This is natural and will

This is natural and will increase with further firings of the piece.  The irridised surface is a thin coating of metal that has different expansion and contraction characteristics than glass does.  So yes, everyone experiences this.

I have no idea what a low fire irridised surface may be.  Maybe it is the kind used by Spectrum art glass that fires off at lower temperatures, rather than the S96 irridised glasses.
