Tampera oil painting techniques

Tampera oil painting techniques Tampera painting media - emulsion is divided into natural latex and synthetic emulsion two categories. European traditional tampera painting uses egg tampera emulsion, modern painters also use casein emulsion and methyl cellulose emulsion. Its preparation method is as follows: (1) Egg tampera emulsion (1) Waterborne egg yolk tampera emulsion: an egg yolk to add equal or half of the water, and then drop a few drops of white vinegar, emulsification and corrosion. ② Oily egg yolk tampera emulsion; (1:2) Dama glazing oil and flaxseed oil are mixed at a ratio of 2:1. Take two teaspoons of the mixture and add one egg yolk, then drop in a few drops of white vinegar. ③ Whole egg tampera emulsion: that is, egg white and egg yolk can be used together instead of egg yolk. According to the painter's needs, water-based or oily whole egg tampera emulsion can be prepared according to the above two methods. Another preparation method for whole egg tampera emulsion: one whole egg, half (1∶2) dama polishing oil, half (1∶2) linseed oil, and one part water. (2) casein emulsion Heat 50 grams of casein to a boil in an electric pot containing 125 ml of water, then add 15 ~ 20 grams of ammonium carbonate (melted with warm water), stir continuously until casein is fully dissolved, then add 125 ml of water to make glue, add 1% of lead white for anticorrosion. As a water-based emulsion, the glue can be directly used for color mixing and painting, and can also be added with appropriate dama polishing oil and linseed oil. (3) methyl cellulose emulsion Take 31 grams of methyl cellulose, add 2.2 liters of water, stir and dissolve before use. When used directly for painting, it is best to mix half or equal amount of latex. An oily methyl cellulose emulsion can be prepared by adding one part methyl cellulose to half part Dama polishing oil, half part flaxseed oil and one part water. Tampera's method of painting: (1) more hard supporting materials such as wood boards are used, and a layer of gauze or other cloth is affixed to the bottom plate. (2) chalk bottom or gypsum bottom. No oil base is used. (3) Paint with tampera emulsion and toner. (4) draw a rigorous and neat sketch on a sketch paper as large as the painting, and then copy it to the bottom of the painting, spraying thin alum water can be colored. In the painting process, it is best to use tampera emulsion on demand, because this emulsion will deteriorate over time or oil and water separation phenomenon. Dip and dilute the color according to the coloring needs. The first step is to paint the general color with a flat pen in watercolor painting mode, and then use a small brush with a thick small brush to gradually apply color and shape. Due to the semi - transparency of tampera pigment, it is not easy to evenly apply color in a large area, so the use of cover color and small line arrangement techniques for detailed description. Apply color principle is by shallow reach deep, thin after thick first. Tampela's painting features: fine description of objects, and can maximize the maintenance of bright color, and dry fast (after a few seconds dry), can be repeated multi-layer drawing.
