What would be the best metal to use for a blech — one that conducts the heat and withstands the high temperatures without being damaged?

April 10, 2019 12:17 pm at 12:17 pm #1712795JosephParticipantAre you making your own blech?
April 10, 2019 12:25 pm at 12:25 pm #1712800Gerufa u’tmuna can be accomplished by any covering of the fire and he’ker – in past tin was used because it was cheap and easy to use, but any material (for safety – fireproof and heat conducting) can be used.
BTW – A layer of aluminium foil would not be “kosher” for a blech because it would be bottel to the oven (unless several layers are used).

Based on thermal conductivity, melting point, and cost, it seems to be the most reasonable option.

April 10, 2019 1:14 pm at 1:14 pm #1712923MenoParticipantI just read that Beryllium is very toxic, so I would ditch that idea.
April 10, 2019 2:17 pm at 2:17 pm #1712927ChadGadyaParticipantSolid gold would be the best conductor. At current prices a slab 60 by 60 cm and 2mm thick would only be about $30,250.
