Soda ash is made into Molten glass to make glass items in Crafting. Soda ash is made using seaweed, giant seaweed, swamp weed, or edible seaweed on a range or fire. Smelting it with a bucket of sand in a furnace or the Lunar spell Superglass Make produces molten glass.
It can be purchased from Trader Stan's Trading Post at charter ships for 5 coins.
Uses - Comparing Molten Glass yield and XP[edit | edit source]
When using soda ash and buckets of sand in a furnace the molten glass yield is
1.0 molten glass per soda ash and bucket of sand.
When using Superglass Make with soda ash and buckets of sand the molten glass yield is
1.3 molten glass per soda ash and bucket of sand.
When used on a fire, giant seaweed turns into six soda ash upon successfully cooking, rather than just one given by normal seaweed. You can however fail, resulting in only one soda ash. Note that Cooking gauntlets do not decrease the cooking fail chance, however the Hosidius Kitchen cooking range effect still applies.
When used in conjunction with the Superglass Make spell, giant seaweed similarly acts as six regular seaweed and gives 60 Crafting experience per seaweed when cast. The combination of two giant seaweed and 12 buckets of sand yields on average 1.45 molten glass per bucket of sand, while the combination of three giant seaweed and 18 buckets of sand yields an average of 1.6 glass per sand, although with the latter some of the glass will fall on the floor as it overflows from the inventory. If it is not picked up, it results in an average of 1.488 glass per sand. If players obtain the sand via mining sandstone, it is slightly more efficient to not pick up the excess despite the lower return due to how quickly the materials can be obtained.
The average Crafting experience per giant seaweed varies:
- For an average of 1.45 glass per sand (two giant seaweed and 12 buckets of sand), each giant seaweed equals 538.5 experience when making lantern lenses or 669 experience when making empty light orbs;
- For an average of 1.488 glass per sand (three giant seaweed and 18 buckets of sand without picking up the excess), each giant seaweed equals 551 experience when making lantern lenses or 685 experience when making empty light orbs;
- For an average of 1.6 glass per sand (three giant seaweed and 18 buckets of sand and picking up the excess), each giant seaweed equals 588 experience when making lantern lenses or 732 experience when making empty light orbs.
These numbers include the experience from casting Superglass Make.
