So I've got my oven mostly completed, just adding a few finishing touches (like adding some slip to the inside of the chimney and details on the sculpture) I'd like to not have to build a permanent structure over the top. Ive been looking at lime plaster; but one of the questions I have been wondering about is with a final layer of lime plaster(i have a bag of masons hydrated lime), from what I have been reading it needs to have a chance to cure with some residual moisture. How long will that process process take? Im in Northern California and its getting hot! I don't want to prolong my wait to fire up the oven any longer than necessary (i want some pizza, dammit!) Any tips or direction to resources would be much appreciated!
