Embodiment 1

[0051] (1) Each weighs 2g of bone glue particles and dissolves them in 100ml of water with a temperature less than 70°C, stirs evenly and disperses with ultrasonic waves, and prepares alums with bone glue proportions of 0%, 5%, 15%, 25%, 45%, and 65% respectively. Glue alum water, it is brushed respectively on the surface of the rice paper after pasting and mounting and dried. Brush the stone green pigment on the surface of rice paper ripened by different glue alum water respectively, the amount of brushing is 0.04 g, the thickness of brushing is 0.1 mm, and the temperature is 23 ℃, and the relative humidity is 55% and dried to obtain Samples after drying. Among them, stone green pigment was purchased from Suzhou Huacai Shengyuan Art Supplies Co., Ltd. Bone glue and alum were purchased from Beijing Jinbizhai Art Pigment Factory.

Embodiment 2

[0059] (1) Preparation of alum water: take 2g of alum and dissolve it in 48ml of water, stir evenly, and prepare alum water with a mass percentage concentration of 4%.

[0060] Bone glue preparation: Weigh 6g of bone glue particles and dissolve them in 94ml of water with a temperature lower than 70°C, stir evenly and disperse with ultrasonic waves, and prepare bone glue with a mass percentage concentration of 6%.

[0061]Glue alum water preparation: Mix the alum water with a concentration of 4% and glue with a concentration of 6% in equal volumes to form a 4:6 glue alum water. Brush it on the surface of the silk material and let it dry. Brush five kinds of pigments, cinnabar, azurite, stone green, realgar and ochre, respectively, on the surface of the silk material that has been cured by glue alum water, with a brushing amount of 0.04 grams and a thickness of 0.1mm. Dry it under the condition of 55% humidity to obtain a dried sample.

[0062] Among them, the five pigments of...

Embodiment 3

[0072] (1) Weigh 2g of cyanine paste pigments from 4 different batches of Suzhou Huacai Shengyuan Art Supplies Co., Ltd., and mix them evenly with 10ml of water in a mortar. Brush it evenly on the surface of the silk material matured by glue alum water, the amount of brushing is 0.05 grams, the thickness of the brushing is 0.1mm, and it is 23 ° C at a temperature, and it is dried under the condition of 55% relative humidity, and it is dried in the air. after the sample.

[0073] (2) Use a spectrophotometer (X-Rite SP64 portable spectrophotometer in the United States) to test the brightness L of pure white cotton cloth 0 * , red-green contrast a 0 * and yellow-blue contrast b 0 * . The test conditions are: the light source is a D65 standard light source, the observation angle is 10°, the light-containing method includes specular reflection; the spectral range is 400-740nm, the value interval is 10nm, the minimum measurement area is a circular area with a diameter of φ4mm,...

Abstract

The invention discloses a method for testing the friction-resistant color fastness of pigment for calligraphy and painting. The method includes the steps that Chinese art paper or silk is mounted with paste and aired, and the mounted Chinese art paper and the mounted silk are obtained; the to-be-tested pigment is painted to the surface of the mounted Chinese art paper or the surface of the mounted silk and aired, and an aired sample is obtained; the to-be-tested pigment painted to the sample is subjected to reciprocating friction through a friction head wrapped by lily-white cotton cloth, the brightness, the red and green contrast ratio and the yellow and blue contrast ratio of the lily-white cotton cloth before friction and after friction are tested respectively, the color difference value delta E is computed, and it can be achieved that the friction-resistant color fastness of the pigment is evaluated through the color difference value delta E. By means of the method, an objective test method is provided for evaluating the friction-resistant color fastness of the pigment for calligraphy and painting, and the testing method is accurate and reliable in data, small in experimental error and accurate and objective in testing result.

Description

technical field [0001] The invention relates to a method for testing the color fastness to rubbing, in particular to a method for testing the color fastness to rubbing of pigments for calligraphy and painting. Background technique [0002] Chinese ancient calligraphy and painting works are representatives of Chinese long-standing culture. With its unique style and charm, it has become one of the shining examples of oriental civilization. It occupies an important position in the history of world painting and occupies a large proportion in the collections of various museums in our country. . These precious works of art left by Chinese painters in the past have extremely important historical, artistic and scientific values, and are also important materials for studying the history of ancient Chinese art. The art of painting is inseparable from the rendering of pigments. The interpretation of the word painting in ancient China is related to the use of colors. For "Danqing hand...
