I've seen a few of these very early "custom" Weber kettles over the years, and always wondered about the unique finish. Some call it "spiderweb", or "splatter". Most of them appear to be black kettles with white or greenish-yellow squiggles, but they made other color combinations. So what inspired them to do this? One answer may come from the Brush-McCoy Pottery Co. From 1911 to 1925, Brush-McCoy made some very unique pottery, but mixed in with the usual colors and shapes was a finish they called "Chromoveil". Fast forward to 1956, when Weber introduced their own version of this finish with the "Custom". Both 18.5" and 22.5" kettles carried this unique look for a short time. Each one is unique. I can only imagine the person who was charged with applying the "veil" to these kettles. As luck would have it, one of the vintage photographs at the Weber Grill restaurant in Chicago shows Bob Krug introducing this unique kettle at a live cooking event. The inscription refers to the finish as "Chromavale", but I suspect that was a simple misinterpretation of what was likely word-of-mouth history. The picture here shows a beautiful 18.5" "Custom" kettle owned by a Chicago collector and a range of Brush-McCoy pottery with this amazing finish. (Even a pink one!) If anyone at Weber can add to this it would much appreciated.
