Topic: Blue Uranium Glass Butter Dish?

[flying free]

I hope we'renot talking at cross purposes the fuzzy tint is only there when under the blacklight.  In the light of day they're all clear glass with no tint or even hint of a tint, even the older pieces.

This Victorian half-pint glass is a good example of manganese fluorescence, it shows best with the light shone across the thick base, the photo actually enhances the colour.

...and presumably the half-pint glass with manganese doesn’t register on your Geiger Counter in the way your blue butter dish does?

Ekimp, I wouldn't have considered testing it, but actually nothing whatsoever.

Thanks, that’s reassuring regarding your blue bowl containing uranium I would think

Ekimp, the intensity of my dish's glow convinces me, I'm still trying to find a maker but if it is American they often used uranium to intensify the colour of glass and there are examples online. I've still not been able to reproduce the true blue colour in photos, it's actually a dark turquoise/teal blue.
