Powdered pearl has a long history of use in face and body powders. Pearls are usually white or bluish-grey in colour, with a fine lustre and, being expensive to own, highly sort after. Chemically, they are made up of layers of aragonite (a form of calcium carbonate) held together by the protein conchiolin. This substance forms a soft, fine, white powder when ground.
The practice of powdering pearls for use in cosmetics may have started in China where it continues to this day. The pearl used was most likely garnered from fresh-water species of oysters rather than the more expensive salt-water varieties. There were also cheaper versions that used the mother-of-pearl from the nacreous internal lining of oyster shells. After being made in the East, the powders made their way to Europe to become one of many exotic materials found in well stocked apothecaries to be sold separately or in cosmetic kits.
Pearl Powder. Of these powders there are several sorts; the first and finest is a magistery made from real pearls, and is the least hurtful to the skin. It gives the most beautiful appearance, but is usually too dear for common sale or use: still the good perfumer ought never to be without it, for the use of the curious and the rich.
Imitated by other kinds of powder, some of which are made from mother of pearl, and some from oyster-shells; but, as the magistery made from these is never so impalpably fine as the former, they leave a shining appearance on the face, which shows the art that has been used on the very first view.
Chinese boxes of colours
These boxes, which are beautifully painted and japanned, come from China. They contain each two dozen of papers, and in each paper are three smaller ones, viz. a small black paper for the eyebrows; a paper, of the same size, of a fine green colour, but which, when just arrived and fresh, makes a very fine red for the face; and lastly, a paper containing about half an ounce of white powder (prepared from real pearl) for giving an alabaster colour to some parts of the face and neck.
The use of pearl was not confined to face and body powder. Like many other gems, they were considered to have health benefits; for example, it was one of many exotic ingredients used in the eighteenth-century to make a cold nostrum referred to as Gascoign’s powder. Even today, many health benefits are ascribed to it. When taken orally, it is said to have ‘anti-ageing properties’ and when applied to the skin it is believed to be able to “tone and rejuvenate complexion, heal blemishes, minimize large pores and reduce redness”. Although attempts have been made to find health benefits in conchiolin, none of these claims have been scientifically verified.
In the nineteenth-century, the use of imported powdered pearl was a luxury only afforded by a few. However, this did not stop the manufacturers of face powder invoking its name. Pearls are a symbol of whiteness, purity and costliness, which is perhaps why the entrance to Heaven was said to be through Pearly Gates. By associating their powders with pearls, the manufacturers hinted that they had all these qualities, even when they were made of more inexpensive materials.

There were however, only a few powders that could mimic the softness and whiteness of real pearl and live up to it in more than their name. The most important of these were the ‘bismuth-whites’.
Known for their soft skin feel and adhesive properties, these were either bismuth oxychloride (referred to as base chloride or subchloride in the literature of the day) or bismuth subnitrate – bismuth oxychloride had a pearly sheen, while bismuth subnitrate had the advantage of being more astringent. When mixed together with other materials they went by names such as pearl powder, pearl white, bismuthine cream, blanc de perles, and fard blanc de bismuth.

Given that lead pigments in powders had been shown to be harmful to health, some nineteenth-century writers cautioned against the use of bismuth-whites in cosmetics as well.
The continued use of ‘bismuth-whites’ injures the skin, and ultimately produces paralysis of the minute vessels, rendering it yellow and leather-like – an effect which, unfortunately, those who employ it generally attempt to conceal by its freer and more frequent application.
Pearl-white is far more dangerous than rouge, as it is made of bismuth. Its use is most injurious to the skin, rendering it yellow and leather-like, and inducing paralysis if long continued.
Some of this animosity may haver been generated by the fact that these powders were sometimes associated with the practice of enameling.

Fortunately, not all nineteenth-century writers agreed that the use of bismuth was a problem.
Some physicians have decried this metal in both these forms as injurious to the skin and unsafe to the general health. There is doubt about this opinion. We have given it for months, both internally and externally, without any ill results, and do not feel convinced that it is more objectionable on the score of health than French chalk.
However, despite these more positive reports, the negative feelings associated with bismuth persisted. At the turn of the century, for example, Helena Rubinstein deemed it necessary to state that no lead or bismuth was used in her powders.

The bismuth whites proved to be safe and went on to be widely used in the twentieth-century. Bismuth subnitrate – with its astringent properties – was used cosmetically in bleaching, freckle creams and hair dyes while bismuth oxychloride was incorporated into lipsticks, eyeshadows, and other cosmetics as a filler or synthetic pearl.
As well as doubts about their safety, bismuth-whites had another widely known drawback. Some forms tended to go grey when they came into contact with the sulphurous gas produced from coal fires or coal gas lighting.
It [bismuth] has, indeed, in common with all the metallic substances used for this purpose, one serious drawback. They are all changed by sulphurous gases into dark gray sulphurets, and as luck will have it, our coal fires and gas-pipes are constantly ready, whenever opportunity is allowed them to fill the apartment with just such gases. The consequence is that on not a few occasions, ladies, who at the outset of the evening displayed complexions which made their rivals ready to tear their hair with envy, have come to grief in the most unexpected manner, and been obliged to retire in confusion, with their faces of a dirty ash color, owing to some stupid servant mismanaging the furnace and allowing the gas to escape.
The use of bismuth compounds in face powders declined somewhat when zinc oxide was introduced. Henry Tetlow was one of its early adherents and incorporated it into his very successful Swan Down Face Powder, made in the United States from 1866 onwards. Titanium dioxide was also increasingly used as a white pigment. It was a more brilliant white than zinc oxide and today is found in a wide variety of cosmetics.
As the twentieth century progress cosmetic chemists became more interested in replicating the lustrous effects of pearls rather than their whiteness. Pearliness in the form of pearl essence – a product developed from fish scales – was first introduced into nail polish but other cosmetics soon followed. However, it was not until after the Second World War that ways were found to introduce the effect into powders.
