I think those quests should be changed in "Create gilding for [x]".
Two reasons for it:
1st, making an artifact just means getting the gilding and a pair of clogs, then throwing them on the ground.
2nd, it makes more sense to be forced to make the gilding yourself. Artifacts can be made by someone who doesn't know either the gilding and the clogs (or whatever u use). For all other crafting quests you need to craft yourself the stuff.
Also this would allow you to actually use those gildings, if you made them with decent stuff.
