Getting the most out of a tube of watercolour paint

A half pan full of water and a little bit of green pigment, in front of a cut open tube of watercolour paint.

I’ve read that buying watercolour paint in tubes is more economical than buying pans. You can fill a pan multiple times from one tube! they say. Whoever they are.

Well. I have this 5ml tube of Daniel Smith’s Viridian that barely filled a full pan. Tbh I was pretty disappointed as it wasn’t cheap at ~$13.50. And it shrank so much that it made me rethink my entire choice on buying tubes of paint.

Anyway, in the interest of getting the most out of this tube after squeezing out what I could, I cut it open with a Stanley knife to see if there was anything left inside. There was a little bit. Maybe not worth salvaging but I gave it a go anyway.

I used a toothpick to scrape what was left of the paint out into an empty half pan, then a wet brush to wash the last of the paint into the pan.

There’s a lot of water, so once it evaporates we can see how much paint is left...

Final result

Here’s what I was able to salvage from that ’empty’ tube of viridian paint, now that all the water has evaporated. The saddest little rectangle of paint ever, but it's more than nothing!
