My wife's family was in the mineral business back into the 40's and 50's and she told me her dad had a big table full of the multicolored slag glass. I can't conclude their material is anything other than manmade glass.ġ3th Sep 2016 14:04 UTC Rolf Luetcke Expert Steve and all, And we know that flintknappers were using slag glass to shape arrowheads and the like during the time when Carol's ex acquired the material. They were usually 50 cents each or sometimes four for a dollar.Ĭarol's and Steve's bright red material is unlike any known variety of obsidian, but it is identical to well-known slag glass. I don't remember when I got the smaller point, but it was likely picked from a basket of modern-day arrowheads offered at a rock show during the same period. In other words, it was common during the 70s to see arrowheads, knives, and similar pieces newly-made from glass. He had a supply of several colors of slag glass, including chunks identical to the material posted by Carol. As was common at rock shows, the maker was demonstrating his flint knapping skills at the show, and selling what he made. I bought the larger of these two "arrowheads" from the maker at a rock show in Utah in the early 1970s. You might even try to cut it just for keepsake. I hope at least you hold the interest and memory of your grandpa. Sorry friend if this isn't what you where hoping for. I would keep it for that reason alone and display it alongside my best pieces. It is always a dissapointment finding out something you held for years is leaverite, or manmade in some way, but at least you have a memory with it. I bring in so much it needs to be weeded out anyhow. In fact if you want I can send a flat rate of labled stuff I have collected along the way for free if you pay shipping. I like to make arrowheads with it and have plenty laying around. If you wish I can send you a small parcel of mahogany obsidian. Fortunatley at least you have a memory to go with it. How slag got to be in such a remote desolate area I do not understand, but slag is slag. To lighten your feelings, I roamed the desert of west texas as a yough and found bags of "meteorites" over the years.
