The kiosk looks awesome. It gives me some ideas about a cool backyard project. I have always wanted an outdoor kitchen for when it gets hot during the summer. I have somewhat thought about an outdoor hearth oven, but keep thinking that a wood fired oven, while pretty darn cool, would probably be more effort than I would end up going through very often. Also, a hearth oven may or may not be attractive to a potential buyer if I ever want to sell my house. This, on the other hand, could very easily be a tool shed, child's playhouse, or whatever if I move (and of course I would take the oven with me).
I was wondering about moisture and the fibrament stones. Their FAQ's say:
Since baking stones are porous they absorb moisture. Moisture turns to steam at 212°F. If the moisture is forced out of the stone too quickly it can develop cracks. This is why a slow, gradual temperature increase is so important.
Even if we predried the stone at the factory it would pick up moisture during shipment to you. To ensure there was a nominal amount of moisture in the stone the predrying process would have to be repeated.
I sent Fibrament an email asking about outdoor storage of their stones and here is the reply I received:
If you store the baking stone outdoors it must be covered to protect it from the weather. If its stored outside for prolonged periods its best to bring the baking stone up to temperature slowly.
What are everyone's experiences with this? Do you leave it outside when not in use? Do you use a cover of some sort? Do you heat it up slowly? Have you had any problems with chipped or broken stones?
Also Willard, have you ever thought of selling plans only (or some type of fee based consultation service)? I have metalworking skills and a metal shop and would love to build one myself. I don't think your prices for finished units are out of line, or that any major improvements are necessary, but I would like to be able to say "I made that".
And for the sketches of the kiosk, did you use Sketch Up 100%, or did you draw them in a CAD program and then import them into Sketch Up? They look really nice.
