What are you making out of interest?Having difficulty keeping the heat in and even when
welding small modeling bits together
I could do with an asbestos blanket if anyone has one
yep pack broken soft grey thermolite bits of blocks round the job works a treatI use some old very light breeze blocks.
Do read Optima’d post above. Storage heater bricks are for storing heat, not giving much out until a lot of heat has been absorbed all the way through. I, too, advise strongly against using these as insulation.Use bricks from a night storage heater, construct an 'enclosure' to reflect heat back onto the workpiece.
Better than firebricks.
