But the real surprise happened when I lit the first one in the dark workshop! The whole shape lit up like a magic wand! It took me totally by surprise!
Here was this lovely flame floating in clear lamp oil in a vessel coloured with colloidal silver chloride (for a long time my basic ground colour), and the whole thing was glowing!
Not long afterwards I was visited by a lovely lady named Loretta, and I showed her this marvellous device.
