Is this like Make Magic?

It's the term I made up to refer to the twins ability to create objects and weaponry out of solar and lunar light. I'm fairly certain in the anime it is called Mold Magic. Grey had Ice Mold Magic, that guy from the Grand Magic Games had Memory Mold Magic. Though I could see where that comes from as whenever any of them create something they say "ICE MAKE SWORD!" etc.
