The method is as follows:
1. First, prepare a container and dig two spoonfuls of edible baking soda with a spoon. Baking soda is usually found in the kitchen at home. If there is no baking soda in the kitchen at home, it is also sold in the supermarket, and the price is not expensive.
2. Pour some water into the container to melt the baking soda, preferably hot water, not too much water. Make saturated baking soda solution.
3. Pour the detergent into the container. Detergent brand is optional, mainly used to increase the lubricity of crystal mud. This detergent still has its own color, so this crystal mud saves pigment.
4. Next, add contact lens care solution to shape the mask. If you don't have glasses care solution, you can put borax water or some brands of laundry detergent.
5. Continue stirring. It is found that the solution in the container will become sticky in a short time. At this point, the crystal mud has been formed, but it is not transparent.
6. The reason why the crystal mud is opaque is that a large number of bubbles are mixed during stirring, so it is put in a container and left to stand for about 2 days to let the bubbles disappear naturally. It is best to seal the container. If it is not sealed, the water will evaporate and the crystal mud will dry.
7. After almost two days, I got a very clear and transparent crystal mud.
