Making — Recycling watercolour tubes into pans
Reformulating tube watercolours
Reformulated paints drying in palettes

My lovely wife, Alison West, had some watercolour tubes that she wanted to use in her classroom but she did not like how wasteful students could be with the paint.

They would typically squeeze out a large amount of watercolour from the tube each day, and then mess it up or leave it to dry as a flaky mess. Students would share palettes, but this led to palettes not being maintained.

Sometimes students would ruin the palettes by using them to mix acrylic.
