"All good things...come by grace and grace comes by art and art does
not come easy." Norman MacLean, A River Runs Through It.
"We all share a creative goal with art. The goal is difficult; it is an
invitation to change the world. We can expect that our strength will be
spent, used up in a difficult struggle. We will arrive exhausted like a fly
in the evening of its only day of life.
But the "difficult' has never been a reason for not trying. And perhaps in
the end the only unforgivable sin is the refusal to try." Brother Thomas
Bezanson, Gifts from the Fire : The Porcelains of Brother Thomas.

Rafael has some interesting quotes, inspirational to say the least. I
like that. I would like to see a discussion on the importance of, "an
invitation to change the world!" To me, it is more of a quest of not
joining the wayward world, adding to it's strenght in going in a
direction that seems to be perverted. As artist, idealist, I struggle
with this world that seems to think building weapons is more worthwhile
than making things with clay, or creating other works of art, in a
variety of mediums, and expressions. I need to hear the encouraged words
of others, the experiences of others, as they struggle, as they have
struggled.
Our culture has become so much of a "spectator oriented culture," we
listen to others music, look at others paintings, watch others dance,
view others pots! Appreciation comes in doing these things, not just
observing, and leaving to go back to a world unfit for humans to grow,
and to be.
Do any of you know Andy Goldsworthy's work? It is obvious that since
early in his life, he has played, and he has had a belief in his play,
and the sculptures that he makes from nature are incredibly wholesome.
He also gets paid! Publishes his books of photographs of his work. He
has found a way.
I am trying to find my way. I play with poeple on the beaches, building
sculptures, that wash out to sea, but the memory never vanishes in the
minds of the participants. I conceptualize, and by doing so, I have
given much to communities, yet, I am not paid. Does the lack of pay make
me less? Sometimes I feel so! I am sure you all do. I need your
encouragement! Anyone? Everyone?

Isn't Blue Spruce the name of an evergreen tree? Perhaps it's not
meant to be "blue" but rather the sort of leaning toward blue
evergreen color?
Just a thought :-)

I had several reactions to the above post, not all of them encouraging. Like
Sherry, I thoroughly enjoyed Rafael's quotes. The exchange of money has
nothing to do with the value of an activity ( if you haven't already, check
out the film about Marilyn Waring ("Sex, Lies, and Global Economics"). But I
can't for the life of me see how constructing sculptures that wash out to sea
significantly changes the world except maybe you are creating very small
artificial reefs for aquatic life. Pottery for the potter is fun,
challenging, sometimes therapeutic. For the audience/users it is useful,
gratifying; for the very perceptive it may be thought provoking. But get
real. If you want to change the world there are far more effective means.

Clayarters :
Frank Helme sent me the correct recipe for Blue Spruce :
Blue Spruce ^ 6 Oxidation ( I fire with a ^ 7 in sitter)
Whiting 1000
Frit 3124 1250
Neph Sy 1250
Kaolin 750
Flint 750
Zircopax 500 ( I use Ultrox )
Copper Carb 100
Cobalt Carb 100
Rutile 250
The recipe published in ClayTimes left out the Cobalt Carb. I remixed and
retested and it is an improvement over the lime-green. A semi-gloss to
glossy texture. The color is a soft blue gray with some visual
texture/mottling. I also fire it in a ^ 7 Soda in reduction and its a more
intense blue.
Good luck!
