200 points for the steps of turning over the sculpture mold

Gypsum turning:

Adjust the gypsum slurry, put water first, and then sprinkle the gypsum, the first time the gypsum must be thin, evenly covered to the surface of the mud, there must be no bubbles, the hemp fiber is dismantled and the hemp fiber is stained with more viscous gypsum, reinforced according to the divided block, covered with the entire clay sculpture, and the gypsum is completely solidified after the whole is removed and dried.

Silicone mold turning: There are a lot of domestic silicone bubbles, it is recommended to put less in the first layer of curing agent, carefully brush a layer with a wolf pen, brush the details to the point, brush off the big bubbles, and then go on the second time. Or you can blow with an airbrush, mainly depending on what material your figure is made of, if you do it with clay, you can only blow with an airbrush, the brush will destroy the details, how to use soft pottery or American soil to burn hard, you can use a brush, the effect of the brush is better than spraying. If silicone turns silicone, no matter what kind of release agent is not effective, it is not ......Try to make the contact surface of the silicone smaller, or directly on Vaseline, and spray more points of oil-based release agent, and the details must be sprayed, anyway, it is not easy to get rid of ......If you really can't get rid of it, soak it in warm water, and you can get off a little better.

If you turn over the silicone mold, it is best to use gypsum to make an outer mold, which is not easy to deform, and you can go to the electric mule to "Sculpture Carving Techniques".

There is also resin turning, and the main thing is to eliminate air bubbles!

Carved with clay.

Then use gypsum or FRP to reverse the mold, and then reverse the real thing.

20 yuan to buy a book for the introduction to sculpture, even the steps are even **.

It's better to find someone who knows how to do it, I can't do it myself, it's really not clear what I can't say.

If I were to tell you in writing, it would be very complicated, and I would love to dictate it...

1. Divide your work into two parts with inserts, of course, depending on the specific shape of your work, there are also three to four parts.

2. Draw a layer of separator on the red clay, such as: laundry detergent water or soapy water.

3. The first layer of live gypsum is relatively thin, the second and third layers are slightly raised, pay attention to the degree of thinness, and you had better apply more to some deeper places.

4. When it is dry, the mold should be divided, and then the red mud inside should be taken out and the mold should be repaired.

5. Then brush the mold with the separator, and then close the mold with iron wire, and close it tightly.

6. Pour the gypsum slurry into the mold, pick up the mold and shake it, and repeat it, this step is very important to make it bubble.

7. After everything is done, wait until it is completely dry before using a tool to remove the plaster on the outside, taking care not to hurt the inner layer.

You can first use the real thing to make a first mold out, and then make a mold out of the mold silicone brush mold or inverted mold in it, and then you can pour the material directly into the mold for any sculpture and crafts you want to do, and you can mold it, and use HF-318 and HF-308 to turn the mold has its own advantages.

It depends on whether you can use only one mold for that sculpture. If you can, it's better to make a plaster mold for it first, and then put soapy water in it after the mold is dry, then grout, and then demold, reassemble and repair it.
