Inside the black art tube, there are a total of three paintings.
As soon as Gu Weijing touched the inside of the tube with his hand, he frowned immediately.
There's a problem with the preservation method of these paintings—they are rolled inward, and there's no filling in the middle of the tube.
"A very elementary mistake."
A thought immediately crossed Gu Weijing's mind.
Oil painting is a three-dimensional art, the paint isn't merely a simple two-dimensional plane.
It has volume and thickness.
If you've touched the paper of a painting yourself, you'll intuitively feel the surface is uneven like a coarse particle board.
These are marks left by the painter while applying paint with a brush on the canvas.
The paint solidifies layer by layer on the canvas surface, forming the unique gloss and texture of oil paintings.
This paint is relatively fragile.
So after the painting is completed, proper preservation is very important.
