The vast majority of sugar houses, big or small, early or late, refined raw sugar in order to produce sugar for sale in the forms of loaves, lumps, ground, granulated, cubes, etc, as well as dark treacles and golden syrups, and of course molasses. There were just a few however, 1790s to 1890s, that concentrated on the production of capillaire and spirit colour, both light syrups, but for very different purposes. These refiners often styled themselves as "Liquid Refined Sugar Makers".

Capillaire was a water-clear syrup originally flavoured with dried maidenhair fern though later with orange-flower water, much used by confectioners as a flavouring, and also as a cordial. (1) In the theatre advertisements on the front of The Times the sale of capillaire as a refreshment was often mentioned.
(For an idea of the liquid refined sugars produced today, take a look at the Sugar Australia website.)

Spirit colour was developed as a colouring for rum ... a boiled dark muscovado sugar with a small amount of rum added was produced, and about 3 pints would colour 100 gallons of spirit. (2)
(The website regarding Caramel Colors gives us an insight into how this trade has developed more recently with our greater 'need' for food and drink colourings.)
