How do you heat a brick to 800 degrees and measure the temperature across it

[jake-the-peg]

I take it that you can work out a way to measure the temperature on the "cold" side of the brick and a way to heat the "hot" side of the brick.

This means that your question come down to how to measure temperatures in the region of 800 degrees.

Do a search for Optical Pyrometer on your favourite search engine that should get you going in the right direction.

Best of luck

If you heat a brick to 800�C its temperature will be 800�C. see, no need for measuring.
if, on the other hand you are interested in heat conductivity at that temperature, taking a long brick, heating one end to 800�C (there are thermocouples in that temperature range and heating could be done with a big gas burner or multiple small ones for homogeneity) and then measuring the temperature profile of the isolated (insulated?) rest with embedded thermocouples might do the trick.

Use a thermocouple - one end on the cooler side, and one end on the hot

A thermocouple is two wires made of different metals, eg one copper and one iron joined at each end. If there is a temperature difference between the ends, a current flows. the size of the current is dependant on the temperature difference
