Here I would make a distinction between "superior" technology and magic. I think that most of these things are not regarded as magical by the elves any more than we regard the internet as magical. However Lembas and Niruvor are versions of things originally made in Valinor so it is possible that Galadriel's power was a factor in their production and it is likely she learn't much from Melian. However Galadriel clearly has power in her own right, mighty among the firstborn (cf Gandalf's reference to Glorfindel "Could he storm the road to the fire by the power that is within him?") but is inherent power the same as magic? Clearly there is a form of spell craft available in Middle Earth as can be sen by Gandalf's behaviour at the doors of Moria - and some of it is available to beings of lesser power than Galadriel (eg THranduil).

Interesting questions are raised by the Mirror of Galadriel - this may be a projection of "foresight" but it is not clear whether Galadriel would regard it as magic- though she knows that is how it will seem to the hobbits. Also the Phial - is it a "skill" or a spell that allows her to trap light in a phial of water - the closest thing to matching the capturing of the light of the trees in the Silmarils? And is the power that it gives a transmission of Galadriel's power or a distant protection given by the Valar who will not involve themselves more directly? The light of the stars is the gift of Elbereth and her name, acts as a "spell" for deflecting evil at several points in the story. I will be interested to hear what others think.
