Here are some images of the mixing of the slips and glazes in preparation for the Raku firing.
I have kept a record of each surface outcome and effect.
The mixing of ingredients requires accurate weighing, then once mixed with water to a cream consistency the liquid must me filtered through 80 grid mesh to remove lumps. This can take around 30/40 mins for each slip or glaze. It is very important to wear mask and gloves as these chemicals are highly toxic and must be stored in air tight container.
I displayed my previous work next to the new work to have reference to the colour and texture I would be requiring for the new work. I experimented with two new glazes I bought from the I.C.F. in the summer and I also decided to try a red Raku glossy red glaze.
As I was painting and dipping each piece I wrote by the side of each piece the method, slip or glaze I used. This is highly important when referencing the pieces after firing. As these are all test pieces records need to be kept.
This is the set up
The work is placed into the kiln and gas is turned on, the heat needs to rise gradually as not to shock the clay.
I keep constant records of the timings next to the degrees Centigrade. The aim to reach 850.
I managed 4 firings, 3 breakages, extra pieces stuck to work and some unpredictable results. A fantastic fire!
Raku Firing 25.11.19.
This was my second firing and I had gained the confidence and practise to work the kiln myself. The three loading’s of the kiln went much better than last time and I had no breakages or mishaps.
Due to be keeping a record of times and settings last fire, I didn’t require the meter and each piece of work was fired enough.
I had Roy come and take some SLR photographs and Tom came and filmed the second firing. Both of which I have not seen yet, however I will use to document this work once they are developed and edited.
