Glasco is a hamlet (and census-designated place) in Ulster County, New York, United States.

The glass was carried by horse down the "Glasco Turnpike" to the banks of the Hudson where it was shipped on for ports of sale.

[3] Settled largely by unskilled workers, first from Ireland and then from Italy, they came to the area in great numbers in the late 19th century by ferry after landing in New York City.

At one point, the town boasted over six brick factories, a ferry service, a school, churches and several saloons.

In the bluffs above the clay mining operations of the brickyards, small estates and dairy farms were established.

One family operator, Washburn, allegedly relocated to Virginia to continue brick making.

Recently, residents of New York City have begun to purchase weekend homes within the boundaries of Glasco.

At the foot of the Catskill Mountains, and within walking distance of the Hudson River (relatively unpolluted at that point), the hamlet has seen real estate prices skyrocket since 2000, along with an increase in single-family home construction.
