Silicone rubber is not a common sculpture material. It is sticky, and when it is cured, it eliminates the acid smoke of the ascetic, and you can\'t handle it with your hands. This instructable is about the various unusual techniques I have developed for using it. Silicone rubber is usually used as a sealing material for windows, etc. You can buy it at 10. 5 fl. oz. The grease barrel in a hardware store costs about $4, so it\'s not expensive to use. It has a limited variety of colors such as black, white, brown and transparent. I always buy transparent silica gel and color it myself with powder paint. You can buy some cheap powder paint in some hardware stores to color the cement. Get a wider range of colors from some art suppliers. ( Google searches for \"Artist powder pigments\" from some online sources \". ) Here you will find photos of some of my silicone rubber sculptures and a brief description of how they are made. Most sculptures are built directly. Some are made indirectly with molds. The belly dance below is a complex work made with several molds. I will explain it in more detail later. I don\'t know the ecological side effects of producing silicone rubber or the final breakdown of it. It\'s not when healingtoxic. It came out of the box as a sticky paste and smelled bitter acid (vinegar) It will soon heal and become a rubber-like substance. It sticks like crazy to some non Porous materials such as glass, metal and more silicone rubber. It does not stick well with other materials such as wood and some plastic. My favorite working surface is polyethylene plastic because it comes off right away when the silicone is hardened. Plastic garbage bags are polyethylene plastic and can be extended out on boards or tables as working surfaces. I bought some thick polyethylene a few years ago that doesn\'t need to stretch. A thick polyethylene plastic kitchen cutting board was found recently and I intend to use it for working surfaces later. If you apply it to your skin, wipe it off right away. Too long skin contact time can cause your skin to peel off. The life of silicone rubber is very good. As a seal, it is guaranteed for 30 years outdoors. Interior sculptures should be easily preserved for a lifetime. The palette knife used by the painter is a very useful tool for spreading silicone rubber. They are like small gray Trojans. Some are made of plastic and some are made of metal. Some silicone materials always seem to harden, so you have to scratch them occasionally with a knife. You can spray the silicone directly from the box onto the part you are making and apply it around with a color knife. You can also spray clear silica gel on a disposable paper palette and use a palette knife to mix powder pigments in it for color effects. Because the silicone is hard fast, so do it quickly. You can extend your working hours by packing the silicone in the syringe with a color adjustment knife and then squeezing it out of the syringe. This will be introduced in the next step. The palette knife is one of your most useful silicone rubber sculpture tools. In the air, silicone begins to harden rapidly. To extend your working hours and learn more details, it is sometimes useful to color the silicone and pack it immediately in another closed container syringe. The air does not reach the quality inside the syringe and you can squeeze out what you need from the end. It\'s like a tiny oil bomb. You can purchase large syringes at a pet shop or at a veterinary store. For standard syringes with metal needles, you cannot use the needles they come with for detailed work because the diameter of the holes is too small to get the silicone through. You can make disposable plastic needles with larger pores with some cotton ear swabs with plastic stems, or you can use syringes without needles. See next for tips on how to make disposable needles. Recently, I found these curved plastic needles in the pet shop. They are used to feed birds and small animals. For extrusion of different sizes, the tapered tip can be cut in different positions without the need to make a special tip. The rest of the syringe consists of a transparent plastic bucket and a piston part with a rubber head. They can be cleaned and reused multiple times, but will eventually become unavailable and need to be replaced. I made some special cleaning tools with wire to clean the nozzle end tube. One straight or curved wire cleans the nozzle, and the other wire, shaped like a miniature hoe, wraps the silicone around the barrel. The syringe barrel is polyethylene plastic and the hardened silicone is not good to stick to it. Pumping the piston into it several times will clean up most of it. Just wipe the piston or peel off any rubber parts to clean the piston-up. Q- Tip brand cotton swab uses fiber material on the stem. They may be the first choice to clean the ears, but they are useless for making the syringe tip. A cheap cotton swab uses a small diameter plastic tube in the stem. A few years ago, I used this material to make special needles for the syringe. I took out the cotton from the end and crossed the pipe with thin lines. By carefully softening the plastic on the low propane torch flame and pulling the end of the pipe in the opposite direction, the center area is lengthened and the diameter is reduced until the wire inside is reached. After the stretch plastic cools, I use a sharp X- Acto knife makes two needle tips. The reduced diameter part will pass through the hole at the end of the syringe, but the complete The diameter part will be stuck in the hole. I use it as much as I can and when it gets blocked I just discard it and load the other one. To make a photo for this instructable, I tried to make more disposable needles today but failed. The tubing wall is thinner than I used. These photos will let you know how to make them, but the needles shown are bad examples of what they should be. You have to find a better quality cotton swab to punch your needle out. This is a strange \"taxi horn\" like an antique car \". You squeeze the rubber bulb, and the air vibrates the Reed and makes a bell sound. These colors are silicone rubber with powder pigments, not paint. I made a light bulb on a toy balloon. After the silicone hardened, I popped the balloon and took it out. Most of these statues are solid silicone rubber made of silver welded stainless steel electrode brackets. Where the wooden base is used, drill the hole and then extend the gun holder onto the wood. Perhaps, I am too fascinated by bronze sculptures. I seem to have made a lot of imitation bronze with silicone. I bought a can of bronze powder from a marine store a few years ago. Mix it with silicone and look like bronze. Bronze powder is made by an interesting process. In this case, there are arc welding machines with two rolls of wire, such as sewing wire. The wires were sent to where they met and the arc melted them. A compressed air jet in the liquefaction zone spews a spray of micron-grade particles. For example, you can \"draw\" something like Apple to make a metal mold. You can even spray paper and it doesn\'t burn because every drop of liquid metal contains very little heat. If you just spray the metal into the room, the water drops will cool down and fall on the floor where the powder is collected as dust. This abstract sculpture Monument, about 3 feet. tall. I say \"yes\" because it\'s not a strong material combination and it breaks down when someone hits it with a car. The sculpture is made of foam plastic and silica gel glued together. Bronze Skin- Then color silicone is applied to the foam plastic. Foam is easy to break when it bends, but if you laminate non-foam Stretch the skin to it, like cloth, and you can prevent the cracks from starting. If you can\'t start, you can\'t continue. the piece won\'t be broken. Silicone rubber stretches so it can\'t prevent cracks from starting. This is not a good technology if power is important. Still, I love this sculpture and can imagine it on a huge scale where one can walk in. These hanging fish are carved out of foam plastic and laminated with a cloth in a transparent acrylic medium ( Media of artist painting). The fins are made of silicone rubber and cloth. On a non- Paste the polyethylene surface I spread the cloth with a color adjustment knife and cover it with transparent silicone. After it hardened, I peeled it down, turned it over and made the other side. The silicone penetrates the fabric tissue, so the fabric is mechanically locked. After making the material sheet, I cut the fins with scissors and added the ribs with a syringe. I used a similar technique and made a rubber shower curtain using a fiberglass mat and silicone. Fins penetrate the cloth skin and cut the skin with a knife first. Using a soldering iron with a flat blade, I melted the slots in the foam body where I could set up the fins with more silicone. These fish are very light. The weight, because of the skin of the cloth, is really hard to break. There are different ways to make hollow shapes with silicone. These sculptures were originally made with water. Foundation clay on PVC pipes. They still have calcium carbide inside. A layer of silicone rubber is covered in clay. When silicone is hardened, cut it with a knife to remove the clay inside. Then repair the slit in the silicone with more silicone, and the surface is colored. Ordinary paint will not stick to silicone rubber, so you have to make your own \"paint\" with transparent silicone and powder paint \". You can make hollow shapes on balloons, such as squeezing bulbs. Another technique is to use foam as the core and then introduce a little solvent, such as paint thinner, to dissolve the foam and hollow the core. Even with strong solvents like paint or acetone, silicone rubber does not penetrate. These big fish-hanging sculptures are soft sculptures. If they fall, they will not be hurt or hurt anyone. There is some flat PVC material as a skeleton which makes some sidesto- Side bend like a real fish body but not upand-down flexing. Mattress foam is glued to both sides of the mattress with silicone. A very sharp pair of scissors is needed to cut the foam, so I sharpened a pair like two blades. Carving inside the mouth is quite easy because the mouth is curved and can be opened. Bronze Skin- Apply the colored silicone to the foam surface with a color adjustment knife. Add transparent silicone directly from grease barrel. I like the idea of hanging fish. They seem to swim in the water. I have never found a way to get a smooth surface directly on a sculpture, so I use a plaster mold to mimic a smooth bronze surface. Silicone needs to lose acetic acid to harden and cannot be done in a closed mold. In addition, a large amount of silicone will harden forever, because acetic acid must find a way out from the core. I made these sculptures with open molds. The plaster mold is first dried, coated with shellac, and then coated with mold release agents such as wax. When dry, I \"painted\" The inside of the mold with bronze silicone, and then filled the rest of the mold with a \"bird\'s nest\" clearly squeezed directly from the grease barrel. Due to the confusion of the extrusion there is air passage through which the core can be ventilated and the whole thing can harden in a reasonable amount of time. The \"frustrated artist\" who pulled his hair was made with an open mold. Later, I applied a layer of silicone on the back to seal the air cavity. Belly dance is a much more complicated work. A total of 40 inch high. The cylinder at the bottom is hollow and is a piece of PVC sewage pipe, and the three figures above are made of open molds respectively and then glued to the tube. The figure at the top is a circular sculpture, consisting of two and a half, and then carefully connected together. In her center there is a flexible vinyl tube with a 1/4 steel bar inside the vinyl sleeve to provide rigidity as she is very flexible on her own. The idea is to one day install a slow motor on the base attached to the rebar shaft. She should do a good belly dance with hip movements. The idea was inspired by a small rubber hoochy When you turn the crank, I once saw the coochy toy that was dancing. Maybe I will finish it one day.
