Sounds bananas, but I bought a bag of marbles for $12.50 today, and so this probably isn't an Atmosphere... but, is it?
It was in a bag with some clearies/solids, some modern Asians, and some from House of Marbles... which may be where the Vacors came from. At least 5 of the marbles are Vacors I believe - they have the orange peel texture and/or I found their names, including a 22 mm (7/8") Dragon, and 35mm (about 1-3/8") Frosted Rainbow, Oily, and (pretty sure) Jupiter. Pictures of those are included at the end, but the one that I'm wondering about is this 35mm (1-3/8") boulder with orange peel texture. Could it be an Atmosphere or is that just wishful thinking? Of the types I've seen discussed on Stephen Bahr's video about Atmospheres, it's most similar to a wave-type. Any Vacor experts able to weigh in?
