In Glasgow, Dale’s business profile continued to grow. In Dalmarnock he set up a dyeworks where cloth was dyed with a new, colourfast dye called ‘Turkey Red’ (sometimes known in the city as 'Dale’s Red’). In the centre of town, in what is now Ingram Street, he built a warehouse and small manufactory which produced linen strips or tapes known as ‘incles’ or Scotch Tape. The company traded under the name Dale, Campbell, Reid & Dale. The second Dale here is David Dale’s nephew, also David, and known as David Dale Junior. Still in Glasgow, Dale invested a significant sum in the insurance business. He became a Director of the Glasgow Fire Insurance Company. Despite its name, the company sold life insurance and annuities and had offices in George Street and Wilson Street. Dale also owned a significant amount of land and property in and around the city. Records show at least 18 land and property transactions in his name. These included lands and tenements in the Ramshorn (Ingram Street) area, tenements in Shuttle Street, properties in Barrowfield and Ruchill and a major investment in land and property in the Parkhead area.
