Hi y'all!! I'm new to the forum, but have had a clay oven for about 6 years now and am thinking about making some changes to it. The positives are that it was real easy to make, with low cost (I paid a mason to make me the pedestal; otherwise all else was free from Mother Earth). The negatives are that clay is weather (and bug!) susceptible and needs to be protected. So, if anyone has any experience here (like any particular coatings that have worked as a weather barrier) I'd be interested in your experiences! Thanks!
