Cut glass wine glass made of lead glass. Lead glass, commonly called crystal, is a variety of glass in which lead replaces the calcium content of a typical potash glass. [1] Lead glass contains typically 18–40% (by mass) lead(II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO.

Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. [2] Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, numbness and tingling in the hands and feet. [1]
Lead glass Lead yellow and lead red. In addition to being the main application for lead metal, lead–acid batteries are also the main consumer of lead compounds. The energy storage/release reaction used in these devices involves lead sulfate and lead dioxide: Pb (s) + PbO 2 (s) + 2 H 2 SO 4 (aq) → 2 PbSO 4 (s) + 2 H 2 O (l)
2 Pb(NO 3) 2 → 2 PbO + 4 NO 2 + O 2 PbCO 3 → PbO + CO 2. PbO is produced on a large scale as an intermediate product in refining raw lead ores into metallic lead. The usual lead ore is galena (lead(II) sulfide). At a temperature of around 1,000 °C (1,800 °F) in air, the sulfide converted to the oxide: [4] 2 PbS + 2 O 2 → 2 PbO + 2 SO 2
Stiegel's works was the first to make lead glass in America. [50] The lead glass of this time period, commonly known as crystal because it was colorless and transparent, was typically used for fine tableware. [51] According to the American Philosophical Society, Stiegel's lead glass was "equal in beauty and quality to the generality of Flint ...
The World Health Organization (WHO) specifically notes that there is "no known safe blood lead concentration," and that even blood lead concentrations as low as 3.5 µg/dL (micrograms per ...
Leaded glass may refer to: Lead glass , potassium silicate glass which has been impregnated with a small amount of lead oxide in its fabrication Lead came glasswork , glass panels made by combining multiple small pieces of glass, which may be stained, textured or beveled, with cames or copper foil
One recent study found that a moderate increase in a kid’s blood lead level corresponds with a 5% higher likelihood of committing a crime, and another one found exposures to lead place boys at ...
