    I have had the opposite experience. I experimented with using
    titanium as a base for plique a jour by setting the pierced silver
    piece directly on the Ti then filling with enamel. After firing the
    piece it was easily separated from the TI with little to no effort.
    Normally I put a piece of mica under the pierced piece. The results
    were very good with no mica to stone off. There was no curl or
    upward pressure from the expanding mica. The only drawback to this
    technique is the you have to stone off the titanium oxide layer. The
    only advantage I found was that I did not have to use wire to keep
    the piece flat.
