Salt and water dough, uncooked. This kind of dough is ideal for making decorations that you might wish to detail further and keep. Mix thoroughly 1/4 cup of salt, 1/4 cup of water, and 1 cup of flour. Work into a very smooth dough using a wooden spoon and then your hands.Use biscuit cutters and a table knife to cut out the shapes you want. The dough will harden over 24 hours, after which it can be painted or covered with glitter.eat 1 cup of flour and 2 cups of water gently in a pan over a low heat with constant stirring until thickened. Allow to cool. Mix in drops of food colouring until you get the desired colour. You can scale up this recipe, dividing it into batches before adding different colours to each.
The science behind how salt works lies in something known as the freezing point. Salt has a lower freezing point than water, which is why salt water does not freeze as quickly as pure water. This lower freezing point is what enables salt to melt ice and snow. When you spread salt on ice, it acts almost like a molecular sponge. It draws some of the frozen water molecules to it and, because of its lower freezing point, breaks the molecular bonds between them. These broken molecular bonds cause the ice to melt, creating a brine that encourages further melting.
Brines have the same melting characteristics of solid rock salt, but since it is applied in liquid form, the salt can begin to work immediately. The brines are also more effective in lower temperatures. The use of brines is known as anti-icing or pre-wetting measures. Anti-icing can be accomplished by using traditional salt brine (usually a 23 percent salt solution, derived from rock salt) and applying to roadways in preparation for snow and ice.
