I want to make a note on the message that I posted previously:

I am using soda lime glass specifically for its low-melting properties.
Also, I've noticed that the email replies I've received include my posting
with an error in the depth of my channels.  Every number 5 that appears is
supposed to be a "micro" symbol.  That changes my channel depth from 105m
to 10microns.  Much better.  It would appear that I'm pursuing a new field
of dekafluidics!  Probably my fault since I used an ALT code to get the
symbol.  I am appreciating the comments I'm getting back.  Please keep them
coming!  :)
