David, our course leader started us off with a basic introduction into clay wedging. I did not realise that different wedging techniques affected the arrangements of the platelets within the clay body in different ways. Thus, stack-and slam wire wedging is more suitable for slab building and not suitable for throwing on the wheel. Here the clay platelets should be arranged in a spiral or circular way not in horizontal layers. That is a bit of a pity as stack-and-slamming is the most easy way for me to wedge. The rams-head technique is a real strain on my wrists and I have not mastered spiral wedging.
We went on to making some slab tiles, which we decorated with different textures. Here are my more detailed notes for this session including how I made these textures:
