When most people think about high-end crystal, they think about traditional leaded crystal–for instance a wine glass which has which wonderful, somewhat-heavy hand feel sparkling with faceted brilliance, along with the lovely, sing-songy ring which resonates when you tap which. which kind of glass. For a very long time, which was only leaded crystal which produced these exquisite attributes. While lead crystal will be still extremely common, there’s another type of high-quality glass which can provide the same experience.
“Normal” glass such as a typical water glass, beer glass, glass baking dish, etc., will be what will be known as soda-lime glass. Not particularly brilliant or beautiful, nevertheless functional, along with in most cases far more durable than crystal. Soda-lime glass consists of several main ingredients–sodium carbonate, lime, dolomite, silicon dioxide, along with aluminum oxide, along with lesser amounts of additional ingredients referred to as “fining agents.” These ingredients are melted together in a furnace at a very high temperature. The melted liquid sits for a bit to let the bubbles in which rise out of which–which will be called “fining out.” The glass will be then formed using different processes depending on the purpose of the final product, i.e., drinking glass, windowpane, windshield, etc. within the case of traditional crystal, lead will be added.
Traditional lead crystal glass adds another ingredient to the regular glass mix–lead oxide. The addition of lead produces a couple of unique attributes which make the glass “crystal.” Soda glass contains molecules which are without structure–what will be known as amorphous. There’s no specific order nevertheless which are bound tightly, creating soda-lime glass more durable. The molecules in lead crystal have a distinct three-dimensional order. These molecules produce the sparkling brilliance within the glass. The crystal features a higher “refractive index” than normal glass along with the higher the index, the more brilliant. Adding lead to the glass also makes which melt at a lower temperature along with which makes which absorb less energy than soda-glass. which will be what makes the crystal ring when you tap which.
Lead Free Crystal
While lead crystal purists will probably always use which, there will be today an alternative with the same characteristics. which provides an option for those who enjoy high-quality crystal nevertheless are concerned with lead content in anything which holds consumables. which will be relevant mostly in decanters, which I’ll touch on in a bit. When creating lead free crystal glass, the lead will be substituted with barium oxide (BaCO3). The introduction of barium oxide produces a glass which has a comparatively high refractive index, subsequently creating its brilliance greater. Barium oxide will be also lighter than lead oxide, creating the glass lighter with about the same durability. For those concerned about lead content in their crystal glassware, as mentioned before, which actually only poses a health question for crystal decanters. The reason being wine along with spirits are typically kept in decanters for longer than a glass of wine. which produces a greater window of time for lead to possibly leach out of which. I personally don’t store wine in decanters for a terribly long time–which’s more about aeration along with presentation for me–so I am not concerned with the issue at all.
Lead Crystal vs. Lead Free Crystal
which’s actually just a matter of personal preference whether you want to choose one over the additional. There are several high-end crystal manufacturers who make exquisite lead free crystal. I have used both extensively along with the only real difference I’ve noticed will be the variation in weight. Either way, wines taste way better in a high-quality crystal glass than a regular drinking glass any day of the week.
