Day 9


Crack pot

This time I mixed two different types of clay, majolica and brown.
This particular brown clay has 25 % of chamotte and the grain size is 0-0,2 mm.
Again, I overlaid the inside of the pot.
 This time with white clay.

I persisted in creating cracks while at the same time
 I had difficulty with forming the shape and I am not satisfied with this one.
It cracked a litte bit too much.
At one moment it almost fell apart complerely but I saved it!
This happens when you have problems with control
 and when you are not able to stop at the right moment.

UPDATE: Fired pot

The edge of the pot was to thick so it cracked at some points during 
drying. I then tore it completely so it can be equal.

Day 5

                                                                 

Crack bowl

Today I started working with pink clay.
 I wanted to do some bigger and thinner pinch pot.
With chamotte clay that it's not so difficult because chamotte gives your clay the strenght.
The higher the percentage of chamotte is and the bigger the grain size is, 
the stronger the clay will be.

This pink clay has 40 % of chamotte and the grain size is 0-0,5 mm.
At one point I added some white clay on the inside of the pot 
and I continued with stretching and shaping.
Eventually the cracks were formed and I liked the effect.
I continued with this process until the clay was too hard for stretching.
It cracked, but not much. 
This effect is something I could experiment with next time. 
Maybe I'll try to make bigger cracks on different clay.

UPDATE: Cracked during firing :(
