1、? outline
Because the bone is hard, in order to ensure the normal work of the engraving machine, connect the 220 volt power supply to the voltage regulator and adjust it to 220 volts. First sharpen the blade, and then carve the outline of the basic shape on the main frame with a four-corner carving knife. This is the so-called analysis.
2、? chisel
Use a flat chisel to remove excess material from the large blank of the model. Because the bone is hard and brittle, you will chisel through it if you are not careful, so be very careful, hold the chisel at a 45 angle, don't use too much force with the hammer, and the chisel surface should be smooth.
3、? systems modelling
The outline of the main frame has come out and needs to be modeled on this basis. Modeling can be done by sinking into the ground, adding the original outline to the outside of the pattern and sinking deeply. Make the pattern distinct, concave and convex, presenting relief effect and strong three-dimensional sense. Deepen and modify the original notch at one end of the bone to make the notch smoother and more natural.
4、? Mild activity
Put on a peach-shaped meat cutter and polish it. The edge of the peach-shaped carving knife surface is smooth, and the skin can be polished off without destroying the original shape. It is necessary to walk the whole modeling surface and concave line to make the whole main frame smooth after photographic development.
5、? Key work
The edge of the round-headed carving knife is flat and can be used to carve shallow and wide lines and points.
6、? finish
Use a small triangular carving knife to portray the shape, and the carving should be smooth and smooth.
7. drift? white
After all parts are carved, they should be bleached. 0.3~0.5 kg of hydrogen peroxide is added into 3 kg of clean water and stirred evenly. Put the processed bone carving semi-finished product into the pot, and then you can see that there are bubbles in the water, which is the oxidation reaction between hydrogen peroxide and the bone surface, which makes the bone bleach. After soaking for 12 hours, put on rubber gloves, take out the bone carving semi-finished product, rinse it repeatedly with clear water, and dry it after rinsing. If the finished bone carvings we have made are not colored, then these semi-finished products can be assembled after drying. If the finished bone carving is to be colored, then the next step is to treat it with acid bite.
8. acid? bite
During acid biting treatment, 0.03kg hydrochloric acid is added into 3kg clear water and stirred evenly. Put the semi-finished products to be colored into the basin. The carved bones were soaked for 2 hours and then taken out. Rinse repeatedly with clear water, dry after washing, and prepare for coloring. After acid bite, there are uneven pores on the bone surface that are invisible to the naked eye, and the pigment is easy to eat and not easy to fade.
9. Are you going? colour
Transparent watercolor pigments for coloring bone carving works can be bought in general stationery stores. After 2 hours of coloring, it can be assembled.
10. Mosaic plane aerial photograph
Prepare a wooden or plastic base, which is slightly smaller than the main frame of the bone carving. Make a hole under the main frame of the bone carving, and also make a hole at the relative position of the base. Take a small bamboo stick with a diameter slightly smaller than a round hole, foam one end with white latex, insert it into the base, and saw it off at 1 cm. Put it aside and let the white latex set for a while. Finally, spray a thin layer on the finished product by automatic hand painting to prevent fading. In this way, the art of bone carving is completed.
Above, I introduced the steps of bone carving in detail for you, so bone carving is a modern art, and it seems to be a beautiful thing now, but it was made by our ancestors after severe natural struggles and great difficulties in ancient society with low productivity and technical level. Now that we have machines and the help of science and technology, we should continue to carry forward this carving art. Secondly, after you have carved it, you should always maintain it. Because it is made of bone, it should be kept indoors at a suitable temperature as far as possible, and wiped with a dry and soft Puckilo when cleaning. number
