what temp does glass melt
Glass doesn’t melt at one exact temperature, but most common glass melts somewhere between about 1400–1600 °C (2550–2900 °F), depending on the type and composition.
Quick Scoop: What temp does glass melt?
- Typical window/bottle (soda‑lime) glass: starts to truly melt and flow around 1400–1600 °C (2550–2900 °F).
- Industrial glass furnaces often run around 1500 °C to keep glass fully molten for production.
- Lead crystal (lead glass) can melt much lower, roughly 600–700 °C (1110–1290 °F), because lead oxide lowers the melting range.
- In practice, glass softens first, then becomes more like honey, and only at higher temperatures becomes a fully runny liquid, so makers talk about a melting range rather than a single point.
Think of it less like ice (sharp melting at 0 °C) and more like very stiff honey that gradually loosens as you keep cranking up the heat.
Mini note on “latest” context
Modern glassmaking and glass‑art tutorials in 2024–2026 still use similar furnace ranges: roughly 1200 °C for working and shaping, up to about 1500–1600 °C for full melting in industrial setups.
TL;DR: For most everyday glass, expect a melting range around 1400–1600 °C, while some special glasses (like lead glass) can melt hundreds of degrees lower.
