I have a batch of Vince's super refined terra sig that has been
mixed up and is working quite well (thank you Vince). I'm know thinking
about using some lusters at a very low temp over the terra sig to
basically see what I can get. I have never worked with lusters so I
don't know much about them. My question is, do ya'll think this will
work? Do you have any recommendations/thoughts on how to go about
application of the lusters if you do (spraying, dipping, burshing?).
Also, how unstable are lusters? I have waxed and buffed the TS for a
nice smooth satin finish. Would this work with the lusters or possibly
obscure things? I'm happy to experiment here, but don't believe in
re-inventing the wheel either. Any thougths or suggestions are greatly
appreciated.
Thank you for any and all help

I've used lusters on bare clay with nice results. Palladium on bare
clay looks just like aluminum. Sounds like an experiment worth trying.

Not so fast, Snail. Remember that the ancient terra sigillata process was
rediscovered in the 19th century by German ceramic chemist Henrich Schumann
when he was searching for a vitreous coating for ceramic sanitary sewer
pipe. A proprerly prepared and polished terra sig finish is not truly
vitreous, but it is damn near as impermeable, and I think that the idea of
applying a luster over this surface is very interesting. This could work!

Craig, I have done this and then smoked the pots after. It was very
exciting and I plan on doing it again. The reason I didn't develop it =
more
was that the property owner frowned on having any flames in the yard. =20
I guess you could brush or spray if you want to, but being very =
expensive, I
would not spray. I used a rubber dabber that you can find in an =
art/craft
store, or make your own with scrunched up sponges on a stick. I did a =
lot
of blending that way, used templates for designs, and other experiments.
I think you will find this very exciting. Hope you will post photos =
when
you get some results.

Don,
I use a lot of luster. All the lusters I've used call for 018. Also,
lusters take on the surface they are applied to: shiny glaze for
shiny luster, matt glaze for matt luster. It also looks best on glaze
instead of terra sig. What you are seeing is twofold; the luster
isn't hot enough, and the surface isn't optimal. Try them on a
shinier glaze at 018 for best results.
Regards,
Lynn

Sorry, I couldn't resist this one.
I just happened to have some shards of a pot made at Vince's
Ancient Clay workshop some years ago. It has his Redart
terra sig on it. I knew that pot would come in handy some day
after the cat knocked it down.
I just happened to have some tiny bottles of lusters.
One is labeled Metallic Gold China Paint; another is
MedMar Amber Pearl; the third is Duncan OG802 White Gold.
I brushed a sample of each on a shard and fired it to ^022
in the test kiln this afternoon. Results can be seen at:
http://dongoodrichpottery.com/tslusters1.jpg
Although the lighting is not the best, the result is clear.
The white gold came out shiny just like it's supposed to.
Amber Pearl is hardly visible. On different clay it might be.
The china paint is a dull gold, and rubs off easily.
None of them seem to be very durable surfaces. Higher firing
might help, but 022 is the only cone I have on hand that's
anywhere near the recommended temp for these.
Hope this helps.
