Indentifying Bottle Glass

Bob Sonderman

On October 11 Bob Sonderman gave a mini-workshop on identifying 18th through 20th century bottle glass based on determining how the bottle was manufactured.  Bob even had examples of bottles or bottle fragments to illustrate the different processes.  So we could hold the bottles and look for the mold seam or the sand in the pontil mark.

Several people brought bottles.  In some cases we were able to identify their bottle based on information from Bob's talk.  For the other cases Bob was able to tell us about the bottles and their probable manufacture date.

Robert Sonderman is Curator/Director of the Museum Support Center for the National Capital Region of the National Park Service.

Bob is quite knowledgeable about bottle glass, and we would like to thank him for coming to Charles County and sharing some of his knowledge with us.
