With the increasing use of psychological sand table games, psychological sand table sand is an important part of psychological sand table games. How to choose safe, high-quality and environmentally friendly sand table sand is particularly important. One of the indispensable ingredients for game activities, how to configure environmentally friendly and high-quality sand table sand must be considered.
So, what kind of sand is used in psychological sand table games that is safe and environmentally friendly?
After 12 years of precipitation, and the guidance of psychology experts from Beijing Normal University, the answer obtained by Jingren Boren was: cleaned and disinfected natural sea sand.
At present, there are three main types of psychological sand table game sand on the market: mountain sand, quartz sand and natural sea sand. The colors are mainly yellow and white. Because of its natural environmental protection, the sand is uniform and round, the hand feel is comfortable, and it is dust-free. It is loved by the majority of users and is the most widely used; mountain sand and quartz sand are crushed and polished by mountain stone or quartz stone, and the particles have water chestnuts The feel is rough, the comfort is poor, and the mountain sand and quartz sand contain a certain amount of dust, which is harmful to the respiratory tract. Therefore, it is recommended that you prefer to use natural sea sand when purchasing sand table game sand.
So how to distinguish which kind of sand is natural sea sand? Summarizing the above characteristics, the following four simple methods help you choose high-quality natural sea sand.
1. Find: Natural sea sand is of course from the seaside. There are shells on the seaside. After long-term erosion and polishing by seawater, take a closer look at the shell particles in the sand.
2. Touch: Due to the long-term erosion and sanding of seawater, the sand particles are relatively round, the touch is delicate and soft, and the comfort is very good. Mountain sand and quartz sand are crushed and polished by machine using mountain stone or quartz sand. The sand grains have water chestnuts, which have a rough feel and poor comfort.
3. Look: Grab a handful of sand in your hand, and then let go to see if there is dust on your hand, because the human hand will secrete sweat, and generally will get some sand, and the sand will fall off when you clap your hands. There is no dust on the hand, which means that it is high-quality sea sand. If there is dust, it may be that the mountain sand or sea sand has not been cleaned.
4. Yang: Grab a handful of sand in your hand and slowly let go of the sand at a height of about 50 cm away from the sandbox to see if there is flying dust. There is no indication that it is high-quality sea sand. If there is flying dust, it may be mountain sand. Or the sea sand is not cleaned.
