on 02024-04-03#Andy-Ward on #bootstrapping clay for #ceramics from dirt, part 2. Recommends looking for “crackle texture” on the surface to locate dirt with a high clay content, then feeling for hard lumps. Later screen the clay to remove large particles, then paint strainer bags for removing silt, and levigation if that’s insufficient. #scouting #video
on 02024-04-03#Andy-Ward on #manufacturing #ceramics from store-bought materials in the city. Some talking-head filler. But mostly he buys clay at Hobby Lobby and makes pottery from it with pottery tools from Michaels (another craft store) and fires it in his yard. It’s probably a ball clay body, Hobby Lobby Moist Pottery Clay X-15. He tempers the clay with a bunch of sand from a nearby dry wash riddled through a screen from his house window. He coils the pot in a thrift-store bowl, protected with a wet handkerchief; the bowl allows him to rotate it. Before firing he stone-burnishes it with petrified wood. To protect his driveway from burn marks, he dumps another bucket of sand on it. He preheats the pot in the kitchen oven to dry it, then uses three bricks on the sand to make a sort of three-stone stove to hold up the greenware pot, then fills up the rest of the fire pit with charcoal briquets. He builds the fire pit three bricks tall, without mortar, puts an upside-down metal bucket (US$19) over the pot to prevent the charcoal above it from damaging it, and covers the top of the charcoal with a barbecue grill supporting large pot shards to keep the heat in. His thermocouple registers 700°, and the pot did sinter properly despite the clay being labeled for cone 5 (about 1100°). In total he spent US$97. He calls the three-brick technique “urban Anasazi”, crediting Tony Soares. #video
