Restoration of colorful murals in Longmen Grottoes and non-heritage craftsmanship of painting colors

Abstract

The invention relates to an intangible cultural heritage process for repairing and coloring a colored mural of the Longmen grottoes. The intangible cultural heritage process for repairing and coloring the colored mural of the Longmen grottoes comprises the concrete steps of surveying and photographing a grotto sculpture on the spot, importing a photo into a computer, then calculating the dimension of the grotto sculpture, and calculating a dimensional proportion length; designing a dermatoglyphic pattern color by referring to the colored mural of Dunhuang at the same period, repairing a damaged part of the grotto sculpture, and manufacturing a digital model with a three-dimensional (3D) format; outputting, enlarging and printing to a broadsheet according to the digital restoring model with the 3D format, and drawing a manuscript rough draft according to a grotto sculpture restoring model; and carrying out digital coloring repair on the manuscripted grotto sculpture with different forms, copying onto a canvas, and completing the repair on the grotto colored mural. The colored mural of the Longmen grottoes repaired through the intangible cultural heritage process for repairing and coloring the colored mural of the Longmen grottoes provided by the invention reproduces a colored original appearance of the Longmen grottoes; and with a special self-made rock color oily pigment for mural repair, the mural is ensured to be rick in saturation, simple and unsophisticated in color, rich in texture gradation, high in art decoration, thick in texture, difficult to discolor, resistant to light and sun, and capable of being stored for a long time.

Description

[0001] Restoration of colored murals in Longmen Grottoes, intangible cultural heritage crafts of painting colors technical field [0002] The invention relates to the field of restoration of color murals in grottoes, in particular to the repair of color murals in Longmen Grottoes and an intangible cultural heritage technique for drawing colors. Background technique [0003] Grotto murals are usually made of grass and mud on the uneven rock walls after the caves are excavated, and then painted. For the murals of the Northern Wei, Western Wei, and Northern Zhou dynasties, two layers of wheat straw and mud were applied, without the background color, directly Paint on rough mud walls. The grass mud layers of the ground wares and the paint layer and the grass mud layer are relatively closely combined, and generally there is no peeling and peeling lesions, but small cracks appear on the local wall surface; There are 3 to 4 layers, and the types of mud layers increase. In addition...

AI Technical Summary

Problems solved by technology

In some murals, the mud layer is too thick or the murals with multiple layers added to the previous generation of murals by later generations. Due to the influence of humidity, earthquakes, rock cracks, etc., some of the ground poles are separated from the rock wall, forming cracks and hollows. There is always the danger of a large area falling off

[0004] Ji Yunbo, the non-heritage inheritor of Longmen Grottoes wood carving skills, found that when he studied the restoration of color murals, the existing restoration technology of color murals in grottoes is to directly draw the original cave line draft on the stone slabs and then paint, which is widely used in ordinary The murals are repaired, but it is impossible to paint the stone statues without color, and the existing rock color pigments are water-based pigments, which are not rich in hue, too bright in color, dull in texture, easy to change color in the sun, not light fast, and not fast to light. New techniques are needed to solve the problem of painting colored murals for colorless Longmen Grotto statues
