Subject: Copper Metallic Raku
I am re-submitting as I assume my original disappeared into some unknown.
We are doing a sale in two weeks and am concerned about informing
of the possible fading of the bright metallic copper glazes. Will the
coppers fade as well? I use most all of mine as planters as the Raku
breathes well and my plants thrive beautifully .... and if they
time, I can simply throw some more. Maybe I should add a disclaimer
for both fading and non-water proofed?
I will appreciate any advice.

having produced raku ware for the past 17 years, i can honestly say that
what you pull from that blazing fire does not always maintain that initial
appearance....due to the factors of the vessel ultimately residing in an
oxidation atmosphere, (our planet) the long term affects are much the same
as when you introduce too much oxygen into your reduction chamber whilst
you are in the reduction process...HOWEVER, i have taken note, that over
the years, pots that were previously very laden with heavy copper surfaces,
can fade to a lovely painterly surface, often displaying character that can
be more attractive than your initial firing....i feel that the raku process
lends itself well to the idea of an everchanging pot....examine your pieces
every few months to see the subtle changes and delight in what i consider to
be a living glaze....

I think that it would be fair and wise to inform potential customers of
the raku-ware's inability to hold water for any length of time and that
glazes may dull or fade as well. I don't know too many people who are
willing to buy under these circumstances and recommend that perhaps you
spray the exterior with an acrylic sealant to maintain glaze integrity and
suggest that your buyer consider use some sort of liner (i.e. a smaller
plastic or terra cotta pot) inside a larger raku piece to protect it from
disintegration....at any rate...let them know whats up...as potters,
artists I believe its our responsibility.
