Firing times

17 May 2013 - 06:50 AM

Hello folks

I am interested in reducing the length of glaze firing for my pots. I was told, or rather, I always assumed, that you need to fire slowly to about 600ºC, then get up to temperature asap. I fire at 1255ºC, electric. (sorry not familiar with cone systems).


I have come across pottery bloggers who claim the need to fire slowly is a myth. After all, the industry fires tiles in 45 minutes from crude. And once, I had some pieces of porcelain fired by a kiln technician who set up the program to finish in 6 hours! and it worked.


I use an electric kiln and don't want to damage it by doing crazy firings.


Can I really do a firing cycle for porcelain in 6 hours? Pieces previously bisqued.


Any suggestions, much appreciated,

Alina

Glaze percentages

17 May 2013 - 06:34 AM

Hello there

I have this handwritten glaze recipe where the ingredients are correct, but the percentages don't seem to add up to 100 for the main body. It is possible i made a mistake when I jotted them down. I don't have time to test, can anyone suggest what I could do to fix it?Does it need fixing or is it possible it's ok the way it is? Shall I use less dolomite?Like 12%?

Sodium Feldspar 85%
Dolomite 15%
Bentonite 3%
Add:
Rutile 6%
Cobalt 0.4&


Any help, much appreciated

Glossy white glaze wanted

03 April 2013 - 08:52 AM

Dear potters,

Help, please: I need a recipe for a (creamy) white glossy glaze. All I seem to come accross in the books I have is, at best, satin, or dry, and not glossy.


I work in stoneware and porcelain (oxidation, anything between 1240ºC - 1300ºC, or 2264ºF - 2372ºF, (not that familiar with cones - cone 6, minimum?).

I am based in Europe, so I can't have certain ingredients (US Ferro frits, for instance).

I can buy locally the usual culprits: kaolin, feldspars, dolomite, ball clay, nepheline syenite, whiting, silica, quartz, oxides, that sort of thing.

Anyone care to share?(:-)

It would be very much appreciated.

How do I write on clay?

20 March 2013 - 03:30 PM

I would like to make a wall plaque in porcelain with a quote on in. Is there some obvious, simple way to write on porcelain? I have considered alphabet spaghetti, but can´t see how I´m going to get the "ink" in the grooves without smearing it everywhere else.


I lam looking for "printing" on clay that is crisp and clear.

Any suggestions - much appreciated.
