Ok, thanks. I suppose the ones with red in, where it's pretty tricky to spot could just be colour reflecting making me think it's fiery. I'll post some better pictures of the ones where it's most evident

Ok, so I think these are a mix of vitro and MK. I've been through them repeatedly, along with a load of similar looking types, back-lighting them.
I've sorted these as showing varying degrees of "fire" inside.
Some it's easy to spot due to the structure, however on others, it's more difficult, just seeing a glimpse through the seams, however it definitely seems to be there, especially when I'm comparing with others that don't have it.
I'm aware of vitro opals but didn't realise MK had produced marbles that had this, although perhaps it's from the peltier cross over period (if I've got my time line straight).
I know it's a pain, due to numbers, but if anyone is able to give me clearer IDs on these, I would be really grateful.

Its a type of higher power UV light. Lately, more people are buying cheap, high power UV lights while ignoring the eye safety issues that come with their use. Looking at 395 and 365 without safety glasses over time leads to cataracts or macular degeneration. Most people seem to ignore this FWIW.
Thanks for this information, I knew as far as to not shine it directly in my eyes but this is definitely something I will take note of.

Aha - thanks for the hint, I'll start looking at MK Rainbows

Thanks for your response. Uv 395 is the wavelength of uv light that I used. Yes, I think I'm swaying towards vitro too actually, as I have spotted very similar shades and patterns on some others...

Opalescent?

Very difficult to capture in some cases, I've messed with light levels a bit on some to try and show it but it's not always as evident in these pictures as it shows up in real life.
