Factory founded in Stoke-on-Trent in 1793 by Thomas Minton (1765-1836), who was succeeded on his death by his son, Herbert Minton (1793-1858). The factory traded under various names until 1845 when Minton & Co. was adopted. In 1868, the firm split into two divisions, one for tiles only, the other for china (though it also made tiles). In 1845, the tile business became a separate department, trading as Minton & Co for encaustic or inlaid tiles which were mostly floor tiles, and as Minton, Hollins & Co for printed or painted or majolica wall tiles. After Herbert Minton's death in 1858, the tile business was continued by Michael Daintry Hollins, who had become a partner in 1845, while the china business was continued by Colin Minton Campbell, who had become a partner in 1849. Hollins and Campbell carried on in partnership until 1868, when they split up, Hollins carrying on the tile business, and Campbell the china works, trading as Minton's China Works, which also produced tiles (though not encaustic tiles) until 1918. In 1869, Robert Minton Taylor set up a new tile factory, trading as Robert Minton Taylor, until he was bought out by Campbell in 1875 as the Campbell Brick & Tile Co. Both the Campbell Tile Co and Minton, Hollins & Co were absorbed by H & R Johnson-Richards in the 1960s.
