Wine glass materials

Gepubliceerd op 2 december 2020 om 15:06

Wine glasses can be made of many different materials. While glass and crystal are the most common, alternate materials like acrylic and silicone are also used.

1. Soda-lime glass
Most glasses are of the soda-lime variety. It’s the same type of glass you’ll find on your window panes or food jars.

When used for wine glasses, it has the advantage of being more affordable than crystal. It’s inert and nonporous, meaning it won’t absorb chemical aromas, so it’s always dishwasher safe. That said, soda-lime wine glasses will tend to be thicker than crystal stemware and are more durable. handmade vintage art casted wine glasses

2. Crystal
Crystal wine glasses contain 2-30% of added minerals, which is its primary difference from regular glasses. Those minerals could be lead, magnesium, or zinc, allowing the crystal to be spun much thinner than glass but still retain structural strength.

Crystal glassware also refracts light better, making your wine look sparkly in the glass.

However, the addition of minerals to the crystal makes it porous and not always dishwasher safe.

You also have the option of leaded vs. lead-free crystal stemware:

A. Leaded crystal
Historically, all crystal glasses had lead added, and many still do. Leaded crystal wine glasses are safe, as your wine won’t stay long enough in the glass for the lead to leach into it.

But some glass manufacturers have moved to lead-free crystal because of the potential health concerns (like storing liquor in a leaded decanter for a longer period).

B. Lead-free crystal
Lead-free crystal glasses typically have magnesium or zinc additions and are usually dishwasher safe.

Manufacturers like Schott Zwiesel have gone a step further, patenting a crystal called Tritan®, which has infused titanium and zirconium. This makes a highly break-resistant lead-free glass.

Note: Tritan® shouldn’t be confused with Eastman’s TritanTM. TritanTM is a type of plastic also used to manufacture wine glasses.

3. Alternative materials
Other materials commonly used for lower-end wine drinking glasses would be acrylics, metals like stainless steel and silicone.
