OK - I changed the battery on the caliper! It says .60-.70 inches. Sorry about the bad measurements before. I cannot positively ID a clay marble b/c, although I have seen them, I have not, that I remember, hefted a legitimately identified clay marble. I only said the terms "pottery/porcelain" b/c it reminds me of the same feel/look/matrix of the porcelain insulators I research/collect. I will gladly defer to your knowledge on this being a mill ball. When I inspect it under high magnification, I see where the blue coloring seems to fade outwards onto the white from the blue areas. I am only familiar with porcelain glazes like pottery and insulators, and do not know how to determine an authentic painted clay (again - assuming this was done!) marble. Is there some place I could read more about the mill balls and also clay marbles in general? Thank you for your help.

So the porcelain one is also Vacor? So both marbles I posted - the asteroid and the porcelain (is that the proper term?) - are Vacor?

Sorry about that. Not sure where my mind was when I was measuring and posting. My caliper readout was flashing at the time. I also should have known better. Changed the battery and get .63. Thanks for all the help everyone. The kids get this one!

Thank you.

A second marble. Appears to be pottery/porcelain(?). Appears to have been hand designed from crudity and non-uniformity. Measures .49-.50" with a caliper. Surface is kind of crude and wobbles when rolling. Can be positioned so looking down at the top shows an upper hemisphere with alternating blue and white triangles with their points meeting at the apex of the dome. The bottom hemisphere is the same, but its pattern is rotated so the bases of the blue triangles on top touch the bases of the white triangles on the bottom. Any info on maker, date, history, and collectability appreciated.

I have experience in collecting glass insulators and bottles...so why not do marbles as well?😊 I came across a couple - giving each its own post - the other day and am thinking this glass one is an older one. I just don;t know whether or not to throw it into the play pile for my young grandsons or set it aside as something more valuable than just a toy to be lost. "Valuable" meaning history as well as collectable value. The first measures .21 to .24 inches taking various measurements with a caliper. It appears to be white milk glass and feels a bit crude. Maker? Date? Any help appreciated.
