How to make a PVA solution?
Conventional Method
Heat 1 liter of tap water to 88–90 °C (194 °F) or just under the boiling point of water. Once the water is heated, lightly sprinkle the polyvinyl alcohol into the water while stirring continuously (a magnetic stirrer/hot plate works well to heat and stir the solution).
