Glass Forge is a Refinement Building that refines Sand into Molten Glass. Created Molten Glass is released through its Liquid Output with a temperature of 1941.85 °C / 3527.33 °F, and should be cooled by other means. Recipes take a base time of 40s to complete and benefit from high Machinery.

Glass Forge is a unique building in that it can be used to reheat cooling magma.

Tips

• Molten Glass has a freezing point of 1126 °C / 2058.8 °F and will solidify into Glass almost instantly when exposed to normal temperatures. If this happens inside a liquid pipe, it will cause "cold damage" and break the pipe. To avoid this, use Insulated Liquid Pipe for the Glass Forge output and make the pipe as short as possible.
• It is usually sufficient to drop the Molten Glass out of a liquid vent onto the ground. Although the temperature is very high, the amount of heat is not. The high temperature delta will cause the heat to dissipate quickly but the low mass and low Specific Heat Capacity mean that the total effect is comparable to other industrial machines. Some care should be taken - it's probably a bad idea to have Lead (melting point 327.5 °C / 621.5 °F) on the same tile as the cooling Glass - but generally the heat can be treated like any other source.
  • To put some numbers on the heat output, if the Glass cools down to 100 °C / 212 °F and the Glass Forge does a job every 40 seconds, the heat from the glass would be around 650 kDTU/s. This is quite a lot of heat. However Glass is typically not in high demand so the Glass Forge may have an uptime of only around 5%, making the heat far more manageable.
  • Glass Forge can be power-positive when the output is dropped into a steam chamber with one or more Steam Turbines. This requires the Machinery attribute of the operating duplicant to be at least 10 to minimize operational time and thus energy consumption. To transfer heat efficiently, the solidified glass can be cycled through Conveyor Rail in Metal Tiles in the steam chamber.
• Dropping the molten glass into water is an effective way to freeze it.
