Differences in Egyptian Pattern footed individual berry bowls

I have four individual berry bowls in the Egyptian pattern. There are slight differences in coloration of the glass (some more purplish than clear), but last night I noticed that the footed stand on three of them has seven indentations (divisions) and on the fourth, only six.

Would those differences indicate a different manufacturing time frame?

Thanks.

 

The color difference sounds like sun-purpling - manganese (I think) in the glass that turns purple with prolonged exposure to sunlight.

 

Molds wore out as they were used over extended periods. Sometimes in retooling the mold the patterns were slightly simplified. That may be what happened to your fourth bowl. I think moreotherstuff is correct that some bowls were exposed to more sunlight than the others and as a result purpled.

 

What? No pictures????

 

Sorry for the delay in posting the pictures. I counted wrong the first time; there are six angles on one and eight on the others. The one with six is ever so slightly larger also.

 

Here they are FULL SIZE....

missed seeing this one earlier...

from what I can make out this is Adam's Glass Co. #50 Sphynx, c1882; AKA: Egyptian
the facet/panel differences may be due to size or use/designated form. berry bowls were made with and w/o a foot/pedestal. there was also a set of footed bowls/low compotes. So it may be you have a footed berry and a similarly sized low compote.
the purple is from one piece having more sun exposure over the years; perhaps displayed in or near a window.
