A brick or wedge-shaped stone forming an arch is called a "voussoir." These stones are positioned and interlocked to create the curve of the arch and distribute the weight evenly downwards and outwards to the supporting columns or walls.
There are no pool table markings except the foot spot dot. It is called the rack spot by some people.
As the clay falls it has kinetic energy
In Table Tennis, as long as the ball touches the table, it is counted, the markings aren't important.
1) Wear an apron when handling clay 2) If you are using a knife, make sure it is not left on the table unattended 3) When cutting, cut onto a cloth or protection, NOT the table 4) Put a cloth/protection down when using clay otherwise it will stain the table 5) When finished, always clean up spare clay, especially dry clay as that can be inhaled.
They used a stylus to write on clay. If they wanted to keep what they'd written they baked the clay to make the markings permanent. This type of writing is called cuneiform

Cuneiform was typically made by pressing a stylus into clay, creating wedge-shaped markings. Clay tablets were then dried or fired to preserve the writing. The clay was the primary material used for cuneiform writing in ancient Mesopotamia.
I have a tilt top table that was my grandmothers. The table has a paper label on the bottom that reads. Charles of Longon, for London and New York. How do I find anything out about this label and table. Thanks, Tigerli461
If there is no mark on the rails, the table is not marked. It is possible that there are markings or tags that can be found when you take the table apart, but this is not likely. Many pool tables are not marked by the manufacturer.
You don't. There are no markings that should be on the rails or cushions of a pool table. If you make a mark during a game, it can be a foul.
You can make bricks by putting clay in a furnace and smelting it.
