I have been thinking about the definition of 'grip'. The term can have many meanings and associations.

grip 1


n.
1.
a. tight hold; a firm grasp: drowning swimmer now safely in the grip of a lifeguard.
b. The pressure or strength of such a grasp: wrestler with an unmatched grip.
c. manner of grasping and holding: The crate afforded no comfortable grip.
2.
a. Intellectual hold; understanding: good grip on French history.
b. Ability to function properly or well; competence: getting a grip on the new technique.
c. Mental or emotional composure: lost his grip after he was fired.
3.
a. mechanical device that grasps and holds.
b. part, such as a handle, that is designed to be grasped and held.

4.       suitcase or valise.

5.        a. stagehand who helps in shifting scenery.

222 Grips for a Stone - Metamorphosis (40-47)

"stone is the only thing in nature that constantly dies" - Frances Ponge  
The solidity, reliability and impassiveness of stone is constant, yet it is continually changing, although at a greatly reduced rate compared with human life. Despite its solidity, it is worn down by atmospheric agents such as air and water, reducing large pieces of stones into pebbles, and then finally into fine particles of sand.

Because of this Ponge believes that stone is the only thing in nature that constantly dies (73). He then considers all forms of stone (rock, pebble, sand), all represent some stage of its evolution, exist simultaneously in the world. He relates this notion of connectedness as paradise, where all conception exists (74).

Stone is continually changing form, yet at the same time it remains true to its original composition of minerals. In some senses you could say that stone is an illusory force in nature, having the ability to continually morph itself over time. Once it is ground down into smaller particles it has the potential to be transformed into larger stones again through sedimentary processes, or melted under extreme heat in the form of lava.

Because of the vast difference in materiality between the unfired and the fired clay pieces, after much discussion and consideration I have started counting the before fire and after fire as different pieces in my exploration of 222 grips for a stone. 

Interestingly, the copper wire, which contains or grips the clay before being fired, acts as another grip after firing, as the melted copper sticks the ceramics together.

Earthenware Glaze Tests (low fire)

I have been experimenting with different low fire glazes. These glazes are for earthenware with a low firing temperature to cone 04. (1060 degrees Centigrade, or 1940 Fahrenheight)

This is partly because I have been working with found objects from the clay recycling room and these  shapes are usually made from earthenware, the clay utilised by the Introduction to Ceramics students in the studio.

I am interested in both glazes that run or form a drip, and surface texture. 

thickly applied Majolica (left) & Willing White (right) 

My first experiments were with thickly applied majolica and willing white. The test pieces were dipped 6 times and the glaze was about 1/2 centimetre thick. Whilst interesting, the results weren't quite what I was looking for.

Next, I experimented with double dipping of glazes, combining gloss finishes (such as power black) with textured finishes (Vardis blue).

Turquoise and Power black

It was also interesting to see how different glazes responded to being dipped first or second. Depending on this the resulting texture changed.

I then became interested in experimenting with layering different glazes combined with wrapping either copper or steel wire.
