Without a door I can't bake real bread, and do other fun stuff.
I spent a chunk of time today researching oven doors--particularly a door that could be made of fire resistant glass. There are two transparent ceramic materials that can be used NeoCeram and PyroCeram. They are rated to sustain constant temperatures 1290 and 1400+ degrees Fahrenheit, receptively. They are also quite expensive; a door my size would cost about $200, or more, just for the glass alone plus cutting and drilling charges. Here's a link to a glass door design posted on the Forno Bravo forum
The glass door would look great and let me monitor the fire from inside the kitchen and...it's just too expensive. So...
Option 2: oak. I would need 10 linear feet of 4/4 oak by 6" wide to fabricate the main door panel, plus a foot or two more for a handle & brace. If I do the oak door, I would back it with sheet metal and a layer of insulation. That's about $40 of oak, plus a couple dollars for the sheet metal and the installation is "in-stock" in my shed.
