hey specialised in experimental decorative glaze effects. Lustres, flambe and crystalline effects were produced, some being very similar in to William Howsen Taylor's Ruskin Wares.
He is known to have exhibited at the International Exhibition Brussels 1910 (gold medal for Vasco and adventurine) , Arts and Crafts Exhibitions 1912 & 1916, the Turin International Exhibition 1911, Ghent Exhibition 1913 and British Industrial Arts Exhibition 1920.
Production was temporarily suspended during the first World War and by 1922 the pottery had merged with William Ault's pottery to form Ault & Tunnicliff then Aultcliff and finally just Ault Potteries Ltd by 1937.
After production ended Pascoe worked as a water engineer and moved to Hartshorne. He died in 1956 aged 75.
