Miscellaneous body features NOTE: If unsure of some of the terminology used on this page related to the physical features of bottles, visit the General Bottle Morphology page. That page includes an illustration of a somewhat stylized "typical" bottle with the different physical "parts" morphological features pointed out; parts which are often easier to visualize than describe. Manufacturing non-mold Based Body Features Free-blown bottle bodies Free-blown bottles were produced without the aid of a mold, being instead formed and shaped by the skills of the glassblower using manipulation of the blowpipe the use of which dates back to the 3rd century B.
History[ edit ] A very early hand dimpled soldered cylinder thimble A single steel needle from the time of the Han Dynasty ancient China BC — AD was found in a tomb in Jiangling , and it could conceivably be assumed that thimbles were in use at this time also although no thimble seems to have been discovered with the needle. The earliest known thimble — in the form of a simple ring — dates back to the Han Dynasty ancient China also and was discovered during the Cultural Revolution of the People's Republic of China PRC in a lesser dignitary's tomb. Oddly, neither the Romans nor the Greeks before them appear to have used metal thimbles. It may be that leather or cloth finger guards proved sufficiently robust for their purposes.
