Anyone know what Deacons, Perthshire and other factories UV results are??For my six examples by Perhshire Paperweights:
longwave uv = three fairly bright green, two as a colour that in the past I have called "watery orange", but which other folk might see as "greenish-orange" or as "pinkish" or even as "no fluoresence" and one as "no fluoresence" but might actually be a "watery silver-grey" (this one is a Peter McDougall 1/1 type but very similar to a known design from the later years). I have exmained other peoples' PP weights and "silver-grey" does show under longwave for many later period items.
shortwave uv = all blue except for one which is the 1/1 type mentioned above.For my eight examples by John Deacons:
longwave uv = all but one are the "watery" (hard-to-describe) colour; the other (a blue overlay) is more of a "silvery grey" in the clear glass
shortwave uv = six are blue and two (both Stk items) are what I call "dusty grey".Antique French
I don't have any St Louis weights so I can't say what they might show as. But in the past I have put the lights on somebody else's collection of antique French weights and found that they mostly agreed with what was suggested back in the late 60s and mentioned (with cautionary comments) in Hollister, "The Encylopedia of Glass Paperweights
". "Peachy-pink" or just "Peach" was said to be the colour for St Louis under longwave uv.
