failure rates and learning curves


To answer Ms Moon's question, what do I do with the ones that don't pass muster?

Well, I don't finish them for one thing. They usually go on a shelf somewhere until they get put in a box and eventually thrown away. This one will go next to another oleander failure, one that was over-fired. The last time we did one of these we had to do it twice.

This is how the turquoise bowl was supposed to turn out.


If it's a casting defect and I think I can salvage it with a little creative cold work, I'll make the effort but mostly a bad cast can't be remedied. This piece cast well but the colors didn't work out. That in itself, while disappointing, is not an immediate reason for rejection. I've sold many a small bowl whose colors didn't come out the way I envisioned. But on this one, the colors were just too extreme on the one hand, the blue, and the white did not show up adequately and was pixelated to boot and when illuminated from above nearly disappears altogether.

Failure is always a possibility with this technique and now that we are only doing one of a kind pieces, that danger is a little more present. When we were doing the small bowls, a form we had done over and over, a couple hundred times, we got so good at them that our failure rate was almost non-existent. But when we switched to a taller form, I stopped trying the 6" tall vase because after the first two that came out perfect, we couldn't seem to get one that didn't need extensive cold work. The last one we made was so perfectly cast except for the top inch and a half which was a total ruin that it made me cry.

And while most of the failures come from bad casts...over-fired and full of pits, under-fired and granular, mold cracking during firing, not holding at the casting temperature long enough...other failures come from how the mold was filled...too much glass overall, not enough glass, not enough of a color or too much of a color, mixing colors together that react badly with each other, putting a dark color behind a light color. And then there is always the mold itself which can be weak and full of bubbles if not made properly.

I know that every time I try a new form, like the boxes, I'll have a few failures so I try to ease into it. I'm trying to do things that are simpler in some ways...no more two and three part molds. Well, two part molds but easier two part molds. These days I'm doing work that can be cast in open face molds, the easiest of all.

This technique is the most difficult, time consuming, detail oriented, and sometimes frustrating thing I have ever done, and infinitely rewarding when it all works out right. It's a good thing there were two of us while we were working on our learning curve because there were many times when one of us was ready to give up. Fortunately, neither of us were ever ready to give up at the same time.

  1. as true artists, you are perfectionists and most critical of your own work. but that's what makes your pieces ultra-special. :)

  2. You could always take the "mistakes" and make "yard art". You know, bird feeders and such. There is actually a market for that ..........

  3. Keep it up because that bowl is stunning and beautiful. I have never seen anything like that. I now have a more critical eye.

  4. Ooh - I like the yard art idea. Our sparrows would drink out of a lovely bowl like that :)

  5. That bowl is luminous, and worth all of the previous frustrations. It's great that you work so well as a team, because this is very difficult to do and pretty important to have the support of another expert.

  6. Lovely finished piece. A lot of work to get perfect, but hopefully it doesn't keep you awake nights.

  7. Failing makes success so much sweeter.

  8. So interesting hearing all the things that could/sometimes do go astray in the making of a piece. I know so well all those baited breath moments, and knowing you can't take shortcuts, though sometimes do. Understand the crying too, but if you know where it went wrong it is sort of ok. Amazing, after all that, how simply beautiful the 'perfect' ones are!

  9. To me, they're all lovely. I think the work you do is just amazing.

  10. And there’s me thinking you are artists who never fail.

    Sorry, that was a joke in bad taste. Like all true artists you are your own meanest critics. I love the work you show and I am sure there is a way of selling what would be called ‘seconds’ here, unless you think inferior pieces might hurt your reputation.

  11. I had this post open on the monitor this weekend and my husband asked, "What's that?" He liked it:) Then he asked if you sell your work and I told him you present at shows in Texas. You have another fan!

I opened my big mouth, now it's your turn.
