I'd guess the high heat used to fire ceramics would simply cause the

Yes they did the same with transmitters, often all you need was a
metal mop bucket and a piece of copper pipe

A water load bank is good for hundreds of KW at 60hz.

For use with a pair of 6146's we used to wire a lamp to a coax
connector. We had a load as well as visual indication of the relative
power output.- Hide quoted text -

I built a wattmeter of sorts around a circuit like that. After tuning
up the transmitter to light bulb dummy load I would measure the
resistnace of a photo resistor exposed to the light then see how much
60Hz AC voltage and current took to light the lamps to the same
brillance.
