Price's candles were originally made from coconut oil and tallow; they were cheap, and burnt brightly and clearly. In the 1840s the firm expanded and took over Samuel Child’s night-light works at Brompton. The night-light manufacture was moved to Vauxhall; the factory was enormous. Another night-light factory (Albert’s) at Belmont was taken over by Price’s, and moved to new premises under the arches of the South Western Railway.
By the early 1850s, Price’s switched to making candles from palm oil, which were marketed as an ‘ethical’ product. Palm oil exports were more profitable for African producers than slavery, which still thrived even though it was banned in Britain and the colonies since 1834.
The palm oil ships unloading their freight at Vauxhall were known locally as the ‘African Blockading Squadron’. Every Price’s candle burnt was said to ‘put out a slave’ (Fraser’s Magazine, July 1852).
The candle factory would find it difficult to market itself as an ‘ethical’ concern nowadays because of its heavy reliance on child labour. The children often worked nights from six p.m. until six a.m. The ‘patent’ candles were made by huge machines which processed the fat into giant ‘cakes’. The cakes were melted in vats, and the liquid poured into moulds (unlike traditional candles made by repeated dipping a wick in tallow or wax). Boys helped move the cakes of fat to the vats ready for melting. Children packed the candles in boxes.
When the firm took over Child’s night-light factory it acquired more child workers (children’s nimble fingers were well-suited to making night-lights) A writer who visited the factory thought the production line, with its ‘little army of boys in clean blouses and caps’ and ‘long rows of girls in pinafores’ looked like a school-room.
Boys punched out cardboard and tin components to make ‘cups’ to hold the fat in the night-lights. Some fixed the wicks in the lights, and others filled the cups with the fat or ‘stearine.’ Girls plaited cotton wicks for the night-lights.
James P. Wilson, managing director of Price’s Patent Candle Factory, was deeply religious, and wanted to look after his young workers’ health and morals. In 1848 Wilson set up schools at his own expense for his child factory workers. Wilson's factory schools became famous, and he was swamped by letters of congratulation from well-wishers including factory inspector Robert Baker and writers Harriet Beecher Stowe and Mrs Gaskell.
