How to create Divine Crystalline Glaze
Divine Crystalline Glaze is an ingredient used in many different Pottery recipes, mostly for creating Golden Idols and regular Idols but it has other uses too. In order to create this item you'll need to collect Permafrost Crystals which drop from many of the different goblin enemies inside of Permafrost Caverns and Iron Oxide which you can gather from the elementals in The Hole (until it is revamped in Underfoot) and from many different elemental enemies throughout the game.
Once you have all of the required ingredients combine them together in a Glaze Mortar container. This container is usually purchased from Pottery Supplies vendors.
Combine these two items together in a Mixing Bowl to make White Lead. Both items are sold by Eyasie Dyrius and Quareran Borius in East Freeport.
Iron Oxide Steamfont Mountains Farming
This location is personally my favorite for farming Iron Oxide because while farming for it you'll also be able to kill the Brownie enemies that wander around in this area and collect Brownie Parts too which are used in a subcombine to make Misty Thicket Picnics.
