Ice flowers.... These beautiful flowers are made by deep freezing water in silicone molds. They are very easy to make, but need very low temperature to retain the shape.
Here is the step-by-step instructable to make these ice flowers...
Step 1: Silicone Molds
Silicone is a rubber-like material, composed of silicone, carbon, hydrogen, and oxygen. Silicone rubbers are mostly two-part polymers, the base and an activator. When these two components are mixed together in proper ratio and poured over a solid object, the compound solidifies during the curing period and forms a flexible mold for that object.
Silicone rubber is generally non-reactive, stable, and resistant to extreme environments. they can withstand temperatures from -55 °C to +300 °C while still maintaining its properties. Unlike metal or plastic molds, silicone molds are flexible and very easy to take out the molded object from them without any damage to the shape.
Let us see how we can make our own silicone molds at home in the next step.
