Post 27 Finished pot

The glaze firing went well and Pot 19 is now done. It featured in Post 24 when bone dry and now here it is all glazed up.

The finish is a nice flat satin, blue going green.

 
Final dimensions are 422 x 312 x 81. Dimensionally it has come out really well, I'm very happy with it.

Just for fun to illustrate how much fired clay shrinks, here is a picture of the finished pot sitting in the mould it came from. This is a bit hard to believe when you look at it but it comes to 55mm. Bear in mind that most of this shrinkage occurs in the glaze firing. So as the glaze melts and the clay vitrifies the whole thing contracts, sliding across the kiln shelf - love to have a time lapse series of that.
 

Post 26 First new oval pot

This is the first pot I've turned out of the new oval mould I made recently. This is air dried only - having taken a good three weeks bagged. If you look back to Posts 21 and 22 you can see that it has turned out as expected and a very good likeness to the shape I was after. It just has to stay that way through bisque and glaze firing.

 Final dried dimensions are 440 x 320 x x97.   What do you think?

I need to get in and make some more now before I get any where near ready to glaze it.

I've been spending my time getting ready for another trial of a series of glazes. My Seger model has been very useful to adapt recipes to available materials in a much more informed way. The trial has about 4 or 5 base glazes each with 2 or 3 subtle variations to test changes in surface finish, further superimposed with a number of different colourant combinations. On top of that there are a number of one-offs which look interesting and fun to test. So I have ended up with about 100 test tiles to fire - that is quite an enterprise to mix and apply let alone make all the test tiles to start with. It's taken up most of my potting time over the last couple of weeks.

With all those test tiles I have only room in the kiln for one pot to be glaze fired, but the testing remains a priority right now.  I'm planning on firing up the kiln tomorrow and so over the next week should have some glaze test results and a finished pot to share.

Post 25 Chinese Elm Group

We are deep in the middle of winter here in Australia at the moment. In fact the max today was only 19C so it was a really cold day!!! Yes ok that's true - down 'south' it really does get cold. Hard to believe then that the deciduous trees we grow here really think they need to drop their leaves. Mind you I do have a few that sometimes go right through to spring without doing so and so need a little 'help'.
I put this one up earlier in the season and wanted to show it again bare. As you see I've dressed it up with some moss to make a pretty picture.
Apart for the tree let's look at the pot.

 

Now firstly it's not one of mine, that is I didn't make it. I can't remember when I bought it even, but it was a long time ago and it wasn't expensive. The pot doesn't demand attention and has a subtle off white colour with a pleasing diffusion in that colour. Around the rim there is a depth of colour reminicient of patination. When you get close you can see that the glaze is a 'crackle' glaze - formulated especially to crack - and there are a number of mineral inclusions which have bled as the glaze fused. The whole effect is a clever contrivance to give the impression of age. Even a little glaze carryover onto the feet suggests making at a less precise time than now. Suffice to say that these things haven't happened by accident and are the result of careful planning and deep knowledge of the materials applied. I'd be proud to create the same illusion.
