The white mese lamp finally has a recipe and should now appear in the craft guide. The white mese lamp was added very quickly as to not break the import of Arisha_L's Sky City. The addition of the recipe was overlooked.

The recipe is:

blank, Mese Crystal, blank
Mese Crystal, Obsidian Glass, Mese Crystal

As I believe maikerumine to be the creator of the White Mese Lamp, I am using his recipe creation as well.
