QotD: If mud is dirt plus water, what is clay?

Clay is at the fine particle end of the dirt continuum. Sand is not. Once clay is saturated, it will block more water from passing through. Wet clay will support you better than wet sand, which may become quick. If you tramp through clay, helping a friend near Stratford-on-Avon plant a tree in a depression caused by a bomb falling during the war, it will cling to your boots, more and more until you are stopped in your tracks. You will need a knife to cut it off. You can wash sand off with a hose. Clay, deconstructed, has more potential words than mud. If you form clay into a pot shape, and cook it in a kiln, it will lose its water-blocking properties. To restore them, you must use a glaze. Ham is very good with a glaze. Clay incorporates the word lay, which is sexier than spelling mud backwards. The best dirt plus water can do is something like tri pus raw, which is disgusting and slightly misspelled. Clay castles last longer than sand castles. Mud pies are seldom eaten. You’re much better off with the ham, although fish is better for your brain. Brain may be jumbled to form in bar, which is where I’m writing this. Hurray for clay rhymes beautifully and is meaningful. Mud is dud also rhymes, but is stupid. The End
