Has anyone ever saw any of these?

[Rick & Carrie]

Does anyone know what these jars contained? How uncommon or rare are they?

I don't know what they contained but I would guess they are common. Leon.

They aren't common. I have yet to find anyone on any group or forum that has saw such jars.

The NW jars are scarce. 90% of all known Northwest Glassworks makers marks are from the bottoms of amber beer bottles.

Northwest did make mason jars, both in regular mouth and wide mouth, but they are marked "NW Electroglas". I believe these are product jars; some appear to take snap-on lids commonly used for pickles & olives & other condiments. The ones that take screw on lids are still likely product jars. Maybe not terribly common as Northwest was a fairly small glass company, but still not of great value imho.
I'm attaching photos of my NW Electroglas jars in case those are of interest.

maybe I shouldn't have commented. I don't specialize in 1930's, 40's or 50's screw top jars, or any jars. I do like my C.F. Spencer wax sealer jar from 1860's though. Leon.

Does anyone have a picture of a snap on lid to share?

I wonder if called Electroglas because of it's new method of melting glass by using electricity? Leon.

We have a few intact snap on caps that we have collected while out digging. We'll get them out, take some photos, and post them here.
