Some Cambridge blanks (plain glass shapes) can be hard to tell apart but you won’t mistake Martha! Cambridge line 4600, aka Martha, is frilly where most other lines are more plain, content with curlicue handles or keyholes or slightly scalloped rims.
Take a good look at the sugar bowl above, the rim is scalloped with two sizes of curled frills, handles have 3 curlicues, the base is enlivened with rings of rays and the sides are paneled. This is Martha, those curly frills are unmistakable!
The candle holders are even fancier. This 2-candle holder has the Chantilly etch, most appropriate. The candle holder base is plain (about the only part that is) but the arms have little curled nubs that spiral away from the curve and the candle cups bases have rays similar to the sugar bowl base while cup rims are frilled. It is stunning with lit candles.
Plates are the flat version of the sugar bowl. Notice the exuberant scallops and the same rays in the center.
Cambridge didn’t have a stemware line specific to blank 4600 but used this line for plates, serving pieces and accessories. For example, here is the 2-handled relish dish, again with the Chantilly etch. The rim is curved but instead of the frills had little impressed beads and the handles are also more plain. (No one would call Martha plain!)
This comport, Chantilly etched, shows the same dramatic scallops, rays and a stem with restrained curled nubs somewhat similar to the candle holder nubs.
