Abstract: To form a stable coating layer painted in azurite and malachite with glue during traditional dancheong (Korean decorative coloring on wooden buildings) construction, it is necessary to verify an appropriate concentration of glue solution.To evaluate the stability of the coating layer painted in azurite and malachite, this study set the concentration of glue solution in the glue/alum mixture solution and vehicle at 3.0%, 6.0%, and 9.0%, and coated azurite and malachite with the glue/alum mixture solution and celadonite, and then conducted artificial degradation and outdoor weathering tests on the colored azurite and malachite.A relatively stable coating layer was formed in the specimens painted with a 9.0% concentration of glue solution in the vehicle for azurite and 6.0% and 9.0% concentrations of glue solution in the vehicle for malachite.For azurite, the coloring was found to be poor as its particles were larger than those of malachite and its particle size distribution was not consistent.It was concluded that the concentration of the pigment in the vehicle may vary depending on the particle size, shape, and particle size distribution of the pigment.
