Getting some of my stuff out of the garage and back on the shelves where they belong! Thought I'd share some pictures of my favorites I had packed away. 4 South Jersey blobsChas G Franck Wheat Road Station, J.W Kirschoff Bridgeton, N.D Pasquale Main Ave, A Matinelli
Neat bottles you have shown us. I am onto a kick of bottles that were made in the three mold method. They fascinate me because when the bottom cup mold piece was made, they couid not chill the iron casting hole mold wall cast iron. But they could chill the shoulder mold cavities. This created bottles with cold mold ripple in the lower portion glass solidification. Chilling the iron creates a dendritic carbon structure in the iron the glass touches. This causes the mold surface to stay hotter and the glass harden more uniform in thickness. The unchilled iron moves the heat to fast in plain iron with scattered carbon clusters. RED M.
Thanks Red! Some very good information there on 3 piece mold bottles! As far as uniform in thickness, I've noticed out of all the bottles I have, the most invariable bottles as far as thickness goes are hutter blobs. Very little changes texture wise, but other smaller glass companies that produced blob tops and other closures aren't as consistent with the quality of the bottle. There will always be minor imperfections with any glass company but out of all Hutter blobs are made the best.
