Ironman verdict

5 monsters drop it. The easiest is Killerwatt (level 55, 14/128); the best rate is Dust devil (elite) (level 95), at 4/40, about 18 per kill. You can also make it yourself: it takes 1 Cooking and gives 1 Cooking XP, using Seaweed. There are 2 other recipes below. Other sources include Ithell worker. Making ten takes 10 × Seaweed and gives 10 Cooking XP. 2 recipes use Soda ash, including Blessed molten glass and Molten glass. Soda ash 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, which is 1 less than the shop price, so buying it to alch does not pay.
