Randy nobody said it wasnt a hazel atlas jar.
If it has the mark, it has the mark.
And it may fit a Dr.Berrys box.
So?
I have a Velvetine Hazel atlas jar that will fit as well.
Same jar, but in milk glass.
That means nothing.
Also, I explained why platonite was patented in 1936.
That was for plates and dinnerware.
Not cream jars.
Platonite was a new process that allowed milk glass to be layered
with other colors, such as red stripes, for decorations.
The point being, as you found, milk glass was THE predominant glass color by at least 1900 for ointment jars.
It's hard to find a clear one made between 1900 to 1950.
Clear ointment pots generally show up in catalogs in the 1890 to 1900 time frame.
Milk glass was so common, as early as 1905, that Hazel atlas, in their own catalog of Ointment jars titles their book " Opal ointment jars..."
That was from a catalog in 1926. And apparenty opal glass was used long before then since the Hazel book I found made in 1926 was the 7th printing!
They don't have a book listing clear ointment jars.
Now it matters not whether another company used clear glass for their ointment jars.
The fact of the matter, is that Hazel, our examples company, had pretty much phased out clear ointment jars years before AE's flight.
I cannot say for certain a run or two did not happen with clear glass.
But given it's been two years of research to locate one print ad from the 1930's showing a clear ointment jar from HA, I would say the odds are great few clear ointment jars were produced in the 1930's from this company.
Therefore, a clear ointment jar from Hazel Atlas points to an earlier manufacture date, most likely before 1920 and probably a decade or more earlier than that.
Meaning the found jar was much older than the 1937 flight.
So the jar doesn't fit, this "evidence" you must acquit.
