El Horno de Union day 3, Seattle Cob Oven

Structurally the oven is all done now. We need to let it cure for a couple more days and then we'll take out the door (praying that it doesn't collapse), and remove the sand form from inside. After that we will still only light small fires, curing it slowly for a couple more weeks. On Monday I used the grill area on the side; it worked but the fire didn't stay very hot so I may need to add a grate that the coals sit on for better air flow. The lines all over it are to enable the final decorative layer to stick. We'll do that layer out of terracotta colored clay and press beach glass into it. The chimney is made of an old Seattle clay sewer pipe that I got from my neighbor; it's not for the oven, it was intended to encourage good airflow across the grilling area but at this point it seems to be more for looks than anything.
