Heat Resistant Clear Material Needed...

James,

I'm a bit late for you maybe, but when we lived in rural France, we had a log burning fire with glass windows in the doors. One broke and I went to the local fire dealers. He directed me to a glazier/ glass supplier who cut up some high temperature glass to size for me, specifically for this application. I dare say similar is available in the UK and they should be able to cut it into circles and drill holes in it, too. That way you only pay for the finished article.

There is an interesting article about mica on the British Mica Company website, it will stand up to 900c, and the largest piece found was 330 tons!

Many years ago, as a country ironmonger we used to sell sheet mica for oil heaters and slow combustion stoves, the memory is fading, but I'm pretty sure we used to cut it with normal scissors. Happy days!

Somewhere in the house I have a small book, just post ww2 by George Wakefield on how to make a photographic enlarger.

It asks for a 2.25x3.25 piece of flashed opal glass and a similar sized piece of heat absorbing glass - but if you were concerned it might shatter you could ask for that to be supplied cut into a series of strips, obtainable direct from Chance Brothers Glass, Oldbury.

In more normal times I drive home down the M5 past the remains of the Chance works I wonder at a company supplying such a small order from the factory!
