As one of the traditional Chinese handicrafts, porcelain is deeply loved by people for its unique texture and color. However, due to various reasons, color difference will occur
between porcelain. Color difference is one of the important indicators to measure the quality of porcelain, so it is very important to detect the color difference of porcelain. Colo
rimeter is an instrument used to detect color, which is widely used in various fields, including the detection of porcelain color difference. This article will explain in detail the
reasons why porcelain has color difference and introduce how colorimeter detects porcelain color difference.
1. Reasons for color difference in porcelain
1. Glaze difference
Glaze is a transparent or translucent glassy thin layer covering the surface of porcelain. Its composition and thickness directly affect the color of porcelain. Glazes from different
batches or different materials may produce color difference.
2. Firing process
The firing process of porcelain will also affect its color. Different kilns, firing temperatures, firing times, etc. may cause porcelain to have color difference.
3. Lighting conditions
The color of porcelain will be affected by lighting conditions. Different light colors and intensities will make porcelain present different color effects.
4. Observation angle and visual error
Observation angle and visual error can also cause color difference in porcelain. The colors seen will be different at different observation angles. In addition, the human eye's
perception of color can also produce errors due to factors such as fatigue and emotions.
2. Methods of using a colorimeter to detect color difference of porcelain
A colorimeter is an instrument based on optical principles. It measures the color of the surface of an object to reflect its true color. The following are the steps to use a colorimete
r to detect the color difference of porcelain:
1. Select a suitable colorimeter
Select a suitable colorimeter according to your needs, such as a spectrophotometer, colorimeter, etc. These instruments can measure the intensity of the three colors of red, green,
and blue on the surface of an object to obtain color data.
2. Set a standard white light source
The standard white light source is the basis for the colorimeter to measure color. Select a suitable standard white light source, such as D65, to ensure that the measured color
matches the standard color.
3. Calibrate the colorimeter
Before color measurement, the colorimeter needs to be calibrated. This can ensure the accuracy of the colorimeter and reduce measurement errors.
4. Measure the color of porcelain
The instrument test port fits the area where the color difference needs to be identified, ensuring that the color of the area is pure color and the area is larger than the size of the
instrument test port for measurement.
5. Compare with the standard sample
Compare the measured color data with the standard sample to determine whether there is a color difference. If there is color difference, it can be evaluated according to the de
gree of color difference.
Conclusion
In summary, the main reasons for the color difference of porcelain include glaze differences, firing process, lighting conditions, observation angles and visual errors. Using a
colorimeter to detect the color difference of porcelain can improve the control and evaluation of porcelain quality. By selecting a suitable colorimeter, setting a standard white light
source, calibrating the colorimeter, measuring the color of porcelain and comparing it with a standard sample, it is possible to accurately detect whether there is color difference in
porcelain. This is of great significance for daily appreciation of porcelain, evaluation of the quality of collections, and control of production processes.
