Did you ever find the maker of this mark? I have four cups with the same mark (although I have been debating on whether it is a K or an R) and haven't been able to find anything.
The size usually, or maybe the code for the shape.
Probably just a code used in the factory for that shape/pattern
If it is on the bottom of the pot it will be the number given to that shape of pot, or the style of decoration, for use in the factory or workshop.
Some people make pottery for a living. They make bowls, plates and dishes and sell them. Other people like to make pottery because it is a fun and messy activity. It may appear to be easy, but it can be very hard to get a good shape out of the clay. It is a challenge, which is part of what makes it so enjoyable. It also makes great gifts and allows your creativity to run wild!
Pinch pots are simply clay which is pinched into shape, rather than being made on a wheel or constructed from coils. So all you need is clay, access to a pottery kiln for firming it, and glaze. Clay is all you need for a pinch pot. All you do is rool the clay flat but a little thick and shape a bowl type pot and pinch it thats it I've made one.
Ovoid
An ovoid is a three-dimensional egg-shaped object with a curved surface. It is similar to an oval shape but in a three-dimensional form. Ovoids are commonly found in nature and art as a shape that represents balance and harmony.
Oval/ovoid
No an egg is not a sphere. It is an ovoid. This shape is named after the shape of an egg.
An egg-shaped, three-dimensional shape is an ovoid.
Ellipsoid, Ovoid, Prolate Spheroid, Spheroid
Ovoid wind instruments are a type of wind instrument that has an oval or egg-like shape. The design of the instrument may affect its sound production and resonance due to the unique shape of the chamber. Examples of ovoid wind instruments include the ocarina and the South American pre-Columbian Tumi Pūru.
I was thinking about that myself, recently. The answer is "egg shaped". Mathematically, it's an "ovoid". Eggs vary in shape and there is no exact "formula" for the shape of an egg.
An oval is two-dimensional. An ovoid is a three-dimensional shape based on an oval - like an egg,
A two dimensional figure would be an oval or ellipse. A three dimensional shape could be called an ovoid.
No, sphere bacteria are spherical in shape, while ovoid bacteria are egg-shaped or oval. They have different physical characteristics even though they are both classified as bacterial shapes.
It's an ovoid, not an ellipsoid as some may think.
