Ironman verdict

At least 9 monsters drop it. The easiest is Cockroach drone (level 4, 1/43,690.67); the best rate is Seren spirit, at 1/16, about 3.1 per kill. You can also make it yourself: it takes 1 Crafting and gives 20 Crafting XP, using Bucket of sand and Soda ash. There are 2 other recipes below. Other sources include Ice troll grunt, Ice troll female, Bork and Bandit (Wilderness), plus 4 more listed below. Making ten takes 10 × Bucket of sand and 10 × Soda ash and gives 200 Crafting XP. 35 recipes use Molten glass, including Bandos throne room sphere, Beer glass and Bomb vial. Molten glass is members-only. It is tradeable on normal accounts, but an Ironman cannot use the Grand Exchange or trade for it, so the sources on this page are the whole list. High Alchemy turns one into 1 coins.
