Scholars,
I was having a discussion with a fellow scholar this week on how, what tool/instrument measures some of the hottest things in the world, like Lava for example. This week do some research and find an article or website that would lead me to my answer.

Taking the temperature of lava is not as simple as sticking a thermometer into a flow. Thermocouples
and radiometric instruments can be used, as well as an indirect method that involves taking a sample
of hot lava, then quenching it rapidly in cool water. The cooled lava is taken to a lab and analyzed for
magnesium oxide (MgO) content. The formula for determining the temperature of the lava is
Temperature in Centigrade = (23 x MgO) + 1012. The greater the concentration of magnesium oxide,
the hotter the lava was.

We measure the temperature of lava by putting a probe of metal into it. Our thermocouple tells us the temperature, in degrees Celsius. the website is http://www2.scholastic.com/browse/article.jsp?id=4887
