Flash point above 800 degrees celsius?

[ToastedToast]

Hey x)
   Does anybody know what fluid/oil has a flash point above 800 degrees celsius? I need it to heat up a house brick for my Physics practical exam plan.

Thankyou for your help x)

Hey toastedtoast, you do know that this PLAN is theoretical and you dont have to do it. I don't know what fluid has a flash point, I'm using a kiln, or you could use the furnace thing in the metal work room and blast the brick with the flame.

OK we've seen a lot of brick madness but using a fluid to heat a brick to 800 degrees is creative - insane - but creative.

If it's of interest (and it should be) I believe that the melting point of salt (ie pure sodium chloride - don't forget three are additives in the stuff you put on your chips) is only a fraction of a degree above 800 degrees C so if you were to very carefully heat a brick in a bed of salt you'd know when you were at the right temperature because the salt would melt.

No pyrometers no thermocouples but a lot of very hot very dangerous liquid salt.
