This was made for our "Going Opposite" Facebook group page (notice one fish is swimming the other way). Only three tile shapes are needed. The fish cutters were 3D printed to both cut and stamp at the same time. Multiple sizes of the triangle and trapezoid were made to accommodate irregularities and keep joints tighter. The clay is M340 and the glazes are Amaco Celadons and Potter's Choice (for brushing). I found the best way to paint them was to glue them down to a plaster slab with a few drops of glaze (it was easy to scrape off when the three coats had dried).
This is the most complex shape known that can fit together organically. It was just discovered by mathematicians in 2023. It is easy to cookie-cut these out of clay (notice the cutter I made at the top). Placing the tiles is tricky because it is only logical to seek a pattern, but that does not work. Starting with a center tile and moving outward in a spiral around it seems to be the best way. Mathematicians are seeking to prove that placement can grow infinitely without ever repeating a pattern. Making the cookie cutter in Fusion 360 was easier than expected because the shape is built from the pie-slices that result from cutting a regular hexagon into six pieces midway across the straight sides. Because of the complexity of the shape I have found that it is best to print multiple cutters (I can do eight at a time), and stamp the shapes without using stretch wrap (letting them dry overnight in the cutters). The randomness seems confirmed in that when I piece together a few dozen tiles it is very difficult to do a count (because they are not in rows). In addition, to piece together 28 tiles requires turning eleven of them over - if there was a pattern I would expect to turn over exactly half of them. One issue: To create a setting with straight sides it appears I will need a dozen shapes.
Cookie Cutting clay with 3D printed cutters
We are finding more and more applications for this simple process of cookie-cutting shapes in ceramics. You won't believe whats possible and how easy it is to get started.
