Back From Catalunya

26 February 2014 - 04:10 PM

Got back from Catalunya. Barcelona was awesome, like always. I spent a nice week in the studio called El Torn Barcelona (http://www.eltornbarcelona.com).
Martin Loew is a really cool guy to work with. Learned a lot. Thank you.

I can not recall who recommended me El Torn here but thank you for the tip. :)

Building A Large Thin Objects, Is It Better To Use Low-, Mid- Or Hig Temp. Clay?

17 January 2014 - 01:03 PM

Lets say you have to slipcast relatively large bowls. Top diameter (widest) is about 45 cm (18.3") and hight is about the same.
Final walls (after firing) can not be thicker than 6 mm and the shape is relatively complicated (not just a nice upside-down arch).
Q: Is it better to use low, mid or high fire clay?
Or lets ask this way: will low fire white clay warp less than a mid- or high temp white clay or half porcelain.

Pieces will be glazed with what ever the clay temp requires (forget the glaze for now)

Looking For A Gray Glaze (Picture Included)

22 November 2013 - 12:47 PM

I am looking for a good "dark" grey glaze I can fire in oxidation on light stoneware clay. We wire around 1249C (cone 9)

This the tone (or shade) of grey I am looking for (forget it's b&w image):

Do you have any good recipes?


I am thinking about experimenting with white satin glaze I have and adding some black stain I got (Co-Fe-Cr). Am I even on the right track?

Converting Reduction Temmoku To Oxidation Firing

18 November 2013 - 06:09 AM

We fire our stuff around cone 9+ and we have a electric kiln.

Here is a Temmoku glaze recipe for reduction atmosphere:

Mark's temmoku

Custer Feldspar	45
Silica	27
Whitining	17
Kaolin	11
Red Iron Oxide	10

(sp gr 150)

Can this be converted for oxidation atmosphere? How?

Reason I like this is it's almost black. I like deep dark/black shiny temmoku. Red thin brown is not what I am looking for :)

Epa Bans Most Wood-Burning Stoves - Will This Affect Wood Fired Kilns Too?

EPA Bans Most Wood-Burning Stoves

I am not is US but overacting civil servants and their hysteria fueled crazy ideas have bad habit crossing long distances, even oceans.
Come to think of it, similar madness is happening in some parts of EU too.
