  1. A loss to the community. Met him for the first time in Amana. He had a passion that can't be replaced. -John
  2. Great illustrations! What would be nice to know if the illustration and the furnace geometry were to scale. I speculate, no. What is not explicitly stated in the text is the exact location where colored glass is added. I would not expect this to be divulged, since it could be a matter of trade secrecy. What we do have from 25 is: "and could be put in different places in the flow-tank of clear glass." This tells us that the location placements were selected to give different results. -- One thing that has to be considered in the furnace are convection currents. These cu
  3. When making marbles, it is about statistical distribution of outcomes. The lawsuit documents discuss how Master added color to the glass without the benefit of a controlled injection like the Freese patent (Akro). What I have not seen are the visuals showing where Master added their color to the clear base. Molten glass has to behave under the laws of physics (thermodynamics, fluid dynamics, etc.). I speculate that the color was added in the same location at consistent intervals nearest the forehearth nozzle. The shorter distant will equate to lesser time that the glass is
  4. No, mechanical graining of plates is different. Graining is to provide a uniform rough surface for ink to adhere. A smooth plate would allow the surface tension of the ink to "ball up" like a bead of water on a leaf. The rough surface allows the ink to wet the surface and lay evenly. https://www.polymetaal.nl/beguin/mapg/graining.htm John

  6. Fred, Welcome! That "pontil" mark looks like it was made with a diamond shear. The 1-1/4" diameter size is about the right size for a Chris Robinson "Road & Tunnel". However, without seeing it in person, I may be wrong. If Chris pops in, he would be the best judge of his work. Reference this thread: https://marbleconnection.com/topic/23119-rare-road-tunnel-slag-on-ebay/ John
  7. Marian, Plan on going. Chad puts on a great show. There are many people that collect and sell marbles that do not post on chat boards. You will find many great people at shows that are willing to share their knowledge. It s nice for you to actually see and hold a marble to discuss and purchase (unlike online auctions). There are two presentation venues at most shows. During the week, people setup their marble collections and wares in their hotel room. It is fun to walk from room to room looking for that "something special". Then, at the en
  8. Photo by Zaboo. Marbles and Box by Bo Stiff. Bag by Sue Cooper. John
  9. I can't say if Bo was the first, exclusive or one-of-many that made Micro or Mini Popeyes. What I think he did best was making mini Popeye Box sets. I believe Sue Cooper sewed the mini bags for him. Maybe Steph can find some photos. John
  10. Alan, Thank you. I was hoping that you saw Dan Ambrose make them with a copper pipe. Like a personal witness to history. I remember hearing stories of people doing marble making demos in hotel rooms with carpet. I think those are the "good ol' days"? John
  11. Alan, That is neat. Never seen the tube used before. Just to be clear, are you saying that is how Dan Ambrose made those or how you saw another artist make theirs? I've seen (and made) them using the cane/drip technique and murrini technique. Never used a tube. Bo Stiff made awesome popeyes. Maybe someone saw him make those and would comment. Thanks! John
  12. My condolences to family and friends. Whenever someone passes, I like to read their old posts. It never fails to bring a smile. I got a chuckle with his joke about 4 marble collectors in Cambridge. Go look and enjoy his posts! John
  13. Corundum mill balls are molded and heat fused for strength (sintered). The molding process leaves a ring around the equator. This ring wears down/off as it is used. https://www.unionprocess.com/grinding-media.html#nonmetallic This is just speculation, but I looks as if someone attempted using enamels to decorate the surface. https://thompsonenamel.com/ To make the powder enamel stick to the surface, it is mixed with a wetting agent to become like a paint. The lack of surface porosity of the ball mill resists the attachment or even spreading of the enamel paint. Henc
