Art: How do metals, glassware and transparent plastic objects express their texture?

Metal, glassware and transparent plastic objects are common objects in still life paintings. One of these objects is a transparent object that depends on the color of the environment, and the other is an object with monotonous color and strong reflection. These two kinds of objects can enhance the vitality of the picture, enrich the rhythm of the picture and the texture of the object. Colorless glassware and transparent plastic objects are colorless, but they still have a faint sense of color. Their color changes are mostly the colors of the background and other objects. When assembling still life, in order to enhance the sense of transparency and enrich the picture, transparent objects will be filled with some colored liquids. In order to blend the transparent object with the surrounding environment and show its texture, firstly, the opaque part of the transparent object is colored, and then the transparent part is gently washed with clear water according to the shape of the object, and then the shape of the edge of the object is determined while it is wet. Point highlights should be few and fine, and the highlight colors should be different in different environments. Metal objects reflect other objects around them more strongly than glazed jars. Some objects are made of the same material as mirrors (such as stainless steel) and have strong reflectivity. To express the texture of such objects, the color change should not be too great. Generally, the change of light and shade is increased in the same color, but the color tendency of the reflective part should be clear, and the pen should be sure when it is prominent.
