How to route plexiglass?

I've been trying unsuccessfully to figure out how to route a channel in a piece of plexiglass for quite a while and now, having run out of ideas, I turn to the hive mind for help.
I've tried both a Dremel and a full-size router, but since they both spin at high RPMs (even at the Dremel's lowest setting), the plastic winds up melting and burring all over my bits as well as turning opaque due to the heat. My goal is to make the channel as translucent as possible, and I believe that I can put the plexiglass sheet in an oven after routing causing the plastic to smooth out and clear up any opaque areas caused by roughness. Can anyone recommend the proper combination of tool, bit, speed and technique to achieve my goal? Note that I am not wedded to plexiglass; I just need a very translucent material that I can carve channels into.

What this is for: I want to carve a single, continuous channel in the plexiglass, seal it to a glass top with silicone or similar substance such that the gap isn't noticeable. I'll need to get materials with approximately the same index of refraction, I'm sure. Once cured, I want to pump liquid (water, most likely, or perhaps mineral oil) through the path. Translucency is key, and the burring/melting problem I've been experiencing has made progress impossible.
