Knox Glass Bottle Co. Pharmacy Bottle of 6 Drams.

 

Graduated Pharmacy Bottle.

I've found tons of these kinds of pharmacy bottles that were made so the pharmacy could affix their own paper labels.  They are one of the most common types of bottles, and not nearly as nice as pharmacy bottles bearing embossed labels showing the name of the pharmacy.  They come in a wide variety of sizes, and I've posted a few of the other sizes.

This one has a bottle maker's mark on the bottom.  It is a J in a Keystone.

Bottom of Same Pharmacy Bottle.

That is hte mark of the Knox Glass Bottle Company, used on containers made at their Jackson, Mississippi factory location (1932-1953). 

J in a Keystone (1932-1952) The Knox Glass Bottle Co., Jackson, Mississippi, used the J-in-a-keystone mark (Figure 5) from its inception in 1932 (Toulouse 1971:271) until 1952, when Chester Underwood was ousted, and all plants switched to K in a keystone.

So that pretty well dates this bottle to a twenty year period as well as the plant where it was manufactured.

On the shoulder of this bottle is is the following mark.

Mark on Bottle Indicating 6 Drams.

The first mark, which looks something like a "3" is the symbol for dram, a measure of volume.  A dram is 1/16 of an ounce (1.772 grams) for weight or 1/8 of a fluid ounce (≈3.70 ml) for liquid.

The mark indicates the total volume of the bottle, so the mark indicates the volume of the bottle is 6 (vi) drams.

I've some bottles with smaller pharmacy bottles as little as 2 (ii) drams.

Pressed Glass Decanter by Thatcher Glass Mfg. Co.

Pressed Glass Decanter.

If you hunt bottles, you'll probably find a few decanters - not often but occasionally. The decanter shown above was found along the Indian River.  It is about 9.5 inches tall and in perfect shape.  The top is perfect.  It isn't chipped, the bottle was made with an irregular ruffled edge around the lip.  It looks fine sitting on a windowsill reflecting the morning sunlight.

There are no marks of identification on it except on the bottom, where there is a good amount of information.  You can see that below.

Bottom of the Same Decanter.

Most prominent is the FEDERAL LAW FORBIDS SALE OR REUSE OF THIS BOTTLE message encircling a variety of other marks that need deciphering.  

The Federal Law message dates the bottle to somewhere in the range of 1935 to 1964.  One of the other numbers on the bottom is "62" which could indicate a date of 1962.  I haven't yet done enough research to decipher all the marks, but I think I could find the information. I know there is probably a factory code (probably the D), a mold number and some other things.

Below is the maker's mark displayed in the center of the bottom.

MTC Maker's Mark on Bottom of Decanter.

A little research revealed that to be what is referred to as the MTC mark - one of the variations used by the Thatcher Glass Mfg. Co.  Thatcher was referred to the father of milk bottles.  He didn't invent the first, but was responsible for many of the early innovations and did a lot to make milk bottles "the" method of delivery.

Here is a link for a lot more information on the Thatcher company.

The extent of the available research on the company is impressive.  It is the kind of research that is not produced by big names but to a large extent by devoted enthusiasts who are as systematic and detailed in their research as any top name scientist.

I think the linked site will help me decode some of the other numbers on the bottom of the decanter when I devote the time to it.  

Here is a link to an article that tells how to tell the difference between pressed glass and cut glass.

When you do find a decanter, you never find the stopper at the same time, but usually find enough lost stoppers to be able to find one that fits and looks good.
