Melting point of silicone

Always melt chocolate slowly, at a low temperature. The melting point of chocolate is between 86 degrees F. (30 degrees C.) and 90 degrees F. (32 degrees C.), lower than body temperature. Using high heat is very risky and the most common cause of grainy and/or lumpy chocolate. Chocolate melts better and faster when using lower temperatures. This generally leads to low melting points for covalent solids, and high melting points for ionic solids. For example, the molecule carbon tetrachloride is a non-polar covalent molecule, CCl 4. It's melting point is -23°C. By contrast, the ionic solid NaCl has a melting point of 800°C. It has a very high melting point as the ionic bond is very strong between them. More force is required to break down. Silicon dioxide is a giant covalent structure. It also has the highest melting point because the covalent bonds between them is the strongest. if you are satisfied so mark as brainlist please Product Description.
