Using liquid mold silicone to create culture stones is an efficient and precise process, especially suitable for mass replication of decorative stones with natural textures or designed aesthetics. Below are detailed operating steps, material preparation, and precautions:

I. Material and Tool Preparation

1. Core Materials

• Liquid Mold Silicone: Choose mold silicone suitable for casting (recommended hardness 20-50 Shore A, with good flexibility and strong tear resistance, such as addition-cure or condensation-cure silicone; the former is more environmentally friendly but costlier, while the latter offers better cost-effectiveness).
• Curing Agent: A curing agent compatible with the silicone (typically added at 2%-5% of the silicone weight; refer to product instructions for specific ratios).
• Culture Stone Prototype: Options include natural stone (e.g., shale, sandstone), hand-carved models, or 3D-printed design prototypes (ensure the surface is smooth and free of burrs).
• Release Agent: Used to separate the prototype and mold; options include petroleum jelly, silicone oil, or specialized release agents (to prevent silicone from adhering to the prototype or culture stone material).
• Culture Stone Material:
  • Base Materials: White cement, ordinary Portland cement (to enhance strength), quartz sand, stone powder, fine aggregates (e.g., river sand, basalt particles).
  • Auxiliary Materials: Iron oxide pigments (for coloring, to mimic natural stone hues), water reducers (to improve slurry fluidity), short fibers (to enhance crack resistance).
