In Experiment One, I just decided to test the technology's viability.

To do this, I mixed barium titanate in an alkyd yacht varnish in a 1: 1 ratio and applied it with an airbrush in a thin layer on a PCB strip. Then I applied a layer of a mixture of blue phosphor EL-455, again in alkyd yacht varnish in a ratio of 2: 1, and then glued conductive glass on top with a drop of alkyd varnish. This sample No. 1 worked, although, after a week of lying on the shelf, it darkened noticeably and almost completely lost its brightness. In attempts to squeeze at least something out of him, he burned out and will never shine again.
