What is the difference between ordinary sludge and finely carved sludge?

Carved putty, a special modeling material, is actually an upgraded version of plasticine, but it should be remembered that carved putty and plasticine are completely different. Let's make a comparative analysis, and everyone will be clear at a glance. \x0d\\x0d\ 1. Ordinary modeling enthusiasts use "plasticine" to shape. Because of its characteristics, plasticine has a sticky mud feeling with oil. If you use it for a long time, it will irritate your fingers, affect your touch, and get your hands wet. I think this can be understood by friends who have played with plasticine. After the production is completed, it is only suitable for ordinary players as decoration, and it is not allowed to fiddle with it at will. When the weather is hot, the plasticine will become soft and even collapse and deform. Can't be used to make multiple identical models. \x0d\\x0d\2. The material used for professional modeling is "carved oil sludge", which is dark orange and hard at room temperature and can be used as "brick", hehe. When the temperature is above 50℃, the texture becomes soft gradually, and it can be molded according to the operation method of plasticine. Its advantage is that the softened carved oil sludge does not touch hands and does not affect the hand feel. The surface can be smoothed with your fingers. After cooling at room temperature, the surface will be bright and will not be deformed when playing. When plastic surgery is needed, you can use a hair dryer to heat the shape, and the shape will gradually soften and continue to shape. (Tip: After stopping heating, the carved sludge will cool down quickly at room temperature, but this is not a problem, and it will be very comfortable if you get used to it. ) \ x0d \ x0d \ Beginners usually carve a fine model with carving sludge combined with thirteen carving tools. The carved sludge is hard at room temperature, which will be softened by means of hair dryer, oven and boiling water, and then carved at room temperature. \x0d\ Repairing carved oil sludge is also very simple. Soften the sculpture where it needs to be repaired with a hair dryer. In addition, the carved sludge can be reused. \x0d\ The raw materials of carved oil sludge are mainly paraffin, stone powder and soil forest, and the shelf life is generally more than 2 years. \ x0d \ x0d \ Does it have to be very hot to knead and carve mud? Can it be polished when it is hard? \ x0d \ x0d \ Carved oil sludge will soften after being heated by a hair dryer, but it does not need to be heated to the point of soup. Hard ones can be polished, but greasy ones will stick to sandpaper, which is a bit troublesome!
