I've seen deep purple irradiated bottles for sale on Ebay with no disclaimer stating that they have been modified, which is against the site policy. I don't like bottles that have been artificially colored this way. It's ruining the historical value of an item. So I agree with what willong said.

ASC is a term they use. Amethyst Sun Colored.

but not near our civilized G-type star, even on the planet Mercury
I don't know about that since Mercury receives nearly seven times the solar irradiance that Earth does and has only 1% the magnetosphere strength at surface. Since it is also a factor in the colorization, how long duration of exposure are you willing to consider? I suspect that an exposure of just a few MERCURIAL DAYS at its equator might produce a noticeable lavender hue.

This is why I love this site. I can’t imagine having resources like this during most of my bottle collecting days. Just ask and someone out there can help.

Here’s my contribution. A 1/2 pint uServo milk. I did not apply any contrast to see the embossing, just white light to show color with no editing. I don’t collect milk bottles so don’t know much about this one other than age range. I keep it to demonstrate selenium colorization when i give the occasional talk.

Nice example. Hard color to call, to me it looks light rose beige.

I have a few 1920s small milks that have a light rose/beige tint. I thought the magnesium usage was stopped well before that.
By far the best SCA bottle I have dug is a little Albion Maryland whiskey bottle circa 1900-1910 I believe.

Recycled glass with manganese can be found in later bottles. This 1952 Coca-Cola hobbleskirt glows a nice green. From Newark, N.J.
