Some common Marble King Patch mibs glow and some do not

[The Nickel Guy]

I have a bunch of Marble King 5/8 in players and none glow under UV. They are mostly white base Patch and Ribbon. I don't know why, but some of my shooters do. Now this one may not be a Patch and Ribbon of course but I am pretty sure it is a Marble King Patch.

I have others that look just like it and do glow and others that do not. Without the UV light, it would be hard to tell.

Just an observation.

I love a good UV glow.
I tried for years to finish a row of ten in a 100-count box of Akro "Prizenames", they were just basic yellow and--not quite white. (these are quite hard to find actually)
You will be amazed at all the different glass that Akro used and included in these simple-looking marbles. 
UV light spoke to me then and helped to get a good row that is consistent. It took some time but this is collecting-nuff said.
Backlighting and UV light are valuable tools to include in your arsenal—also a good bright pen light light and someway to see closer—I use magnified spectacles—just because.

 

These bigger ones never act like the smaller ones and visa versa--the tiny ones have a mind of their own as well.
Marble—On!!

I noticed that too with my MK’s but with 5/8” not shooters. Some glow some don’t. Is it the timeframe these were manufactured?

That's funny it is the other way around for you Meep. I'll have to dig em out and post a group picture when my batteries are re-charged. Both in the camera and in me as well. It's late but it's nap time.

I’ll try to post mine too. Good night where ever you are.

I lit up a bucket of marbles and found Bumblebees and MK Cats Eyes that glowed. Pretty cool. I think your OP is a Foreign Mushroom 🔥

I can see that. The white part. I remember there was a thread about that ot too long ago.

I just read that some marble companies use recycled glass so is it possible that MK used glass that had uranium in it and that's why we see it in some of the marbles regardless of the size and the date of manufacture? I also have a few fluorescent cat's eyes that are MK.

Almost all the marble companies used glass cullet that they purchased from a variety of glass manufacturers including some that used this type.
There is no doubt some marbles have glass from a maker that used this type including the window makers, the jar makers and the ponds cold cream makers-along with the many others.
Marble—On!!

Here are MK’s that glow and not glow.
