[Bernhard Masterson]

Hello Dulane,

If the clay dung plaster aesthetic is agreeable to you I would recommend just leaving it.  I do not recommend oiling the plaster since oiling will dramatically reduce the oven's ability to "breathe".  Baking puts moisture into the mass of the oven.  Avoid any barriers or materials that will limit evaporation/drying.  

Happy baking!
