Stainless steel vitrigraph pots are durable replacements
for ceramic pots that do not last many - if more than one - firings. But cleaning is
not straight forward. Most recommendations seem to concentrate on cleaning by
banging the metal to break the glass away from the sides and bottom. This seems more brutal and noisier than
necessary. It will eventually dent the metal and possibly become unusable.

An alternative is to line the sides with 1mm or 2mm fibre
paper. Paper of this thickness has
enough fibres that the paper will stick together and not contaminate the
pull. It will still protect the metal from
glass sticking At the conclusion of the firing and after the cool down, you can
remove the fibre paper and have clean sides.

It is possible to put a piece of fibre paper on bottom with
a hole in it to match the pot’s hole.
There is a slight risk of drawing fibres into the pull, although I have
not experienced it yet.
This method also works with ceramic pots.
