High-temperature wax, filling the void between inner and outer glass shells of this minimalist design boiler (along with a clear slightly-lighter liquid), absorbs and reflects incident light from the heating-element/burner.

As the kettle heats up the wax melts, rising and falling in liquid blobs as its density varies.

I suggest moving both this and the linked idea to the category product:kettle.

your suggestion accepted and acted upon after much consideration and a bit of hand-wringing, at an opportune moment of inspiration. thanks.

[xandram] I deleted your linked image because it was of the LED-lit kettle featured in my second link (which article contains the same picture).

Note that while very cool indeed, that one will only be interesting when the water is actually boiling, ie: when you should be unplugging it and making a pot.

The Lava Kettle does that too, albeit in black-body radiation red and behind the main show (which starts as soon as the kettle gets warm), if you let it continue to boil when the water's ready to be poured.

Doh!
My Lava Java idea has left the building...
