RE: Albany Glass Works
The glass works was actually located near present day Albany in the town of Guilderland and was known as the Hamilton Glass works . It operated from the late 1700's to the early to mid 1800's and produced some beautiful bottles but the primary business was window glass . There are many reproduction peices out there so careful - most of them are obvious to any one familiar with old glass . As far as distinctive bottle marks try myinsulators.com/glass-factories/bottlemarks3.html .
