Beads formation using 50% clay

  • Making the solution of 1.25 g PVOH, 40.417 mL of 3wt% clay, 15 mL 12.1M HCl
    • Mass of PVOH: 1.2503 g
    • Mass of clay: 1.25 g
    • Volumn of clay: 1.25*100/3 ~ 40.417 mL ~ Measured: 40.417 mL
    • Volumn of HCl: 15 mL
    • Volumn of water: 55 - 40.417 - 15 = -0.417 mL
  • Repeat following this protocol
    • Higher stirring speed required
