The color temperature of daylight is close to 4300K, which is why we as human beings that see best during the daylight are able to see more vividly with a 4300K HID kit compared to 2300K from halogen bulbs. The light output from a 35W 4300K HID Xenon lamp is about 300% more visible light than a 55W halogen bulb.
Magma originates either from rising plumes of heat at hot spots in the Earth's mantle, where decompression melting takes place as the hot rock nears the surface; or, it originates in the mantle from subduction of oceanic crust, where cold, wet rock speeds melting of the subducting rock and it rises toward the surface.
If you start melting this rock, however, the magma that is generated will be highly concentrated in the things that melt more easily, namely the ice (now water) and butter. There will be a little bit of molten sugar in your magma, but not much, most of it will still be crystalline. The most common type of magma produced is basalt (the stuff that is erupted at mid-ocean ridges to make up the ocean floors, as well as the stuff that is erupted in Hawai'i).
