Imitation porcelain sand is children's play sand with simulated porcelain touch, made from food-grade quartz sand and polyethylene resin through high-temperature melting, granulation and polishing, with particle size 0.3–0.8mm, Mohs hardness 2, no edges and no stickiness. It is non-toxic with dust emission ≤0.01mg/m³, suitable for sensory training and creative stacking of children over 3 years old. Its porcelain-like smooth touch can improve children's sensory sensitivity, with good particle fluidity, easy storage and no stickiness, making it the preferred category of play sand for young children.
