Devit sprays

[Stephen Richard]

It’s normal to apply the devit solution ( whatever it is – propriotary, borax, clear powder or frit, or something abrasive like sandblasting) while the piece is still flat.  Doing it in the mould is inconsistent, and reduces the probable life of your mould. From your description I have no idea of what it might be.  You could try an abrasive solution – sandblasting or abrading with fine wet and dry sandpaper and then fire polishing again.
