites) and man-made forms (like sea glass or slag). Our AI can identify characteristics like conchoidal fracture and air bubbles to determine if a piece is glass.

📸 Tips for Best Results

✓Look for tiny, perfectly round air bubbles (indicates man-made glass)
✓Capture the curved, shell-like fracture surfaces
✓Hold up to the light to show transparency
✓Note the texture (frosted for sea glass)

🧠 Interesting Facts

•Obsidian is a naturally occurring volcanic glass
•Fulgurites are glass tubes formed when lightning strikes sand
•Sea glass takes 20 to 40 years, and sometimes up to 100 years, to acquire its characteristic texture
•Glass is an amorphous solid, lacking a crystalline structure
