AN EXPERIMENTAL STUDY ON COLOR DEVELOPMENT FROM MIXING PIGMENTS AND ANTIOXIDANTS IN CHINESE LACQUER

Abstract

This study aimed to develop colorants from Chinese lacquer by incorporating pigments and antioxidants to evaluate the quality of surface coatings for contemporary handicraft applications. Natural pigment (pandan leaf powder) and inorganic pigment (chromium oxide green) were combined with vitamin C (L-ascorbic acid) as an antioxidant. The findings revealed that the formula containing chromium oxide green produced a vibrant, deep green shade but exhibited poor adhesion, resulting in pigment flaking. In contrast, the pandan-based formula yielded a lighter green tone but showed better surface adhesion and demonstrated greater safety potential for practical use. Vitamin C played a key role in stabilizing color and preserving brightness in all formulas. Overall, this study provides insights into the sustainable development of natural color materials that integrate scientific innovation with traditional Thai craftsmanship, promoting safer and more environmentally friendly practices in artisan and jewelry work.
