Material identification of daily oil canvas

　　　Generally, the canvas does not need to be bleached and dyed, which will seriously damage its strength and durability.

　　Flax has high strength, low elongation, corrosion resistance, mildew resistance, dirt resistance, and quick moisture dissipation. Linen fabrics are dimensionally stable and durable, and are traditional excellent canvas substrates. According to different methods of making hemp fibers, there are bright yellow warm water hemp (soaked in water) and blue-gray rain dew hemp (field wind, rain and frost dew hemp).

The flax seedlings are harvested and rolled into bundles and placed in the field. After rain, dew, wind and frost, the central wood of the hemp rod is decayed, pressed and combed to obtain bast fiber in the blue-gray cortex.

　　Linen cloth is dimensionally stable, extremely strong, moisture-resistant, corrosion-resistant, mildew-resistant, not brittle, and durable, with very low elongation, rarely loose under stress, light and flexible, impact resistant, cushioning external forces and conforming to the expansion and contraction of the paint layer , Can be rolled and transported, better than other materials, is the most suitable base material for oil painting creation. Linseed canvas has been used for hundreds of years.
