Tests results

Finally, after 2 long weeks of waiting our kilns were opened and my tests have seen the day light for the first time:)

On the test tiles glazes look nice and more or less up to my expectations... BUT... the very unusual results can be seen on a bigger piece that was decorated with black glaze and black body stain... My glazes turned out BLUE in places instead of transparent gray and white over black background!!! :D

Well that's what you get when you trust commercial colours I guess. It turns out that cobalt oxide (used as one of ingredients of this particular body stains) decided to show up in places.
Normally I like blue but this time it's out of place and the shade is too dark for this project.
I'm slightly disappointed with my matt and glossy tests as well. They are nice glazes but again not pure enough for this batch of work. The matt glaze has shiny satin finish and pink flash when thick (the flash could be cosed by other glaze that was standing very close in the kiln to my tests)
The glossy is very nice with little baby blue/ white clusters when thick.

It looks like I will have to finish being adventures and get back to my old glaze book or pull another trick out of my sleeve and make everything shiny...
I better go and look for nice matt glaze...

Naked Raku

In the end of January I have attended a Naked Raku workshop in Thomastown organised by  Ceramics Ireland . I already was familiar with both Raku and Naked Raku but wanted to extend my knowledge in this field. Naked Raku is a firing technique in which the pot is masked with the slip and then glazed and fired @ 1000 C then the kiln is opened and pots are transferred to the reduction chamber filled with sawdust, and covered to accommodate the reduction process. The difference between the Raku and Naked Raku is that in the second process the glaze is pealed off after firing and the pot unglazed- Naked. It all seems quite confusing and a bit complicated but in fact it is very simple, fast and effective way of decorating ceramics. The only disadvantage is that the pot is porous and can be use only as decoration as it is not food safe. With time the smoke marks can get lighter which can be slowed down by applying oil or floor polish paste on pots. ...
