Seger cones, old tech in the “digital age”

Glazing bisqueware (clay object after the first firing) is very different from painting an object. You can’t see which texture and color (effects) you are applying during glazing. Applying different glazes, slips or oxide washes, the ceramicist must compose the colors in his or her mind.

In doing so, he/she must take into account that overlaps of glazes do not always lead to a mixed color, the thickness of the glaze effects color and/or texture and the application method (spraying, pouring over, brushing, etc.) may or may not lead to desired effects. Just to name a few variables. So the disappointment is great when the thought experiment does not match the final result.

I haven’t even mentioned one of the most important “wildcards”: the glaze firing. To tame this beast, many digital tools have been developed over the past 20 years. The most important of course is the (computerized) kiln control. however, this does not make the Seger cones superfluous.

In contact with the past

Sometimes  you feel suddenly connected to the past. You see an old photo, you whistle a song your grandfather always whistled or … you make ceramic birds.

Ancient-Iranian-Cermamics
Ancient Iranian Ceramics, Sackler Gallery

A few months ago I read an article in Ceramics Monthly about the exhibition “Ancient Iranian Ceramics“. It was a small exhibition of ceramics from about 3,000 years ago (!).  These ceramic objects where excavated in the area south of the Caspian Sea in what is now modern Iran.

The small installation showed a number of treasures from the collection of the Sackler Gallery. It celebrates the talents of the ancient Iranian potters and shows the high quality of their works.

Art about or for man?

If I may believe the selection of the weekly dutch art program “Avro’s kunstuur“, most of the art has the human being as subject.

Whether it is video art of Priscila Fernandes or the photos of Vivianne Sassen; man is central. And if it is not the human itself, then it is its effect on the planet, as manifested in the architecture or the landscape.

ceramic art, is clay or man the inspiration?Does this bother me? Of course not, everyone is free to have his own muse. But where most artists use these goddesses as a reflection of humanity as inspiration, I think for the ceramist only one of the nine muse “Urania” (the muse of astronomy, forerunner of all science), is a source for his or her work.

Not for nothing ceramics is known as the most scientific of the arts.

In ceramics is, after all, the control of the material of the utmost importance, and science has a great influence on the development of this art form.

Ash, a bit of winter in your glaze

Summer has just begun, so now it’s time to use the last bits of winter …. in my ash glazes.

Last year I had a conversation with a befriended couple, about wood turning (friend ) and ceramics (me). A wood turner often uses the same design language as a potter and I think both have a great passion for the art of the profession, so for us, there are always plenty of things to talk about. Such as “who turns wood, will perish in wood shavings“. 

But the raku ceramic artist is happy to help a wood turner with this problem, as smothering the raku pots happens after all often in a sawdust bucket. You understand, I could get a lot of  sawdust from my friend ….. but apart from that I do not have enough room for storing so much sawdust, I fire raku too little to have use for it

However I would like to have the ash (also needs a lot less space, only 10 to 20 grams remains from about 1 kilo of wood). And as you will guess, my friend could also provide me with this, not because he is a wood turner, but because they keep their cosy houseboat warm in winter with a wood stove.

So, after the winter months, I could pick up a few kilo of ashes, but what to do now?

Crystal formation in glaze slop

For some time I discovered crystals in some glazes that I kept in my (enclosed) glaze buckets. These are self-designed glazes of kaolin, quartz, frits, wollastonite, etc. Mixed with water and peptapon.

Some glazes had small crystals (felt a bit like sand), but some glazes developed large amounts of crystals. In some cases as large as a five euro cent (see photo). These crystals made it impossible to glaze (because glaze spray got plugged), so I started to look for a solution.

Every beginning is difficult

Starting a ceramics blog is as difficult as your first glaze test; you have no idea how to do it, but if you do not try, you surely will not succeed…
