In what period was glass first manufactured in America?

Glass manufacturing in America began to gain traction in the late 1700s. This period marked significant advancements in the technology and processes involved in glassmaking. Although there were earlier attempts and small-scale production, the establishment of more systematic glass manufacturing operations occurred during this time. The first successful glassworks in America, known as the "New Jersey Glass Works," was founded in 1739, but it was the late 18th century that saw a more widespread development and commercial viability of glass production.

Further evolution in techniques and increasing demands for glass products contributed to the growth of this industry, leading to a more recognizable presence of manufactured glass throughout the country. The options indicating earlier or later timeframes do not align with the historical context surrounding the establishment and proliferation of glass production in America.
