A while ago Eli went to the mattress with Atmoz over blankets. It was pointed out that there are styles in science and the bunny's is to do illustrative experiments. If they carry Darwin credit, so much the better. It's not for nothing that chemistry is called stinks and bangs and physics shocks and explosions. If we wanted to play safe we would have taken up financial futures. Which, come to think of it, is what the theoreticians did in case you have any questions about why the world is in an economic mess.
Eli will rewrite this for the G&T response, and there are some refinements that have to be made (for one thing we have to measure the temperature of the upper and lower surfaces of the glass) and it has to be done in vacuum, just as gravityloss pointed out, also take a look at the blanket wars posts) but he thought some would be interested.
The lab bunnies started with a heating plate, fed at ~40 VAC through a Variac. Eli placed a couple of thin glass tubes on this and a large glass plate about the some size as the heating plate on top of that. You have to look carefully to see the plate, but you can find the greenish tinged edge. This heated up to ~166 C at equilibrium. Couple of caveats. The temperature varied ~2 C over 5-10 minutes, the thermocouple used to measure temperature is the blue wire to the left, the plate is a 2" diffusion pump heater, the glass tubes Pasteur pippets and the glass plate a large cheap lens from lord knows where. You use what you got.
Eli then grabbed the glass plate with his hands (One of the skills you pick up after forty years in the lab is a certain ability to touch hottish things. Comes in handy in restaurants) and removed it. The temperature rapidly decreased to 151 C in a minute. BTW, Eli is insensitive, but he can't pick up anything much over 70 C without illegal asbestos glass blowers gloves.
