- Cerussite (Natural Lead White) 1  Cerussite is natural lead carbonate, and is close in composition to lead white. Our cerussite comes from the deposit in Kazakhstan. 2  Availability: Usually ships in 24 hours. 3  Alternate Names: lead white, white lead, flake white, and Cremnintz white are names given to synthetic lead carbonate pigment. Cerussite is natural lead carbonate, and is close in composition to lead white or flake white. The name of the mineral comes from Latin cerussa for whiting.

Lead (II) sulfate Lead(II) sulfate (PbSO 4) is a colourless solid, which appears white in microcrystalline form. It is also known as fast white, milk white, sulfuric acid lead salt or anglesite.ead(II) sulfate can be dissolved in concentrated HNO 3, HCl, H 2 SO 4 producing acidic salts or complex compounds, and in concentrated alkali giving soluble hexahydroxidoplumbate(II) [Pb(OH) 6 ] 2− complexes.

White lead White lead, any of several white pigments used in exterior paints and containing inorganic compounds of lead. lead (Pb) a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. Lead is very malleable, ductile, and dense and is a poor conductor of electricity.

Colander A colander is a bowl-shaped kitchen utensil with holes in it used for draining food such as pasta or rice. The perforated nature of the colander allows liquid to drain through while retaining the solids inside. It is sometimes also called a pasta strainer or kitchen sieve. Conventionally, colanders are made of a light metal, such as aluminium or thinly rolled stainless steel. Colanders are also made of plastic, silicone, ceramic, and enamelware.

lead In its metallic form, lead is used as a protective shielding against x-rays. Lead is poisonous, a characteristic that has led to a reduction in the use of lead compounds as pigments for paints and inks.In dentistry, lead acts as a protective shield against the radiographic beam and is found in the lead apron and walls of the surrounding operatory.) It is poisonous, a characteristic that has led to a reduction in the use of lead compound as pigments for paints and inks. lead apron, n See apron, lead.

Lead (II) chloride Lead(II) chloride (PbCl 2) is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water.Lead(II) chloride is one of the most important lead-based reagents. It also occurs naturally in the form of the mineral cotunnite.n solid PbCl 2, each lead ion is coordinated by 9 chloride ions – 6 lie at the apices of a trigonal prism and 3 lie beyond the centers of each prism face. The 9 chloride ions are not equidistant from the central lead atom, 7 lie at 280–309 pm and 2 at 370 pm. PbCl 2 forms white orthorhombic needles.

Lead Salts Lead dioxide is in the +4 state. Not usually too easy to get to; you can reach a half-and-half compromize (red lead) pyrolytically, well somehow anyway. I've roasted pure lead hydroxide to an orange to pinkish red color before, but never a pure Pb3O4 state, and never starting from just lead metal.

Why does Red+Green+Blue paint make black, but those colors of light make white? If you've ever noticed, the main colors used to create white light are Red, Blue, and Green (technically, red, orange, yellow, green, blue, indigo, violet), such as on a projector, you will notice they have these three color lamps. That is pure light, and mixing all pure light colors gives white light. Colors that we see on objects, however, are based on what is reflected back from the objects themselves. The primary pigment colors are not Red, Blue, Green typically, but Yellow, Cyan, and Magenta.

Lead poisoning Lead poisoning (also known as plumbism, colica pictorum, saturnism, Devon colic, or painter's colic) is a type of metal poisoning and a medical condition in humans and other vertebrates caused by increased levels of the heavy metal lead in the body.he Centers for Disease Control (US) has set the standard elevated blood lead level for adults to be 10 µg/dl of the whole blood. For children the number is set much lower at 5 µg/dl of blood as of 2012 down from a previous 10 µg/dl. Children are especially prone to the health effects of lead.

- Molten lead color. Hi all-I was doing some casting this weekend and noticed that I couldn't quite keep the color of the molten lead a shiney silver color (like quicksilver / mercury).Instead, it was more of a gold color, with a thin skin on the top.old is a good indicator of tin. pure lead will usually show a blue/purple color. put a heat barrier on top of your mix it will also help keep the oxides down and the temp more consistant. it's all an educated guess,,,, till the trigger is pulled.

What's with China and lead poisoning? First, lead paint is inexpensive, and it produces vivid colors. It also goes on easily and resists corrosion. In the United States, lead paint was outlawed in 1962 for use in children's toys and products, apartments, houses, hospitals and similar structures.

- Common Lead-Based Paint Terms. 1  Lead-Based Paint: Any paint, varnish, shellac, or other coating that contains lead equal to or greater than 1.0 mg/cm as measured by XRF or laboratory analysis, or 0.5 percent by dry weight (5,000 mg/g, 5,000 ppm, or 5,000 mg/kg) as measured by laboratory analysis.

Why use lead in paint? Any paint that relies on lead compounds for its colour. White lead, or lead(II) carbonate (PbCO3), is a typical example, and was once widely used to paint wooden surfaces in homes. Other lead compounds, like vivid yellow lead chromate (PbCrO4), were used as coloured pigments.

- Lead is a bright and silvery metal with a very slight shade of blue in a dry atmosphere. On contact with air, it begins to tarnish by forming a complex mixture of compounds depending on the conditions. The color of the compounds can vary.ead-205 is the most stable radioisotope of lead, with a half-life of over 10 7 years. 47 nuclear isomers (long-lived excited nuclear states), corresponding to 24 lead isotopes, have been characterized. The most long-lived isomer is lead-204m2 (half-life of about 1.1 hours).

- There is actually no such thing as a “white” LED. To get white light, the kind we use for lighting our homes and offices, different color LEDs are mixed or covered with a phosphor material that converts the color of the light. The phosphor is the yellow material you can see on some LED products.

The Unleaded Pencil • Charcoal pencils, used primarily by artists, are another popular form of black lead pencil, made from a different form of carbon than graphite that is more like coal. These make a very dark black mark on the paper compared to even very soft graphite pencils, such as 8B.

General Chemistry/Chemistries of Various Elements/Transition Metals Transition metals and their oxides, when dissolved, form colored compounds. Group 1 and 2 metals are clear when dissolved and white when precipitated. Other metals, like lead, are clear when dissolved and may have color when precipitated (lead precipitates are yellow).
