Hi there fellow potters of the world.

I'm fairly new to the world of ceramics....I've been doing this on and off
for about 12 years but just now getting into the thick of it.
I'm diong alot of raku and cone 6 firings.
Haveing bought my electric kiln from a phased out art program in the
Arlington , TX school District, I don't know exactly what cone I can
reach...so ^6 is as high as I've been attempting.

I've been trying to tame, harness, trap, ok.....just find (again) this
wonderful bright blood-red-wine-copper-lustery color from heaven that
appeared on the rim of a pot from my 4th raku firing for a while
now ....and....can't reproduce it...

So, to take a break from it, I've been trying to work on oxblood type glazes
for ^6 oxidation. So far I've only gotten so-so results....

I would really appreciate any help with accomplishing a color like in the
photo seen here: href="http://www2.netdoor.com/~swingred/images/oxblood.jpg"> OXBLOOD

(ByTheWay, you can back up to the "~swingred" directory and see my
fantastically beautiful baby girl)

The artist here is using, according to her website, a combination glaze of
Pete's Cranberry and a Japanese Oxblood...but in a ^10 (maybe reduction but
I don't think so..)

Will anyone share a nice comparable ^6 (Oxidation)Oxblood recipe with me?

Thanks,
Wesley Derrick

Dear Wesley,
It costs nothing to dream. And potters do alot of that when it comes to
reds at ^6ox. First, spend some time reading Iron Reds in the Archives,
particularly Paul Lewing's input. I am assuming it's Iron Reds and not
Chrome Reds you are after..., they are loads of fun too. Then start trying
lots of recipes - get a big slops bucket for the rejects. Be prepared to
fire down slowly, that means 50C/hour maximum and RR would say go even
slower so you get lots of crystal development.
I have had some luck with two glazes in particular:

BERRY RUST ^6ox (revision of Craig Martell's revision)
26 Silica
27 EPK
7 Nepheline Syenite
9 Bone Ash
13 Talc
18 F-3134
12% Red Iron Oxide (get the reddist looking one you can says Paul L.)
This glaze is a bright rust-red.

PERSIMMON ^6ox
46 Gerstley Borate
22.5 EPK
29.5 Flint
2 Soda Ash
11% Red Iron Oxide
This needs refiring to ^06-^04 to go deep red.
It tends to run so I glaze the bottom third of the pot in Berry Rust and the
top 2/3rds with Persimmon.
You could also try the famous Randy's Red. Lot's of people use it. I don't
have the recipe handy because I was so annoyed with my results that I lost
it.
One more "tip", iron reds do better, at least for me, on a clay body with
some iron in it.
Best regards,
Carol
PS and OT - I'm nearly back on this time zone after my US visit. Got to see
Toni Smith and her David Hendley mugs, Mayor Mel tea cups and dish, and
Gayle Bair soapdish. Had a fun visit with Sandy Miller - bought one of her
tea pots but had to leave it behind as the exhibition wasn't over. And
fleetingly met with Linda Goldstone. Clayarters are great fun. Narrowly
missed Wooster but the nights out at the CIM opera and Cleveland Symphony
Orchestra were thrilling too. I plan to try throwing to Stravinsky's Rite
of Spring - what a charged up 30 minutes that was in Severence Hall. Nan
Kitchen's packet of NCECA posters made it back home intact in my 100 lbs of
luggage. Thanks, Nan.
Off outside now to clean up after the 70 knot gale that blew through here
last night. Strange weather.
