Test to observe the radiant heating of a beaker.

Not the most efficient -- the hot plate is 500W and on high.

The element is just barely glowing a dull red but putting off significant invisible radiant infra red which is largely absorbed by the beaker glass, causing direct heating on the beaker itself.

Is is that one a flask? Whatever.
