William Wilson's other son, George had become company chemist and, with his assistant George Gwynne, was responsible for many of these new chemical processes. The company acquired a reputation for innovation and it generally had first refusal to work any newly patented inventions. As well as industrial chemistry there was the development of mass production processes. In 1849 they installed a system that moved candle moulds round the factory on a railway. By 1864 a new method of ejecting candle from moulds using compressed air pushed candle production to 14 tons a day. A decade later increased mechanisation enabled "Price's Patent Candle" to produce 32 million nightlights a year and dominate that market.
