For centuries before the invention of the paint tube, artists used to store their paints in pig bladders. When the artist was ready to use the paint, they would puncture a hole in the bladder and squeeze out the desired amount of paint. They would have to mend the hole when finished and the whole process was quite messy.[1] Theoil paint tube was invented in 1841, as the primary packaging of paints for transport and storage.[2]
In thebian lian ("face changing") style of Chinese opera, painted pig bladders were used as face masks.
