These sites are all adjacent to one another along the same road, so availability due to transport shouldn't have been a primary factor in the amount of flat glass on each site. I suspect the most likely route would have been overland via the Maysville Road and to the road via river traffic on the Ohio, though some glass could have come via the Kentucky River and Frankfort - there aren't many options for river travel where the sites are located. Our first railroad, the Lexington and Ohio, wasn't operational until 1833 and didn't actually go to Ohio. It eventually found its way to Louisville but that wasn't until 1850 or so and by then, my sites were pretty much abandoned. I've found references for glass factories in Louisville, but they post-date site abandonment as well. There were glass factories in mid-Ohio by the early 1800s, but I don't know if they produced flat glass - they seem mainly to have been involved in bottles. Anybody ever compare CCI values to frequencies of window glass on multiple historic sites? Daniel B.

Can anyone direct me toward references for early 19th century window glass in the eastern US - that aren't for dating the associated structures? Specifically, I'm looking for information on price and availability and operating under the assumption that more window glass on a site for this time period will directly associate with a higher socioeconomic status for the site's occupants. I've got 4 sites in central Kentucky that date from around 1790 to 1840 and based on the excavations to date, there is significant variance in the amount of window glass from each site. I'm guessing the window glass types would be blown plate, crown, or cylinder glass though I don't think there's a good way to separate the types. Thanks, Daniel B.
