Mould-Blown Bottles

Mould blown bottles are blown into a mould by the power of someone's lungs with no aid from compressors or any other machines - just moulds and tools. There is a lot of information out there regarding mould blown bottles.

Finish Forming Tools

Recently, I've been looking for information on finish-forming tools. I can't find a first date that they were used, but I've been looking at patents and found a few. In one place the SHA website states that the earliest finishing tools were likely the 1870s, but they also state that it was after 1855. They may have been earlier in Europe. The earliest patent I could find on the Google Patent search was for patent 13,402, and was a tool that formed finishes is dated August 7, 1855 was for "certain new and useful improvements in tools for forming the orifices of glass, earthen, or other bottles ..." Indicating that such tools existed prior to 1855. The improvement was for "forming screw-threads in the necks of glass bottles and similar articles". 

One source with no citations states that the finishing / lipping tool was first used in England around 1830 and in the U.S. around 1850.

A mould-blown bottle will have a single set of seams with no ghost seams or scars (C), and will have an applied finish that is irregular (B) and might have horizontal striations from the finishing tool.
