Hi,
Are there any engobes that have a satin sheen by nature, rather than the
dull unsmooth matt surface needing glaze to cover? Any that act as a glaze,
eg, hold water? Or must I use a tera sig, burnish, and forget the
functional possibility?

Thanks again,
Centa

Centa,

I once heard that Susan Peterson uses 50% slip and 50% glaze mixture to glaze
her once fired pieces. These pieces had the satin sheen you seem to be
looking for. I tried this myself and had some interesting results, but as I
did not want to once fire my work I discontinued these experiments. I tried
25% slip and 75% glaze and the 50% mixture applied to leather hard clay. Some
of the results were actually metallic but none were as nice as Susan's smooth
creamy results but maybe I needed to experiment a little more.
This maybe something you could experiment with.


Good Luck,

Jenny Dubats

Jennifer,
Interesting that you should mention Susan Peterson. I don't know her work
but I am reading her book, "The Craft and Art of Clay." I most highly
recommend this book to those of us beginners who are now ready to read up
on the subject. Incredibly filled with practical application stuff. One
part that is just a bit unclear (to put it mildly), probably because it's
simply over my head at this point, is the presentation of "fusion buttons"
and 50/50 blends of different glaze materials; it is beyond me how to
interpret the pictures of the little dipped tiles. But it is an amazing
overall resource for someone just starting out and wanting to establish a
foundation from which to work in one's own studio. I imagine it might also
be of benefit to those who are more skilled as well. Thanks to Steve at
Potter's Shop for the recommendation.

Thanks,
Centa

Centa,

I do like that book. I have it and refer back to it often for all sorts of
info. It is a good one to own. The testing and fusion buttons are better
seen and the process of testing materials and blends are explained in Greg
Daly's Book "Glazes and glaze technique." He talks about learning and
understanding glaze materials as a journey. He gives you steps to go through
to develop glazes and understand your materials. Lots of great pictures of
glaze application. Of course, time being short for me I have not gone through
all the steps but the book has a lot of pictures that give you an idea of how
things work.
This book is worth owning also.
I do have to apologize the potter I meant to mention was Susan Stephenson. I
keep getting Peterson/Stephenson mixed up. I was at a throwing workshop and
someone had a piece of hers and the englobes were smooth, opaque and slightly
glossy. Very nice looking. Hope you find (or develop!) the englobe you are
looking for.

Sincerely,

Dear Jenny:

I would like to try this technique /engobe/terra sig and would like to
request if you know what cone Susan Peterson was firing to. I have also
done some testing with engobe but never had anything specific to my
likeing. I would like to do some testing with once fire ware and if you
know what cone Susan was firing to this would be helpful for me. Thanks.
I fire to cone 9 10 noramally
reduction/gas kiln
