How to rescue tubes of solidified watercolour

If colour has solidified in your watercolour tube, it is not possible to return it to its liquid form. But it can be used as a type of pan colour. Simply add a little Winsor & Newton Gum Arabic medium to water and then use the dried tubes as pans.

Although they won’t perform as well as our Artists’ Water Colour formulated specifically for pan application, this trick does mean you can continue to use old solidified tubes.

To prolong the life of watercolour tubes as long as possible, try to ensure:

  1. The threads on the neck of the tube are free of colour
  2. The lids are replaced tightly
  3. The tubes are stored at ambient temperature
