I own a number of them and there is no sign of a white base/color veneer. I suppose I could crack one open... The glass color appearance is strikingly different than vintage P&R MK types - it comes across as much more glassy. All of the MK "remakes" of those types appear that way.

(Unfortunately, I have chosen to remove this ID content due to unchecked behaviors by others on this board. My apologies to those who will not benefit from it in the future.)

I would be happy to buy mint Spidermen with oxblood for $20.

You cannot truly heal a fracture. You CAN treat it to make it visually less obvious - but don't mistake that for returning it to its original strength. The treatment (IIRC it is a form of optically clear epoxy) costs enough that it isn't worthwhile on a $20 marble. Do not temperature shock (either direction) a marble with a partial fracture or annealing plane. It can pop in an instant.

Those are some cool MKs you have there.

I'll comment that some of these recent monthly color "themes" seem to be bordering on the very complex to the point of excluding many on the board from participating. I would urge those who plan to be so specific to consider that complex, hard-to-find color concepts may be seen as creative - but they are also very exclusionary. Marbles meeting the above criteria have to meet 3-4 tests.... "snowy mica" not being a minor one by anyone's measure. I may be misunderstanding the intent of these threads - and perhaps the desire is for them to be small, with limited contributions from board members over the period of a month. As an earlier poster noted - I don't think you are going to get much participation...and when you do it will be contemps (which not everyone collects) and handmades (ditto). Respectfully, Alan

A specific combination of TWO colors is pretty specialized and may make for a quiet thread for a month - kind of like the "gold" thread.

They look to me like patches from a beginning or end of run that are missing a second major color component. Personally I wouldn't give them a seperate name as if they were a discrete production item....they appear to have been discarded because one glass color pot wasn't flowing.

True gold will be hard to find (IMO). Here is some silver metallic: Josh Simpson:

Your understanding is correct.

Deep red glass was originaly formulated with gold dissolved in an acid. The same was true (IIRC) for pink - just at a lesser amount of gold. Not all reds required the use of gold. I think that the use of gold was discontinued in the 1930s or 40s by using selenium - and later a copper formula... both which were cheaper. U.S. marble manufacturers would have been restricted from using gold during WWII.
