European standards demand that to be called “Leaded” Czech crystal it must have at least 24%. High end Czech Crystal production may be labelled as “high leaded” Czech crystal indicating that it has lead content greater than 30%.
The meaning of the word “crystal” varies from country to country. In the Western world, however, crystal is most often called lead glass. We speak of Czech crystal when we say that it is glass produced in the traditional Bohemian region with a lead content of at least 24%.
And the answer is simple: because it's hand-cut crystal, made in the Czech Republic. From molten glass to a polished jewel, each piece is crafted by a skilled artisan who shapes, cools, cuts, and finishes it to perfection. You can't achieve that in 20 seconds with a plastic mold.
The Test: Run your finger over the cuts in the design. Lead Crystal: The edges of the cuts should feel slightly rounded or "soft" to the touch (often polished smooth). Standard Glass: Identifying sharp, brittle, or rough edges usually indicates molded glass or lower-quality cutting.
Lead crystal glassware was formerly used to store and serve drinks, but the health risks of lead have made this use rare. Lead crystal is unsafe to drink or eat from, as the neurotoxic lead leeches out of the glass and into the food.
Reduce your risk of lead exposure
If you use lead crystalware: limit its use to serving food or drinks, never storing. only use it from time to time, such as on special occasions. soak new lead crystalware in vinegar for 24 hours and rinse it thoroughly before use.
“If someone is using lead crystal glass for drinking wine once, that's not going to give a significant amount of lead.” The best practice when approaching vintage glassware is to steer clear from using it on a daily basis, and don't store things in it for a long period of time, Dr. Kosnett recommends.
Chelation therapy.
In this treatment, a medicine given by mouth binds with the lead. The lead then passes out of the body in the urine. Chelation therapy might be needed for children with a blood level of 45 mcg/dL or greater and adults with high blood levels of lead or symptoms of lead poisoning.
Why are you changing from Lead Crystal to Crystal? The decision to remove lead from our production process has been made for environmental reasons and the improved performance of our products.
Soda-lime glass is a practical nontoxic option too. Just beware that soda-lime glass may break more easily but is also less expensive. Again, beware that decorative glass—glass with glazes or enamel, is colored, and lead crystal (or crystal)—may leach toxic chemicals or heavy metals.
Among the most famous Czech glass producers are: Moser (considered the most luxurious Czech brand), Rückl (the glass from them was owned, for example, by the British Queen Elizabeth II), and Crystalex (the largest Czech producer of drinking glasses, own trademark Bohemia Crystal).
To identify Czech glass, first see if your piece bears a foil label or an acid mark that signifies the maker. If you find one, search trusted resources to determine who the maker is and if the company is Czech. Some well-known Czech makers include Moser, Crystalex, Rückl and Škrdlovice.
The Crystal Valley in North Bohemia is definitely the Mecca of Czech glassmaking traditions. However, it is not the only place where glass gems that the whole world admires are made. One of the most famous Czech glassworks can be found in Karlovy Vary.
Common Crystal Combinations to Avoid

It is named after the city of Waterford in Ireland. In January 2009, the main Waterford Crystal manufacturing base on the edge of Waterford was closed due to the insolvency of Waterford Wedgwood plc, and in June 2010, Waterford Crystal relocated almost back to the roots of glass-making in the city centre.
It has no inherent value - it will rather depend on maker/age/scarcity/desirability. There is good and not very good 24% leaded crystal, the best makers make the clearest crystal, mark theirs with their brand name and the others most often do not.
Certain foods can protect against lead poisoning! Vitamin C, calcium, and iron can block lead from being absorbed and may help get rid of it.
Nervous system. The brain is the most sensitive organ to lead exposure (Cleveland et al., 2008). In a child's developing brain, synapse formation is greatly affected in the cerebral cortex by lead.
Signs and symptoms in adults might include:
Despite the recent studies showing that percentages of lead can leak into liquids stored in lead crystal, that does not mean owners have to throw out the crystal stemware they have come to enjoy. Those who may be concerned about even minuscule levels of lead may prefer to buy beautiful glass stemware instead.
Vintage glassware, particularly that made before 1971, may contain lead in the glaze or paint used for decoration, posing a potential health risk if the lead leaches into food.
