lol....it's just sometimes hard to get excited about marbles. Lately I am more interested in tall, thin, well educated, long haired females...hahaha
There is no big mystery as to what MFC manufactured. The archaeological record supports the sales literature beautifully.
I'm not glossing myself...but I easily have over a thousand hours of unique marble related research under my belt - none of which involved reading an existing marble book in print or collecting the damn things. The history, story, and technology behind the subject is what interest me the most....I can actually care less about the marbles themselves....lol
My largest example of PT coloured glass was excavated at Navarre....this is where Leighton showed MFC certain colours of glass and also where the MFC machine was first tested.
We have all seen dug football rejects right? Here's one from Navarre along with a very rare orange machine made marble....the earliest documented machine made marble in existence :-) Peter had a large opaque orange example just like this. This color is the same recipe as oxblood...I have made it before.
BTW....MFC did not make red slags...lol This is one cuppy cake I am sick of telling. The MFC book has been rewritten, but we keep finding new information! Last year I acquired two new images of Harry Heintzelman and other workers at the MFC plant.
Thank you Hansel for everything you have shared with me - I have been lucky enough to see all of your wonderful artifacts with my own eyes. I would love to be locked in your marble library room!
