Thanks Hansel for bringing that up, And Gnome, when it comes to OXBLOOD GLASS and glass with an oxblood color we are talking two different things. This helps keep an already fairly muddied topic from getting even more muddied. Oxblood colored glass is not necessarily Oxblood Glass. Although there are some very early Marble kings that have a very Oxblood looking streamers in one of the patches it does not even appear as genuine OXBLOOD GLASS . Spidermen being the most common. And yes many marbles made by German makers MFC and Akro purposefully made an OXBLOOD GLASS. I also believe that on occasion a true Oxblood Glass can be accidentally formed usually in association with a blue-turquoise glass color. I do not believe that is OXBLOOD GLASS on that MK. And it does seem you are saying any Oxblood colored glass on marbles should be called Oxblood. That just not the case. We need to have a line some where. Calling it Oxblood colored glass works for some folks but I do not even like seeing that.
No blinders on here Gnome. Just an almost 30 year collector trying to keep his hobby getting even more confusing an muddied for new and even old collectors than it already is.
