Hot Cooking Surface Built Into a Wood Tray
Question
I found this product, Richlite, that I think will work, but it costs about $1000.00 for a 3/4” x 4’ x 8’ sheet. I haven’t given the owner a cost yet, as I’m just doing the research now. Any ideas to help me lower my material costs? Forum Responses
A few ideas: glass, silicone, cork, sacrificial piece of wood (like when you order fajitas), ceramic. Glass would probably be the best as it is an insulator and has a very high melting point.
From contributor T: Bamboo with two strips of aluminum or stainless steel to get an air gap. From contributor A: What were the old trays made from? If you are making a wood tray, why not just inlay some metal strips that stick up above the wood to set the rock on so that there is an air space between it and the wood? You could also inlay a ceramic floor tile into the wood. Look for a porcelain tile with a little texture to keep the stone from sliding around (floor tiles). I wonder what kind of liability issues this restaurant has when they are sending 450 degree rocks out to their customers. Do they have a children's plate?
From contributor P: I will be damned if I am going to go to a restaurant that I have to cook my own meal! From contributor G: Never had fondue? From contributor N: As mentioned above, there are insulating materials that are extremely thin, yet very effective. I remember seeing a guy hold a blowtorch to his hand with only a 1/8" piece of some of this stuff protecting it. Unfortunately, I don't remember the name of the stuff (it was not asbestos based), but you're certain to able to find a description and seller somewhere on the net. Glue the material on the bottom and sides and you're good to go. From contributor G: Contributor N caused a couple of my memory cells to kick in. Aerogel is that material. From contributor T: Nomex by DuPont. Also called Aramid. Same stuff the Ove Glove is made of. They use silicon as a non-slip grip on them. You could use a 106 high temperature silicone as non-slip grip on the Aramid fabric. Aramid is an insulator for temperatures up to 600 degrees F. Would you like to add information to this article?
