Hello all you pontil people. I started a post and got about half-way through it’s creation when I hit a wrong key and lost my work. “Dar n Computers”. Anyway, I have a blog for my homepage that was started a few years ago and I am still not satisfied enough to put it there. I had listed some of the key book references and was just starting to discuss the various pontil marks when I lost it. “Ba Humbug”. My objective was to point out some information regarding the punty rod types and the contact material application that resulted in different pontil marks. Ø The punty rods were made different for many different size bottles and contact. The intent was to put the handle on a hot first stage bottle for the neck finish application; tooling or what ever had to be done while they used a handle to hold it. Ø The ends of the punty rod were designed for the job. And some were flat on the round end, domed to fit a bottom, tapered to fit a push-up, what ever was needed. Ø The working end of a punty rod was heated. so it wouldn’t shock cool the bottom of a bottle in the process. I am sure they had them laid near or nearly in the glory hole to heat them. Ø The first thing they did was put an attaching paste on the contact end of the punty end, that they were going to use. This paste, as far as we know, was graphite, red lead, or white lead. Ø From there they had working wooden boxes in a line with segments that contained: sand, glass dust, glass chips, and powdered iron (from the machining of mold iron). Ø The paste coated rod was rolled or dipped in these materials depending on what the bottle maker liked to use or depending on what would hold the size of bottle he wanted a handle on. Sometimes they just rolled the outside edge of the punty face to attach it to the bottle being made. There just isn’t enough written about these methods. I have visited the Corning Museum and obtained some help getting description of these methods being used, but the early bottle books didn’t spend much time covering such a mundane detail. I hope this will help your understanding – from my limited knowledge. RED Matthews
