Cuneiform to left-to-right in horizontal rows (rotating all of the pictographs 90° counter-clockwise in the process) and a new wedge-tipped stylus was introduced which was pushed into the clay, producing wedge-shaped ("cuneiform") signs; these two developments made writing quicker and easier. By adjusting the relative position of the tablet to the stylus, the writer could use a single tool to make a variety of impressions. Cuneiform tablets could be fired in kilns to bake them hard, and so provide a permanent record, or they could be left moist and recycled, if permanence was not needed. Many of the clay tablets found
