A factory worker dip-glazes translucent porcelain plates with her bare hands. Very fast! She works at incredible speed, glazing one every two seconds. Without using dipping tongs. She applies a very thin layer of transparent glaze. While it appears very watery (low viscosity), it is likely high-solids and deflocculated to achieve extreme thixotropic behavior (fluid when moving, gelled when still). The speed of the dip, and fluid sweep while below the surface, ensure that all parts of the plate spend the same fraction of a second submerged, ensuring a uniform layer. Notice also that the plates on the split foam belt dry enough to stack within 10-15 seconds. What about the spot on the rim where she is holding it? Upon pulling the plate out, the glaze is still fluid enough to pool over it as a product of the way she releases it. Notice also that she picks them up with a glove, which means they may be hot (to speed drying). Finally, additions of surfactants and defoamers break the surface tension, enabling air bubbles to pop and smooth over quickly before the glaze dries. One final detail deserves repeating: This is translucent porcelain, maybe even bone china. That means the ware has been bisqued to zero porosity. Wow! |

Factory worker using a stationary-template jigger machine makes each bowl in seconds. He turns a large pile of super soft clay into jiggered bowls, one after another. Notice how he deliberately puts in too much clay but catches the excess efficiently for the next piece. Also notice the inner, likely 3d printed liner, on the plaster wheel head, enabling them to precisely fit it to the molds. |

Factory worker dip-glazes large bisque casseroles in thixotropic glaze Notice the special dipping tong. And the glaze has been tuned to have the rheology needed to not over-thicken. This enables the worker to grab the already-dried first extracted portion of the rim to stabilize the piece as it is pulled completely out of the slurry. |
