Warming molds?

[LadyM]

I've always used tupperware for molds and was taught to put them in the oven on low to warm a bit (after greasing & lining) before pouring the soap in so they'd be closer to the temperature of the soap.

I'm looking to switch to a silicone loaf type mold, and I'm wondering if anyone warms these? Is it even necessary to warm with any plastic or silicone mold? Am I the only one that does this?

If there is a good reason to warm molds, it will likely be valid for all kinds of molds, wood, plastic or otherwise.

However, I never warmed anything.

Which brings me to the question: what does warming molds do for the soap ?

Supposedly it's so that the soap doesn't react to the temperature difference if the mold is colder in temperature that the soap temp.
I guess plastic (like tupperware) can conduct heat or cold based on weather/room temp differently that say wood.

I have never warmed a mold, have even poured out in the unheated garage in the winter. My molds are either wood or coated paperboard cream containers. I bring them into the house after I pour and put them in the basement, wrapped in towels/blankets and have not had any difference between those soaps and those I created in the warm kitchen.
