Sometimes a tube of paint gets hard, maybe after not using it for months, and you are ready to toss it out. Don’t! It can easily be salvaged and used. Take a single edge razor blade or xacto knive and cut off the ends of the tube. Then slice down the length of the tube to open it up. The dried paint will usually pop out. You can also dig out paint from the cap end that was cut off. Then you can use it either dried, like pan paints; or you can put it all in a small jar (like a prescription pill container or baby food jar), fill it with hot water to barely cover the paint, and put a lid on it. Usually the latter takes about a week for the paint to soften. And voila! No wasted paint.
