yeah, steph is right. they did make both during that time period. sorry about that!....
but what's weird is going thru copies of old documentations and catalogs... time lines are sketchy! and they say the same thing in advertising about carnelians as they do the cornelian. almost word for word!
we do know MOST of the swirly types, the ox bloods, silvers, blues, etc were pre cork right?
the time line as we understand it, and everything can of course overlap, is the handgathered types, then the slag types, then the moss swirls and then corks and finally patches. and I made the mistake of 'carnelians' vs 'cornelians'. DUH! sorry... :-)
oddly enough too, just an observation, many of the early ads and catalogs we have do not have dates! very frustrating! and there's a few boxes in books we know were backfilled and not original. so i think general rules are the only thing that's going to apply unless one has ordering pages direct from the factory, with dates. sure would love to have a few boxes of that stuff, but alas, mostly long gone. akro was famous for quality control, but record keeping? naw....
lol
