 Simple coloured tiles or bricks were complemented by relief patterns, and a variety of glazes.However, the fashion for highly modelled surfaces passed and from 1904 the company concentrated on plain tiles used as facing, notably an artificial marble called "Marmo", as used on Atlas House, King Street, Leeds and Michelin House, London, and "Lefco" which had a granite appearance and was also used for garden ornaments.These were in production until the company closed in 1957.
