Shimmering glass was manufactured here more than a century ago, and the the Sandwich Glass Museum shows you what the factory looked in its heyday. There's an "ingredient room" showcasing a wide spectrum of glass colors along with the minerals added to the sand to obtain them, and an outstanding collection of blown and pressed glass in many shapes and hues. Large lamps, vases, and pitchers are impressive, as are the hundreds of candlesticks on display. There are daily glassblowing demonstrations between 10 and 3. The extensive gift shop sells some handsome reproductions, including some made by local and national artisans. The museum also hosts historic walking tours on certain days from June through October.
