how do you date these old beer bottles anyhow? They sure are heavy and sturdy in comparison to what is on the market today.

Hey unclemac. Good question on the beer bottles. Wish i could answer it for you. Have you been on the beach lately?

Trademarks & Manufacturers: Owens-Illinois Glass Company

Hey unclemac,

If I'm reading the first one correctly: 21 <(I)> 5 the plant # is 21, for Portland, and the date would be 1965. Is it, in fact, a "21"? By 1958 most of the Owens Illinois marks had been changed to the simple "I within an oval O." See Owens-Illinois Glass Company

The second Duraglas example appears to be: 4 <(I)> 41 I'm unsure if it's a 4 with a dot that got mixed up with the knurled design, or an actual 41. You know how those knurly guys can obfuscate a good story. It would mark it as one of the last of the millions produced at the Clarksburg plant, depending on when the actual closing date was.

There has been some recent discussion at the A-BN regarding the accuracy of these charts. OWENS-ILLINOIS CHARTS ~ HOW ACCURATE ARE THEY?

thanks as always surf....I pass over a lot of old beer bottles on the coast but these two I found to be really heavy and sturdy. There are no doubt a million bottles tossed off boats and such under the sea slowly making there way to the beaches.

....why yes as a mater of fact I have....here are a few pictures of some curious sites along the coast.... notice the old shellfish beds about 20 feet below the current surface....I have heard they are about 80,000 years old. And here is a great old skeleton of a wooden boat too. Been finding some great stuff, but no interesting bottles.

Thanks fir the photos unclemac. Never get tired of seeing your beach. I'm sure fossil hunters would be very interested in that shell layer!

 

[unclemac]

the strange thing is that the shells are still intact. It is a matrix of shell and clay now. The beach sand is a mixture of this really old ground up shell and mineral grains. On some areas of the beach you are walking on and crunching up this layer. Now and then in the past I have taken out clumps of the clay, peeled off the shell and fired it in the kiln...they make odd red ceramic "fossils".
