 Re: sparplast 30ar
Thanks, StonyLake! Good find!
The silica and other nonorgainic stuff should not be a problem much more than cement. You are supposed to wear respirator, safety glasses, gloves, etc. to avoid contact with the stuff and should take a shower after working with it.
The SPARPLAS 30AS sheet says it can have 0 to 5% amorphous polymer. That could be almost anything. The amorphous polymer we used to make at the polypropylene plant I worked in contained xylene, benzene, and toluene which are definitely to be avoided.
Couple of points. First the SPARPLAS may be clean - i.e not contain stuff like that. However, if it isn't those are pretty heavy molecules and won't just vaporize quickly to give you a clean oven. They have fairly high boiling points so they will probably release to the atmosphere over a prolonged period. (Note: they should cook out of the surface fairly quickly but it might take some time to get them "out of the interior of the refractory) And finally, I know I mentioned food grade for it is an interesting thing to consider, but I doubt regular fire bricks are technically "food grade".
Good luck!
Jay
