40-Year-Old Oil Paint: Does it still work?

You may have some very old paint tubes, perhaps inherited from a relative who used to paint and has stopped, and you wonder if those colors still work. Oil colors last for many years in good condition. It is rare that they expire, but there is no better way than to try them. Let's go to the palette first. When we work, we put the colors on the palette, paint and leave them there for the next day. Normally in 2 or 3 days they do not dry and we can continue using them, but we must always test them first. For example, this color has already created a film on top, like a skin, so what I do is pop it and there is fresh paint inside. This other one is already dry to the touch. It does not stain me. But if I pop it, the color inside remains fresh. Be careful when the oil paint has already been on the palette for a long time. Well, this one is still fresh. But there are some colors that start to dry out or start to feel doughy, no longer runny. It's hard to see through the camera, but you will feel it. Half-dried paint feels thick, like honey. The sign that the paint is fresh is that it flows like butter, but if the paint starts to get too heavy or thick, it is no longer useful. When paint feels this way, it loses its ability to adhere. It is better to always put fresh paint on our palette. If we finish painting and we have a little color left over, we can return it to the tube. Well, this color is not very fresh anymore. It is best to retrieve as much material as possible immediately after working. If the tube is too full we can tap it gently. In this way we lower the paint to be able to return it to the tube. With these old tubes, there is no other way to know than to test them and see if they are still fresh. I have several very old tubes here. You can see how the labels of this brand have changed over the years. This design must be from the 90s, this one from the year 2000 and this one from around 2010. These older ones I imagine are from the 80s . I bought them at a garage sale many years ago. These are colors that I hardly use, which is why they have been with me for many years. These others are still very new. They are both of the same tone. The second, which is newer , feels more fluid. They are at least 10 years apart in their manufacture. But both are still very fresh. Now this other one. Today I was organizing my studio and I found it. As you can see, it is already broken. I squeeze it and the paint comes out everywhere. The tube is rotten. It's broken. And the paint is a little thicker. A common question is: If my color is stiff and dry and I add more oil or turpentine to it and it turns liquid, does it turn fresh again? The answer is no. This color has already started to oxidize and polymerize. It is already in a drying stage. Adding new oil will not restore its ability to adhere. This color still feels a bit fresh. It could still work. The metal in the tube is rotting, but the color inside doesn't feel too thick. I have this other one. It is the same yellow. I press it and the color comes out everywhere. I've never opened these tubes, that's why they are like this. It's breaking. See how it is inside. It is rotten. Look. It is like rubber. Look at the spatula. This no longer works. The other was more fluid. Like this one that comes out of the top. I wouldn't use it anymore, I wouldn't risk it not sticking well to the surface. But this one coming out from the bottom has already started to dry out. Even adding oil to it will not save the color. This! This is oil paint drying. It is very rigid. It no longer flows. You can almost slice it. It no longer works. It feels like caked. This goes to the garbage can. I think it's clear. It no longer flows. This color is too old. It no longer works. Maybe this other one could still be rescued. It still feels fluid. But the problem is that the tube is already broken. I could keep it in a jar. I bought these colors when I was a student 14 years ago and have never used them. So it doesn't make much sense to keep them any longer. This red paint is still fresh. These colors are at least 40 years old and in perfect condition. Only this one that was already drying. And that happened because the tube began to rot, air entered it and it dried up. But these other colors, although they are the same age, are in perfect condition. Of course, the fresher the paint, the better. But if you inherit some colors like these, rest assured that if they flow like butter you can use them without any risk. Hope this video is helpful and see you in the next one.
