Red Lead Griffin Brand

What is Red Lead non-setting?

Red lead non-setting is a variant of red lead consisting of reactive litharge in very minute quantity. This variant is composed of high quantity of lead peroxide. Red Lead setting or RLNS is available freely in nature in a powdered form.

RLNS finds its uses primarily and widely In the manufacturing of storage batteries and as an oxidizing agent in glass manufacturing process. Red lead non-setting types are also importantly used in creating Waldies Sindur and anti-corrosive paint to cover steel structures. Such types are significantly usd to prevent undue thickening of paints.

Red Lead (Pb304 or 2PbO, PbO2) is soft orange and red colored powder. It is a useful ingredient for the storage battery, glass & ceramic industry and it occupies an important place in the Paint Industry for its rust inhibiting character. It is virtually insoluble in water and alcohol. However, it is soluble in the hydrochloric acid present in the stomach, therefore it is toxic when ingested. It dissolves in hydrochloric acid, glacial acetic acid, and a diluted mixture of nitric acid and hydrogen peroxide.


Red Lead is used to a certain extent in the ceramics and glass, paints and pigments and explosives industries. Waldies Griffin brand Red Lead Non-Setting is a highly superior quality product and is the market leader.

Waldies also produces Red Lead Ordinary conforming to IS :57-1989 Type A and B. This formula corresponds to a PbO2 content significantly lower than 34.0% dependent upon the particular application in which they are to be used.

The material specifications of both Red Lead Ordinary & Red Lead Nonsetting are available in the datasheets attached above.


What is Red Lead Ordinary?

Red Lead Ordinary appears in a vibrant orange to red brick colored pigment which had a chemical property to be able to get dissolved in acetic acid and completely insoluble in water and ethanol. The leading red lead manufacturer in India employs reverberatory furnace to manufacture it by heating lead monoxide at 500°C in the presence of air.

Red lead ordinary has a relatively lower specific gravity, water and acid absorption rate (mg/gm) than red lead setting.  It is mostly used in ballistic modifiers for propellants of high-energy, ceramic glazes, in rubber adhesives and also in foam coatings used in X-rays as a radiation shield.

Industries Served

Casting Industrial Iron Pipelines

Major U.S. cities have 100 percent lead piping bringing water from the utilities to homes and businesses. The dissolved oxygen in the water combines with the metal at the surface (copper, zinc or lead) to form a metal oxide. This oxidation layer naturally develops through the decades to coat lead piping and prevent lead from getting into the water supply. When water conditions require it, water utilities also add lime or orthophosphates as a further barrier to prevent lead from getting into drinking water.

Fittings may be installed by using the tool of your choice or by driving the fitting home by using a lead maul. To do this, strike the fitting on the driving lug or across the full hub. Hit it as hard as necessary, the lead will deform without harming the fitting. Using the lead maul is the fastest and easiest way to install fittings on hub and spigot cast iron soil pipe. Proper safety procedures should be observed in making the joint.

The use of red lead has again drawn the attention of the lead-acid battery manufacturers due to its ability to promote plate formation and deep-cycle performance.

Historically, it was used in pasted and tubular positive plates in order to improve their formation time and enhance deep-cycle performance. Although the use of red lead has diminished over the last few decades, many companies are again considering the use of red lead in their plates.

Frit Glaze Glasses

Lead glass, commonly called “crystal”, is a variety of glass in which lead replaces the calcium content of a typical potash glass. Lead glass contains typically 18–40 weight% 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 glass is desirable owing to its decorative properties.

The high atomic number of lead also raises the density of the material, since lead has a very high atomic weight of 207.2, versus 40.08 for calcium. The density of soda glass is 2.4 g/cm3 (0.087 lb/cu in) or below, while typical lead crystal has a density of around 3.1 g/cm3 and high-lead glass can be over 4.0 g/cm3 or even up to 5.9 g/cm3.

Originally discovered by Englishman George Ravenscroft in 1674, the technique of adding lead oxide (in quantities of between 10 and 30%) improved the appearance of the glass and made it easier to melt using sea-coal as a furnace fuel. This technique also increased the “working period” making the glass easier to manipulate.

As Color Pigments

The traditional method making the pigment was called the stacking process. Hundreds or thousands of earthenware pots containing vinegar and lead were embedded in a layer of either tanbark or cow feces. The pots were designed so that the vinegar and lead were in separate compartments, but the lead was in contact with the vapor of the vinegar. The lead was usually coiled into a spiral, and placed on a ledge inside the pot. The

The lead was usually coiled into a spiral, and placed on a ledge inside the pot. The pot was loosely covered with a grid of lead, which allowed the carbon dioxide formed by the fermentation of the tanbark or the dung to circulate in the pot. Each layer of pots was covered by a new layer of tan, then another layer of pots. the heat created by the fermentation, acetic acid vapor and carbon dioxide within the stack did their work, and within a month the lead coils were covered with a crust of white lead.

This crust was separated from the lead, washed and ground for pigment. This was an extremely dangerous process for the workmen. Medieval texts warned of the danger of “apoplexy, epilepsy, and paralysis” from working with lead white.

Manufacturing of Detonators

Due to the properties of the chemical element of Lead. The manufacturers of Detonators use Lead Oxides to achieve the maximum level of the explosion.
