The floating world
I remember when glass fishing floats were regarded as just so much rubbish. Now it seems they are popular and fetching high prices. I am not surprised. They have the unexpected beauty that comes from rough utilitarian objects cobbled together from bits and pieces. I understand they were quickly and cheaply made from old cast-off bottles and such. That is why they have splotchy inclusions and uneven walls. They only had to float; their makers did not pay any heed to what they looked like.
By contrast fishing lures are usually carefully designed to trick fish. But some fish are less fussy than others. I am told you can catch barracouta using the silver paper out of a cigarette packet on your hook.
A still life of glass fishing floats from Japan and a fishing lure found on the footpath.

It can be any colour, as long as it floats.
