Technical Field

The invention belongs to the field of wood treatment, and particularly relates to a method for drawing by using pear tree bark.

Background

The natural materials of bark, grass root, shell, ricepaperplant pith, wheat straw and wood stone, etc. are made into the artistic leather by utilizing their natural texture and grain through a couple of designs and processes. They not only show beauty with their peculiar charm, but also embody the human love of the emotion of nature and the intelligence of reforming nature with their material.

The bark picture is various semi-relief type pictures which are creatively and skillfully combined and stuck by utilizing the natural shape, different colors and textures of the bark, namely the bark picture mainly takes landscape pictures as main pictures. The tree bark paper is painted, the pigment is mainly mineral pigment and plant pigment, and the content is mainly portrait or life scene. The Jilin bark picture adopts birch bark as a raw material, has strong contrast of thickness and fineness, is tough like leather, and is easy to be cut; although the fiber is continuous like hair, the fiber is soft and moist like the original fiber for many years, is easy to bond and dye, and is very convenient to manufacture.

The pear tree bark is thick, and the inlayer is more smooth moreover, can be used for processing bark picture or other handicraft, but the pear tree bark improper processing can lead to the fracture, and the value descends, and is perishable, difficult the storage.

Detailed Description

The present invention will be described in further detail with reference to examples. The reagents or instruments used are not indicated by manufacturers, and are regarded as conventional products which can be purchased in the market.

A method for drawing by using pear tree bark comprises the following steps:

step 1, selecting a bottom plate according to the content of a picture;

step 2, selecting pear tree barks as raw materials and carrying out pretreatment;

step (1): pretreatment of pear tree bark: selecting pear tree bark, scraping off surface bark to phloem, peeling off the whole piece, cooking at 100 ℃ for 2h for insect killing and sterilization treatment, then putting into 4 wt% sodium carbonate aqueous solution for water cooking for 5min, rinsing with clear water, and air drying;

step (2): treating the pear tree bark: soaking the pear tree bark dried in the step (1) in a 10% hydrogen peroxide solution for 2h, taking out, rinsing with clear water, and air-drying in a cool and dry place;

and (3): spraying clear water on the surface of the pear tree bark treated in the step (2), wherein the clear water can be sprayed on the surface locally or completely, the spraying can be carried out according to the contents of pictures, and certain textures can be formed according to the spraying range during subsequent baking and burning;

and (4): and (3) baking and burning the pear tree bark treated in the step (3), wherein a certain amount of water is sprayed on the surface of the pear tree bark in the step (3), so that the surface with more sprayed water is baked and burned with different baking and burning degrees with the surface with less sprayed water under the same baking and burning conditions, thereby forming a certain texture. The texture can be directly applied to the subsequent drawing process, and the picture is drawn through the texture. The texture can also have certain influence on the pigment coated during subsequent drawing, and the color difference can be generated at different baking and burning degrees, wherein the color difference comprises the degree of coloration, brightness and the like, and the texture also provides some auxiliary effects for subsequent drawing.

And 3, cutting the pear tree bark pretreated in the step 2, and drawing on a cambium by using a nicking tool or a painting brush.

The pear tree bark painting obtained by the painting method has better painting layering and aesthetic feeling than the effects obtained by the common painting method, and the quality of the formed painting is improved because the pear tree bark is treated in the painting process.

The protection of the present invention is not limited to the above embodiments. Variations and advantages that may occur to those skilled in the art may be incorporated into the invention without departing from the spirit and scope of the inventive concept and the scope of the appended claims is intended to be protected.
