One example of something we put in a freezer that doesn't get cold but melts from cold and gets frozen from the heat is "candle wax."
When you place a candle in the freezer, the wax does not become cold like water or other liquids. Instead, it retains its solid state, albeit becoming a bit more brittle. However, when you take the frozen candle out of the freezer and expose it to heat, such as by lighting the wick, the wax starts to melt and turn into a liquid. As the candle burns and the melted wax drips down, it eventually cools and solidifies again, this time as it comes into contact with the cooler air.
So, freezing a candle does not make it cold to the touch, but rather, it alters its properties, making it more susceptible to melting when exposed to heat.
