Manufacturing method of special rosin block for erhu

Good rosin powder is small and easy to fall off, whereas it is large and difficult to fall off. So, can you make good rosin yourself? The answer is: yes. Let's talk about how to do it. First buy a piece of raw rosin (usually a few dollars, light yellow and transparent in color) from the farmer's market. Second, take an iron container, put the rosin in it, put it on the fire, and cook it over medium heat (without adding anything) until the rosin is brown and opaque (usually a few minutes). Take a small paper box commonly used in life, such as a small medicine box, and turn down the fire. Otherwise, the rosin will cool quickly. Put the boiled rosin into the paper box bit by bit with a dry spoon (which can't hold water), not too fast, and the bottom of the paper box must be closed (be careful not to burn during this process). Boiled rosin is used up, and more than a dozen pieces of rosin can be made. When you use it in the future, just tear off the paper on it.
