My ceramic pieces - plate disaster - part 2

I give up. This mould obviously will not work. No chance in hell. It went pancake again, even though this time I made it from crank and made sure a layer is really thick. OK, I admit that my "thick" is often not thick enough, but still... a pancake?! To top that the oxides went brown... and why did they went brown?... because I have used matt instead of gloss. I am the only one in a studio that uses matt, so only my dandelion test showed that oxide with matt just do not work. So here it is, brown tacky colour instead of strong greens and blues. Great! Oh joy of ceramics!

My ceramic pieces - Umbrella stand, take 2

I had decided that my first umbrella stand was too wide and too small, so I have to make a new one. I am quite happy with it, although next time I would spend more time smoothing a crank (memo to me; wet rubber kidney works like a charm!). I have managed to smooth most of the bumps and make it quite symmetrical - and trust me, this is a huge achievement for me; for some reason me and symmetry do not go together. The tool I used to shave off extra clay, I think is usually used by builders. It looks and works as grater. I absolutely love it, the only minus is it leaves a surface quite ... rustic for better word. Nice texture really, just not what I was looking for in this project. I was hoping a spraying with white slip would help the matters, but improvement wasn't great.


So far I did not really decorate my pieces, going for more of the shape, than a colour, but now I wanted something pink. After a bit more investigation into mixing glazes - oh blessed naivety! - I had to forfeit. I will definitely want to learn more about glazing and mixing glazes, but definitely not on raspberry pink. The amount of elements that had to be prepared from scratch is just frightening. And I haven't even asked if it was a reduction or oxidation, what temperatures should apply.

Luckily my test piece turned out almost as I wanted, so I've compromised. I have used chrome oxide on white slip and then sprayed it with white gloss glaze - I have to admit, I do not remember its proper name (memo to me - ask Stephen!). I would much rather go for the matt option, but matt does not work out... or rather turns everything to brown. The thickness of the chrome mixture has no true impact on an intensity of colour.


So here it is, looking great... so far. On a second test piece I made, I have noticed, that a white gloss, needs to be quite thick or chrome will turn brownish colour. I am going to cry, if it gets ruined!

Chicken coup with a lime twist

Call me bonkers, but after a last episode of 'It's Not Easy Being Green', I am contemplating having my own chickens... in a city. I know, ever so slightly mad. I haven't even mentioned anything to C or J and there of course is a matter of aesthetics; wouldn't like a chicken coup that would take half of mine already not so big garden. So until tonight the whole idea was rather ephemeral, but then came Eglu:


and I must say, the idea of keeping chicken in my back garden suddenly became insy wincy less bonkers. One can get Eglu from Omlet for £353 or with two chickens for £388

In search of pink raspberry glaze

I am a total novice when it comes to glazes. I use what is in a studio, but tend to go for whites most often. This time however, I am in desperate need for pink. I want it to be nice and warm, kind of raspberry or raspberry and cream.

Of course there is no pink glaze in a studio. None, there is no nice red either for that matter. I am saying of course, because I noticed lately, that with me and my projects somehow things never go nice and easy.

Anyway, so I am on a mission to find pink glaze and so far I have found:

Spinach Potage

My family loves this soup. Last time I've made it, a wee one had 5 mugs of it. Five! No idea where she puts it though :D The soup itself is very easy to do and quick.
  • 2 onions, sliced
  • 2 cloves of garlic, crushed
  • slash of oil
  • 1 litre of water
  • 2 veg stock cubes
  • 1 ts lime jiuce
  • 4 medium potatoes, peeled and diced
  • 250g fresh baby spinach
  • 1 cup milk
  1. In a saucepan heat up an oli and then add onions and garlic. Saute them for 3 minutes or until tender and translucent. Add potatoes and saute for further 5 minutes
  2. Add water, vegeterian stock cubes and lime juice. Cover, bring to boil and simmer 10 to15 minutes or until potatoes are ready. (You can speed up this process by adding already boiling water.)
  3. Add spinach and milk, bring it to boil and cook for further 2 minutes.
  4. Blend a soup until creamy and serve.

Ceramic Voyages - Teco

Teco Art Pottery was created by William D. Gates, the founder of The Terra Cotta Tile Works and tntroduced to the public at the begining of the last century. Butifuly architectual and fabulously practical epitomises the principals of the Arts and Crafts Movement;
"Have nohing in your house which you do not know to be usefull, or believe to be beautiful".

I love old pieces and a new ones. Strong, fresh, very expresive, with an emphasis on shape more than on a colour or decoration.
