Cups, dishes, and containers are often broken in our life. Although we clean them, we cannot clean minute pieces of glass perfectly. Those minute pieces of glass can be tread by adults or children, which causes a fatal risk. As the clay has a high concentration power, it can clean even minute pieces of glass. The natural material of clay is eco-friendly and does not need the electricity. It is easy to separate the broken glasses.
