Furniss went on to expand his company to Furniss Foods, a well-known Cornish biscuit manufacturer, which created a number of different fairing varieties, such as "orange and lemon" or "apple and cinnamon". He also established a Charitable Trust which is still in operation today. It is limited to the parish of Truro to provide assistance to residents in need who use coal as the primary source of heat. The company moved to a larger factory in 1988, but ran into financial difficulties during the 2000s and it was bought by Proper Cornish, a pasty manufacturer, which focused the company's production on the Cornish fairings and a couple of other lines.
