The average person can't tell the difference between chalk and pastel (also known as pastel pencil), and one of the main reasons is the problem of "translation". We usually call them "chalk", wrong!
Chalk in foreign language generally refers to Chalk, which is a tool used in daily life to write on the blackboard, and is familiar to the average person. Ancient chalk was usually made of natural chalk, but nowadays calcium carbonate (limestone) and calcium sulfate (gypsum) are mostly used, which is a white precipitate that is not easy to decompose, and the particles are larger than dust. It is mainly used to write on the blackboard, with white as the bulk, plus some limited colored chalk, but it is not suitable for painting. Generally 50 yuan a box, a few dollars can be bought.

The foreign language of pastel (pastel pen) refers to Pastel, and the general domestic translation also uses "chalk", which makes many people stupid and confused. Color chalk is a painting-specific piece of paint stick, or pencil form, including the crayons we are familiar with. Its color variety can reach hundreds of different colors, suitable for artistic creation, the effect is comparable to oil painting, watercolor works, and it is also an important kind of painting in foreign countries. Generally expensive, a box of 24, 36, 48 colors can reach about a few hundred yuan.

Therefore, chalk and color chalk (pastel) are different things, each with its own purpose. Why distinguish it? Because some painters paint "color chalk", but externally say that they use "chalk", people mistakenly think that it is a work drawn with ordinary teaching chalk and feel incredible, in fact, it is just a difference in painting materials. The painting effect of color chalk is naturally higher than that of ordinary chalk, especially its delicacy, ordinary chalk particles are too large and difficult to do.
However, after my research and attempts, ordinary teaching chalk can also play its characteristics and achieve a very good painting effect. Below is my chalk drawing portrait - C Ronaldo.
