Hello "pyro-friends"  I haven't found a dedicated thread to this, and thought it could be useful. |

So, to "start the fire"...
Interesting properties(please correct me...): TRANSLUCENT. rated to about 750 C. Close to cero expansion with temperature rise. tolerates quick temperature changes. Can be cut like regular glass.
I can buy schott Robax brand 4mm thick. I am thinking of using a piece of 35 x 55cm as a cooktop (spanning maybe 30 x 50cm).
Anyone here with experience and or knowledge on this? Is the glass strong enough to withstand the weight and abrasion of cookware over time?
Cheers

Thanks Mathew. I appreciate your answer because I know it is based on experience. Have seen many of your stoves, very inspiring.
Have you had any special problems or concerns with Vitroceramic as cooktop? Do you think it extracts less, the same or more heat than an equally sized piece of metal?
Cheers

Thank you for the kind words ManU. The only concern with the glass I've experienced and can caution against is capturing it too tightly in masonry or metal. There needs to be expansion joints all around.
It's hard to say regarding the metal comparison. I find the glass radiates a surprising amount of heat into the space. I would say comparable to most metal radiators I've used.

Cheers You can look for different varieties of borosilicate glass. There are a lot of trademarks, like Tydex, Zerodur etc. Some of this materials able to withstand up to 1000C. I've been working with some materials known in Russia as sitall (ситалл). Long story short - you are looking for borosilica or alumosilica glass or ceramic. There are a lot of manufacturers. Quartz glass also might be an option. |
