Molten glass is used in the Crafting and Construction skills, as well as some quests, to form glass items. It is created through the Crafting skill by using a bucket of sand and soda ash on a furnace, granting 20 Crafting experience. This only requires level 1 Crafting. Alternatively, players can use the Lunar spell Superglass Make, which combines all buckets of sand and all seaweed or soda ash in the player's inventory into molten glass, granting 10 Crafting experience per pair of items.
Molten glass is used in some quests such as Observatory Quest, Horror from the Deep, Wanted!, Desert Treasure, Another Slice of H.A.M. and The Fremennik Exiles.
Molten glass can be made into glass items using the Crafting skill by using a glassblowing pipe on them. Each item requires one piece of molten glass to create.

- All the ingredients for making molten glass (seaweed and sand) can be found on the island of Entrana, except buckets, but there is a Tool leprechaun found near the Hops patch on Entrana from whom you can withdraw buckets if you have them. There is a sandpit, seaweed spawns, a range for cooking seaweed into soda ash and a furnace to make the molten glass. There is even a glassblowing pipe spawn in a nearby house.
