What is Glass?
Glass is a Minecraft block classified under the default material group. It has a hardness of 0.3 and a blast resistance of 0.3. It stacks up to 64 per inventory slot. It is a transparent block, meaning it doesn't fully block light or vision. Glass does not emit light. Glass filters 0 levels of light passing through it, even though it is technically transparent.
Namespaced identifier: minecraft:glass. Command: /give @p minecraft:glass 1.
How to mine Glass
Glass can be broken with any tool, or even by hand.
Break times (unenchanted, no Haste or Mining Fatigue):
- With the correct tool: approximately 0.45 seconds
- By hand (no tool): approximately 1.5 seconds
Using an Efficiency-enchanted tool, Haste beacons, or a Diamond/Netherite tier drastically reduces these times. Water and being airborne slow mining by 5×.
Glass drops
When broken, Glass drops:
- Glass (Silk Touch required)
Silk Touch preserves the block itself; Fortune increases quantity of ore-style drops but has no effect on ordinary blocks.
