PPG expanded quickly. By 1900, known as the "Glass Trust", it included 10 plants, had a 65 percent share of the U.S. plate glass market, and had become the nation's second largest producer of paint. [4] Today, known as PPG Industries, the company is a multibillion-dollar, Fortune 500 corporation with 150 manufacturing locations around the world.
Super-LumiNova is a brand name under which strontium aluminate–based non-radioactive and nontoxic photoluminescent or afterglow pigments for illuminating markings on watch dials, hands and bezels, etc. in the dark are marketed.
Photoluminescence (abbreviated as PL) is light emission from any form of matter after the absorption of photons (electromagnetic radiation). [1] It is one of many forms of luminescence (light emission) and is initiated by photoexcitation (i.e. photons that excite electrons to a higher energy level in an atom), hence the prefix photo- .

The District of Columbia defines "lead-based paint" as any "paint, surface coating that contains lead equal to or exceeding 0.7 milligram per square centimeter (0.7 mg/cm2) or 0.5% by weight." [9] This is more stringent than the HUD lead-based paint standard of 1.0 mg/cm2) . Some states have adopted this or similar definitions of "lead-based ...
Most photoluminescent events, in which a chemical substrate absorbs and then re-emits a photon of light, are fast, in the order of 10 nanoseconds. Light is absorbed and emitted at these fast time scales in cases where the energy of the photons involved matches the available energy states and allowed transitions of the substrate.
