Posted 25 May 2013More "industrial" type references for you:
Posted 25 May 2013Not doing Davis Carbon Trap (I actually don't care for that look very much)
Yoda! Yes. Yoda is a little better looking but still perfect!
Ahhh, carbon trap is not your destiny I can see, eh. Soluble soda sources in the glaze recipe diminish you should. Early strong reduction in the kiln want you should not. To the Dark Side those paths lead.
To the easy path of Soda Ash do not give in. Soda ash leads to solubility. Solubility leads to water evaporation ionic migration. Water evaporation ionic migration leads to early melting glaze surfaces. Early melting glaze surfaces leads to gas impermeability.
May the Feldspar be with you......always.

Posted 24 May 2013Rather than discount your work ... or have "sales"....... all of which devalue your products in the consumer's eye (why buy full retail....... the true value is something less than that) ........ maybe make some small quickly produced items that you can ADD to the bag/ box when you deliver the order or piece at a show.
In Japan this is called "Sabisu".... "service".
It is a very pleasant surprise for the customer to get something MORE from you than what they paid for. It is very erffective. And keeps your prices as THE prices for your work. The nature of the "service" piece can vary with the overall sale price of the original item...... as you see fit. It could even be a quite high price piece on a VERY high end purchase or from a serious good repeat customer.
Sales and discounts are for competing with the philosophy of Walmart and KMart.

Posted 24 May 2013Tim,
So what is the goal for the shinos? Carbon trap? One just fire color? Carbon trap to the max (black shino).... or more subtle mixtures of color and blackness?
For heavy carbon trap.... you almost can't reduce too low. (Don't take that literally. ) For average carbon trapping I use about cone 010 as the starting point. With MY shino formulation if I get to about cone 05..... carbon trapping is not really possible anymore..... outer glaze surface is sealed over with highly soda fluxed glass.
Watch tenmokus in long duration firings.... they can run.
In my noborigama I have the luxury of firing different chambers in different atmospheres and to different end point cones... so I use all sorts of firing cycles. Some Japanese style shino I do has very, very light reduction at all... like much Japanese shino ware, the glaze is quite white with light red firecolor on the thin spots.
I don't think of "body reduction" and "glaze reduction".... it is all one continuum. In a wood kiln you are cycling from pretty strong reduction to pretty strong oxidiation on most every stoke anyway once you are at a certain temperature. I look at HOW HEAVY it swings to reduction on the stokes rather than holding it in a steady state of reduction constantly. The length of those reduscion periods also varies relative to the oxidation periods as the stoking rate.volume goes up on a single stoke.
As to downfiring.... on my last one or two chambers I often use the Bizen-style youhen charcoal technique.... and that REALLY retards the cooling and holds it in HEAVY reduction until the wares are not really reactive anymore.
Posted 24 May 2013Jim,
I'm very interested to hear the results.
