Machine-made bottles tend to have few if any bubbles in the glass and the thickness of the glass is usually more uniform throughout the bottle as compared to mouth-blown bottles.

This is especially true of later machine made bottles, i. The presence or absence of bubbles in the glass and relatively even distribution of the glass throughout the characteristic is not a primary feature of either machine-made or mouth-blown bottles, though there are strong trends. What these Diagnostic Features Indicate: Bottles with all the noted primary machine-made characteristics 1, 3- 5 including the suction scar on the base point 5 above and picture to the left can date no earlier than and are usually post Though patented and first used to a limited degree inthe first Owens Automatic Bottle Machine licenses were granted to other manufacturers in late making the effective "beginning" i.

This is accomplished so that there is no perceptible mark upon the bottle showing the joint, and the bottle stands every possible test as to strength.

See the pontil scars page for more information. The blowpipe style pontil scar puts the date of this bottle as no later than approximately and does indicate that it could date back to or even before.

The embossing on both bottles is relatively flattened and not particularly "sharp.

The picture to the right is a close-up of both bottle finishes. It shows that the side mold seam on both bottles stop well below the top of the finish. On close observation it is apparent that neither bottle has a ground down top Duraglas milk bottle dating to the finish.

This question deals with whether the base of a bottle has a pontil scar, and if present, what type of pontil scar. The pictures below show that neither of these bottles have any evidence of a pontil scar on the base.

Click on the picture above to see more distinctly where the side mold seams end on the two bottles. This is the point in the Dating key where our two bottles diverge from each other.

Bottle "A" has a side mold seam that distinctly ends right at the base of the finish. There is also a "drip" of excess glass on the left side of the neck that appears to have flowed from the base of the finish onto the upper portion of the neck. Given these two diagnostic features, the answer to Question 5 for bottle "A" is option A - this bottle has a "true" applied finish which very likely dates "A" as no later than to We now have narrowed bottle "A" down to a high probability date range between and Bottle "B" differs from "A" in that the side mold seam ends a quarter inch below the lower edge of the finish and there are horizontal, concentric tooling rings around the upper neck and finish "wiping" out the mold seam.

If one looks closely at the middle portion of the neck on bottle "B", there is a slight bulging out towards the outside of the bottle of the inside glass surface. This is a common feature resulting from the action of the "lipping" or "finishing" tool. This bottle clearly has a tooled finish which makes option B the correct choice for bottle "B" under Question 5. Inthe Owens Bottle Co. Currently the company is the largest manufacturer of glass containers in North America, South America, Asia-Pacific, and Europe, with 79 plants in 21 countries.

The symbol, seen in the pictures below labeled Exhibit B and Exhibit C, contains an I inside an oval with an elongated diamond superimposed over it. Sorry I don't have better pictures, the glass is quite old and had been in the water for quite some time. The symbols, therefore, are quite faded. There is no exact year in which production of the symbol stopped, as various plants ended use of the mark at different years. Source Now, I know from the use of the symbol on the glass that both pieces pre-date the mids, but is there a way to narrow that down?

The general rule when dating glass with the O-I symbol is the number to the left of the symbol is the plant code, and to the right of the symbol lies the date code. Other numbers, such as the 7 in Exhibit C, are specific to the production plant, and letters, such as the A in Exhibit E, usually stand for the glass model e. In other words, they're not very useful for our purposes. The number on the right is our year code and what we are most interested in. The year code for Exhibit C is clearly a 9. In conjunction with the relative dates of the symbol, we know that the 9 could either stand for or is possible, but very unlikely.

By the time came along, the company realized year codes were beginning to repeat, so in the 40's they implemented adding a datimg after the bttle code to indicate years By the mid's most plants switched to using a two number date code such as 46 for a production year of However, use of the period after the one number date botttle in the 40's, and use of the two digit Duraglae code was bottlf used bogtle various production plants, therefore the 9 alone doesn't always mean with absolute certainty.
