richsantaclaus Posted December 24, 2010 Report Share Posted December 24, 2010 Nancy - can you shoot more pictures of that cool marble - I can't really tell what I am looking at - thanks. I only have seen gold, green, blue and purple aventurine that comes in chunks lately. I bought some of all 4 colors in Quartzite, Az and I was told by the owner of the rock shop that they came from a local collage where they teach glass blowing and it was the cullet left over. It seems that this cullet has 4 distinct categories of results from my experience of contemporary marble making and including it into my marbles by applying the aventurine to the exterior surface: 1) it "spreads" out and makes little dots in the marble's pattern (it bubbles under the heat). 2) it stays evenly spread in the stringer pattern I laid out on the surface of the marble (like the spiral of a corkscrew). 3) it "glumps up" and makes a thick spot and kind of settles into one spot and sinks into the interior. 4) it "pops" and thermal shocks and is very difficult to work into the marble's design. My experience at the torch might resemble the problems that were presented to the machine made marbles of old. Since they wanted to do mass production, I can only guess that the current problems I am having with the aventurine is consistent with the problems they were faced with back then. I further guess that this is the reason they didn't use aventurine in mass producing marbles for 2 reasons: one is cost and the other is usage/application was difficult. I wonder what your thoughts are on this matter of not seeing vintage marbles with aventurine inside them or in their designs. I also ask you to stay on topic and join me in the adventure of brainstorming and learning - thanks! Rich Link to comment Share on other sites More sharing options...
