Re: Dissolve epoxy glass but not copper?

Fire is good.

This is not easy.  There is one solvent that dissolves epoxy,  I forget its
name, not common though.

Then you get the glass fibres everywhere.

This may not be the best approach.

You could try photoetching copper tape stuck on a simple plastic substrate.
3M make copper tape 4" wide by as long as you want.  his would give you the
capability to select a plastic which you can dissolve.
