The molded glass is then transferred to a machine that reheats and stretches the neck to create the stem. Machine-blown wine glasses are produced by pouring molten glass into molds in a revolving machine that uses compressed air to create the wine glass bowl and neck. “Today we’re able to enjoy high-end machine-made glass that appears to be hand-blown, which is very impressive,” says Cabrales. Today’s best machine-made wine glasses use innovative techniques that simulate traditional glassblowing to mimic the look and feel of handblown glassware. Historically, machine-made glasses were heavy and dull, but glass-making technology has improved drastically over the years. The Modern Marvel and Appeal of Machine-Made Wine Glasses The use of crystal decanters with lead is not recommended, however, because over time, leaching will occur, releasing the lead from the glass into the wine. The dangers of lead exposure are hotly debated, but it’s believed that glasses pose very little risk. A crystal glass can have a bell-like chime and is more sparkly than glass, but it tends to be porous, so handwashing is usually recommended.Ī word about lead: Traditionally, all crystal glass was made with lead and some still is. Crystal, on the other hand, is more delicate, and can be more easily spun into thinner walls and rims. Glass, such as borosilicate and soda-lime, is typically thicker, and inherently stronger l than crystal. More commonly used for today’s finest wine glasses, lead-free crystal glass is a lighter form of crystal glass, offering the similar brilliance and clarity of leaded crystal without the weight or health hazards. Crystal glass is known for its brilliant refractive qualities and contains strengthening minerals like lead-oxide, potassium carbonate or barium oxide to make the material more durable. Before we get into production methods, it helps to understand the difference between glass and crystal.
