B, clay tools, basically buy the cheapest, the utilization rate is not high, and only one or two are often used; I thought they were all useful at first, so I bought a dozen, but most of them have not been used yet. This may be the price of experience.
C. Direct-injection lighters, which are used to repair the details of oil sludge sculptures and polish the surface, are one of the essential tools.
?
D, carving knife, this is the main tool, not only for clay sculpture, but also for carving details after turning over the mold. Choose a better one and get twice the result with half the effort.
The tools needed are: file, fine sandpaper, art knife, diagonal pliers, etc. Some of them can be found at your side when you need them, such as some children's toys. The best tool you can think of is to hang the phone upside down.
F, silica gel is used for mold turnover, hence the name Siyi is used for mold turnover. This bucket is 5KG 198 yuan, which is quite expensive, so it is a good idea to think of some fuel-saving techniques when using it, such as online teaching, using sludge as the bottom, putting the model on it and pouring silica gel, which can save half. I learned this later, and it wasted a lot, which was the experience cost. You should thank me, hehe!
G, AB water (also called resin): one barrel 1kg, and one group (two barrels of AB) is about 80 yuan, which is a manual turnover molding material. After the silica gel mold is made, two liquids AB are mixed according to the ratio of 1: 1 and poured into the mold for molding. When operating this step, the most important thing is to grasp the time, because the two liquids will start to solidify in about 1 minute after mixing, which means it is useless. Therefore, preparations should be made in advance, the molds to be watered should be in place, and the watering should be completed within 30 seconds. This has fulfilled an old saying that time is money.
H, vacuum box, introduced here, I have to boast that this is a product independently developed by me and the result of waste utilization. I'm preparing to apply for a national patent, hee hee. This tool is used when the resin is poured into the mold, and some air can't be exhausted, so there will be holes formed by bubbles on the surface of the mold. These holes often appear in smaller details, such as nose, fingers, hair tips, etc., which greatly affects the appearance. This tool can solve the above situation well. Through the vacuum box, the gas that cannot be exhausted can be completely exhausted, and the surface is no longer pitted. However, because the box is relatively small, it is currently limited to the operation of small pieces. But the big one has bubbles, so don't worry. Let me introduce the folk prescription.
4. After the tools and materials are ready, just choose a good picture on the Internet as a model and start your DIY journey. Before you start, watch more tutorial videos (there are many on the Internet) and do research as you go. I believe that there will be satisfactory works soon.
5, a, the carving process skipped the word 10000, and the next thing is to make the mold. The following is my personal operation method, which is really immature. It would be my great honor if I could help you.
This is the attachment fulcrum of sludge after molding, which is used as dumping port and exhaust port.
B, use some cardboard such as card edge as the mold box, and paste other parts with fulcrums, as shown in the above figure (but pay attention to control the number of fulcrums within 2 as far as possible, unless the size is too large, you will find that it takes some effort to remove these fulcrums after resin molding).
C, mixing silica gel with curing water according to the ratio of 100: 2, and then pouring into the mold box until the model is submerged, and then molding can be performed after waiting for one or two hours. This is a mold made partly of silica gel.
D, after solidification, the mold can be opened. At this time, you will know why I have to post the fulcrum in advance. This fulcrum serves as a watering hole and an exhaust hole, and is also used to show the position of the model. You can clearly understand the cutting position when opening the mold.
E. The next step is about the remedy of potholes. Here are some pictures with pits. At this time, you can clearly see the large and small pits. It is basically difficult to avoid bubbles without a vacuum box, but it doesn't bother us. The method is very simple, as shown in Figure 2. Use a file to grind some resin blocks into powder, fill them in the holes, then dry them with 502 glue and smooth them out. Fill in more points in the carved part and carve the shape with a carving knife.
F, the next step is polishing. File the coarse ore first, and then polish it with fine sandpaper. See the effect at this time.
