Comments on: Chilling the Cavity of Cast Iron Bottle Molds http://www.bottlemysteries.com/2008/08/who-why-and-when-cast-iron-bottle-molds/ Information about rare and collectible glass bottles from a member of the glass bottle mold manufacturing industry.

I came upon this mold chilling and now have a greater understanding. My question though has not been answered. I have lead patterns of bottles and was told these were made in the process of making the mold. I was informed that in the process of making a mold, lead was poured in then remelted to use in the process of making additional molds. I have put together an exhibit of recovered material from the Whitney glass works in Glassboro NJ. There I have located a number of mold warmers made of glass. These make sense. The lead examples I have are from WTco in Millville NJ. Whitall Tatum. Also from that house I have wood examples with the glass house prints. I purchased the items to include in my future exhibits and would like to be accurate as to their use. I have considered that some enterprising individual has the Iron mold and simply cast lead and came up with a story. The patina on the lead looks legitimate, but you never know. Anything anyone could tell me would be greatly appreciated. Hi! I came upon this mold chilling and now have a greater understanding. My question though has not been answered.

Your cold mold ripple is the same type of process/problem that I have in my production of silicone rubber molds and polystyrene resin, that's how I make reproduction scrimshaw. We have always called that effect: orange peel!!!!For years we have had to preheat our molds and outgas them for a time prior to using them. We just accept that as part of the process. Enjoyed your discussion and will pass this website on to the antique bottle collectors that come to us on Cape Cod. Love to learn about new things. Thanks.

I will hope to look when I get my hands on it and advise you then. The wavy thickness of the glass happens when the glass is blown up against the molds inside surface - but the coldness of the metal keeps it from blowing against the molds surface to an even thickness. Thus distorting the light with it's thick and thin glass in the glass. Thanks for the action this has brought up.

It never dawned on me that "chilling" was an intentional process, rather than a random effect due to a cold winter morning's first few bottles blown. It's especially valuable that you came to this conclusion while working in the industry itself. Doesn't leave much room for doubt!
