Starch in their eyes: Brown & Polson

Brown & Polson introduced corn flour to Britain.

John Polson (1800 – 1843), William Polson (1810 – 1893) and John Brown (1806 -1889) merged their starch manufacturing interests in 1842 to form Brown & Polson with a factory at Thrushcraigs, Paisley.

Brown & Polson had been appointed starch manufacturer to Queen Victoria by 1853.

John Polson Jr (1825 – 1900) discovered a method for manufacturing pure starch from maize, which he called corn flour. He patented the process in 1854. It was the first corn flour to be manufactured in Britain.


Corn flour was a thickening agent for foods, advertised as a substitute for arrowroot, and used to make custard, blancmange, puddings and cakes.

The Thurscraig works were sold off in 1857, and production was relocated to the Royal Starch Works at Carriagehill, Paisley.

William Polson left the partnership in 1857 to enter into starch manufacture for himself.

The influential Dr Hassall confirmed the purity of Brown & Polson corn flour in 1858. This represented a major promotional coup for the firm.

Brown & Polson employed 32 men and 60 women by 1861.

A factory fire caused damage estimated at £40,000 to £50,000 in 1866. Two boys lost their lives by venturing too close to the burning building.

Brown & Polson employed around 200 people in 1871. The firm introduced a profit sharing scheme for its workforce from 1873.

In 1879 the partners were John Polson Jr, John Brown and John Armour Brown (1839 – 1924).

John Polson Jr was a practical and thrifty man, as well as a generous benefactor.

Brown & Polson employed 277 people in 1881, including 89 men, 14 women, 86 boys and 88 girls.

Brown & Polson converted the by-product of corn flour manufacture into animal feed, which by 1884 had become a significant part of the business in its own right.

Brown & Polson was considered an enlightened employer. The firm was proud to announce in 1893 that a worker had never encountered the loss of a life or a limb in their factories, and the workforce had never gone on strike.

  1. I’m directly descended from William Brown of Brown & Polson, through my late paternal grandfather, Dr. John Brown MBE of Bedlington, Northumberland. Family legend has it that his father had some sort of dispute with the family and moved to the North East to start a new life on his own without the support of the family. When I was a child, my father took me to visit some of my relatives from that side of the family in Dumfries, but that is the only contact that I have ever had. If anyone knows anything about the Browns of Brown and Polson and the other descendants, I would love to know for the purposes of my own family research. You can find information on my late grandfather here:

    Kind regards,

    Ian Brown

  2. members of my family all worked at the starch works from Thrushcraigs to Falside road from the 1850’s

    I have a photo of my great grandfathers retirement from Brown and Polson’s. and a large Children’s Christmas Party

    My great grandfather and then my grandfather rented a works house in Falside road. My father grew up at 99 and in in the 90’s my brother met and married a woman he worked with in CPC and they moved into a Brown and Polson’s house then owned by the local authority, they now own it.

    I would like to know if you can say where all the Archives for Brown and Polson’s finish up.
