DATE CODES DISCOVERED ON MILK BOTTLE RIMS: A WEST COAST DATING SYSTEM.

- Abstract
Some embossed milk bottles in the western United States exhibit manufacture date codes that aid in the dating of historic trash deposits. Further research determined that these tiny embossed digits on the top of the finish rim represent a unique date code, indicating the month and year of production. Examination of more than 1,250 milk bottles (230 with codes) demonstrates that these codes were used by five California glass factories between 1923 and 1933. The coding system was initially developed to help dairies track bottle loss and was quickly adopted by glass factories to compete for dairy business. The practice was discontinued when one glass company dominated the market.
