Molten glass detail

Molten glass is used in the Crafting and Construction skills. Fritz the Glassblower on Entrana will teach you how to make molten glass, but you do not need to speak with him in order to make it. Molten glass can be created through the Crafting skill by using a bucket of sand with soda ash on a furnace, granting 20 Crafting experience. Strange rocks for Crafting may occasionally be found while making molten glass.

Alternatively, you can use the Lunar spell Superglass Make, which converts all buckets of sand and all seaweed or soda ash into 30% more molten glass. This method only gives 10 Crafting experience but also gives 78 Magic experience.

Turning molten glass into untradeable empty light orbs, then disassembling them is a good source of Clear parts and several other Invention materials.

Gathering materialsEdit

There are many ways to gather the raw materials but one of the fastest ways is to talk to Bert in Yanille; he will ship 84 buckets of sand per day to your bank if you talk to him after completing The Hand in the Sand. Also, 80 noted seaweed per day can be bought from Arhein in Catherby for 2 coins each. Note that Arhein does not stock the seaweed in his shop; players must choose to talk to Arhein and use the prompt: "Can I buy some seaweed?" There is also a bank and a stove right next to Arhein for turning the seaweed into soda ash.

Fritz the Glassblower will buy molten glass for 20 coins (25 with the ring of charos) which is more than the price offered by general stores (1 coin), but less than the Grand Exchange at 166 coins.

Completing Desert Tasks rewards Desert amulets, which can be operated to quickly convert soda ash to molten glass daily: amulet-2 gives 50, amulet-3 gives 100, amulet-4 gives 150. You must be standing in the desert to do so, and amulet-2 and above provide free teleports to Nardah.

In order to make many of the items, you must use a glassblowing pipe.

TriviaEdit

  • In real life, the main component of glass is silicon oxide, which is what primarily makes up sand. Soda ash (sodium carbonate), historically obtained from burning seaweed or kelp, is added to reduce its melting point and make it easier to work with.
