Heat resistent material for baking plate

Could you clarify exactly how you intend to use the bbq to cook the food on that plate.

Grilling means to have the food on a surface (plate), and the radiant heat comes from above.

Baking means to have the food on a surface (plate), with the heat being mainly convective air, heated from below that surface.

From your description, I am unable to determine whether you intend grilling or baking the food.

In my location, it is coming into the bbq season.

Thanks for the message. The food will be baked by convective air from below.

See if they have any tiles left over from the space shuttle!

I don't believe there are any easily obtainable, cheap materials that you can cook on that will allow you to touch them without being hot and still cook on, or in. There are many that will dissipate heat quickly, but they do not stay cool while actual cooking is being performed.

Thank you for the message. What materials will dissipate heat quickly.

There appears to be opposing requirements for your plate material.

Any material which may be used as bakeware, so that the heat is properly transmitted via convective hot air to the food on that plate, must have a high heat conductivity: Metal, borosilicate (Pyrex) glass, earthenware, or similar, or the heat will not be conducted properly to the under-surface of the food - thus overcooked on the top surface, while undercooked below.......(What exactly are you hoping to bake ?)

This high heat conductivity requirement means that the plate itself will become hot during the baking process, with the problem of the high heat conductivity of the plate material, thus burning the fingers/hands on removal from the oven.

So.........what you are needing is a plate material with an extremely low heat conductivity, zero absorption of food product, which remains "cool to the touch" while the food on the plate remains hot, is capable of being washed and sterilized between uses etc.

I do not presently know of any material which complies with those requirements, except wood or similar materials.

I came across a low thermal conductivity material which could be formed into plates, but may be absorbent, looks as if it is fibrous, and thus not easily sterilized between uses.

Insulating Board Material has low thermal conductivity.

October 23, 2002 - Model V-19 Block, 1900ºF vermiculite composition board has nominal density of 24 lb/ft³ and average compressive strength of 134 psi. With no organic binders or fillers, material's fibers do not cause discomfort during installation. Dimensions, cut to size, provide tolerances of ±1/16 in. (max). It is available in standard 36 x 12 in. size block with thickness increments of 1, 1½, 2, 3, and 4 in. Standard blocks can be made into various shapes.

If your cooking arrangement was altered, so you didn't use a bbq, then a microwave or diathermy type oven could be used - in which case borosilicate (Pyrex) glass could be used, as the food itself would be heated, at the same time the plate would remain cool to the touch.

But because we don't know what you intend cooking, it is somewhat difficult to help.

I'm still thinking about the requirements for your plate material.

A thin wire baking rack, as used in a roasting pan, covered with non-stick aluminum foil. Food will cook well on the bottom, rack will cool quickly, food should not stick and clean-up is a snap. Your basic KISS principal.

Hello Jaguar, General Electric Plastics - now under SABIC (Saudi Arabia) management has a material SUPEC, which is POLY-PHENYLENE SULFIDE (PPS). This is a high temperature material for non-stick applications in the type of situations you have come across. Though I am not able to give you a "design idea" at this point of time, for want of knowledge on exact situations in your set up, I feel this informations should help you, as it is a non-stick material with structural qualities far superior to TEFLON. GE has an excellent interactive site: http://www.geplastics.com/ but you may have to register in order to get data. Also, you may "contact" the technical personnel through the site, for more definite data and help.
