There are many variety's of clay, with porcelain being the purest. the variation is due to the materials that break down to form the raw clay. we experimented using clay to produce an outcome which would eventually be used in a mosaic piece that was to be displayed around the school site. i didn't enjoy using this material as i found it messy and it dried out quickly resulting in a lot of water being used, enabling you to keep shaping to your desired outcome. you also cannot apply a great amount of detail into clay as it becomes fragile and likely to break. for these reasons i chose not to use it in my final piece as i was cautious that it might become too fragile and when assembling to the wall would possibly crumble into pieces. i also found the clay to be a long process's which involved firing and glazing and found this agitating as it would slow the process of my final outcome. one thing that concerend me was that you cannot guaranteen all the air bubbles have been pummled out of the clay piece, resulting in it being ruined when fired as the clay would explode. i was not prepared to take this risk of it exploding and having to create the pieces from scratch again.
