Do you have a collection of dried up paint tubes you just can’t bring yourself to throwing out?
Here is a way to bring the paint back to life. I found a small pestle and mortar hidden in the back of a kitchen cupboard. It turned out to be the perfect device for grinding the contents of all those dried out tubes into a fine powder, ready to be brought back to life.
The first thing to do is cut open the tube and empty the dry lumps of pigment into the motar
Next step is to grind them to a fine powder. The pigment sticks to the pestle, so a metal palette knife is handy to scrape and loosen the pigment.
Once the pigment is a fine even powder, slowly stir in some water. Just enough to make a thick, creamy consistency. Keep grinding the paste for a few minutes to make sure there are no small, unbroken lumps left.
The final step is to scoop the recycled paint into a container. These little plastic sauce containers come from the local Thai restaurant – a couple of dollars for a plastic bag full. A piece of masking tape with details identifying the brand and color is a good idea before you throw away the empty tube.
Some pigments contain heavy metals such as Cobalt and Cadmium (check the warnings on the tube). Be careful not to breathe in or swallow the dust off these. Wear a suitable mask if in doubt.
