Look what turned up yesterday evening.
Jet black solid colour perspex.
Just 4 7"x7"x0.5" samples, but with the option of a lot more larger sizes (12"x12") and colours.
They are used for studio mounting of professional photos, and any slight blemish they are rejected and thrown away.
What wonderful items for small machine display bases, laminating and machining of differing colours would bring all sorts of combinations.
Becasue they are such a deep black, they were a pig to get a decent pic.
