DGCo JARS


There can be no doubt that these are made at the Diamond Glass Co. 1890 - 1902 . 
The engraving style used on the logo is a continuation of the EGCo , NAGCo & DARLING double line logo
This doesn't mean they were made to the end of the 1902 but that was the years the DGCo used that comany name. 
It though seems to me they may have gone all the way to 1902 and at that time swithched this type of  jar production to the BEST trade mark that they had purchaced by aquiring the Early Dominion Glass Co Ltd in 1897.

Their first BEST jars would have been the smooth lip smooth base with an overseal lid ( these smooth lip overseal jars are under valued )

DG Co


There are 3 moulds in each of the sizes , but in each size 2 of them are quite similar , this is the reason for the multiple measurements.
Two moulds are reworked with base #'s added , this gives 8 jars for a set not counting colors.
The term coarse ribs or fine ribs has to do with the distance apart of the ribs in the D .
