Common hardness analysis of carved clay - Instructions for manual production

It seems that there have been many hand-made enthusiasts who have a lot of questions about the hardness of carved clay, what kind of carved clay is hard and what kind is soft? How to choose the smooth carving mud? What are the advantages and disadvantages of fine carving mud itself? Today, I would like to speak on behalf of one side and discuss with you. First of all, we look at the picture, the following three are the three kinds of fine sculpting mud I have (from top to bottom is fine sculpting mud A, fine sculpting mud B, fine sculpting mud S), should also be more common types of mud, there are other kinds of mud because I have not used it, so I will not comment on it after looking at the three kinds of mud, we basically remember the color and other characteristics. This kind of thing is originally from Taiwan, but we have no way to verify where it is produced in Taiwan, and obviously the types of fine carving mud on the market now are due to the seasonal needs of workers or due to the lack of strict quality control of ingredients, so I first want to say that, Please do not use the standard of this post to measure all the mud you see (I believe that someone must think that you can see it and then pick the cheapest one with similar length to buy it, unfortunately, I insist on not guaranteeing that I have not used something like this post, don't blame me for the wrong choice, ha ha), if there is any difference I insist on not being responsible. First, the color of the clay: many friends often judge the quality or hardness of the clay according to the color of the clay, unless you are a fixed buy, then the basic problem is not big, otherwise the comparability between the various homes is not 100%. What are the factors that affect the color of the clay? 1, the ratio of various raw materials in this batch of carved oil sludge (do not expect the worker to use a balance to give you the detailed proportion of the raw materials of the ton of carved oil mud, carved oil mud is not a chemical reagent, almost good) 2, the proportion of dyeing agents in this batch of carved oil mud (please allow me to call all the color paste, color paste and other things, don't tell me that you do not know the color, if you are willing to, Let the worker give you the production of green carved clay is not impossible, as long as there is a quantity) look at it this way, you still think how sure that a certain color is soft and hard? (Although the color judgment is used most of the time, but it is not absolute) Second, the ingredients of fine carving mud: I can only roughly say this, I only understand from the work, if the ingredients list out, it can only show that I am an idiot long, such a table for us is not too useful. 1, oil (may contain vaseline and other things, no oil how to call sludge? There is no oil that is soil) 2, stone powder (the specific is not known, just like ordinary soil is soil and sand, which is basically one of the main materials) 3, paraffin (what is specific is still uncertain, but it must be something similar to paraffin) Well, several main ingredients are finished, from this time we start to talk about the hardness problem PS: If you still struggle with the color problem, then please say these three things are what color? Oil: white slightly yellow, paraffin: paraffin also contains oil, but paraffin is white, stone powder: most of it is white, ha ha, so you understand? What's the use of color? Let's look at these three things. What's soft and what's hard? Obviously, the more fat, the softer it is, right? What about the stone powder itself? What is the hardness of the powder? What's the hardest? Paraffin, yes, paraffin is very hard, so we can draw the following conclusions: Premise: at room temperature before the paraffin melts; Paraffin wax: high hardness, easy to carve, but sensitive to temperature; Oil quality: high viscosity, soft, suitable for kneading, temperature is also good; More stone powder: it doesn't matter how much of this stuff, anyway, in the percentage, there is more of this and less of this, and this stuff is not sensitive to temperature or anything; And then finally the above three other things are mixed and cut into pieces is the fine carving mud: fine carving mud A: in fact, there are many paraffins, high hardness at room temperature, but the mutual adhesion is slightly poor, mainly carving, can be kneaded after softening; Fine carving mud B: moderate proportion of various materials, less paraffin, oil should be more, good adhesion to each other, at room temperature hardness in these three kinds of which is the lowest, after softening can be knead, not suitable for carving, suitable for simple modeling or people who like to knead, plastic sculpture techniques; Fine carving mud S: This is the new, of which the proportion of paraffin wax is very large, even very brittle when the day is cold, but the hardness is very high, and because the paraffin wax is much more delicate than the stone powder, so the whole fine carving mud is more delicate, after softening can also be pinched, but the hardening speed is fast, mainly suitable for carving, doing some accessories and the like is very convenient, and the adhesion is not good; Three kinds of mud are here, the details have been thoroughly analyzed with you, and finally how to use it is up to you, here is also to discuss a problem, that is, my evaluation criteria are paraffin wax more hard, but there are also friends who say that the kind of soft, which may only be said because paraffin wax is high sensitivity to temperature, So after proper heating immediately becomes less soft than the results of paraffin wax, even in the summer, it is likely that the fine carving mud S will not be so hard, for this case I can only say that all the contrast should be established at room temperature, in addition, the real which hard which soft and how important? We just need to know what the final characteristics of that ratio will be in the current situation, and how to choose is more important, what do you say? Ho ho
