That question doesn't mean anything, mass is mass. If you are asking which has a greater mass per unit volume, also known as density, then the air will have a lower density than clay.
Air definitely has lower mass than bricks.
The atom that has the lowest mass is hydrogen. So assuming the same numbers of atoms in each element, hydrogen would be the element with the lowest mass.
Clay wedging is the act of preparing clay for the pottery wheel in order throw your pottery. wedging is accomplished by kneading the clay, usually on a plaster surface, until the clay is uniform in moisture and texture. Some potters like to cut the mass of clay and slap it down hard on the surface and then slap the 2 pieces of clay together with force. The idea is to get rid of any air bubbles and to make the mass of clay evenly moist. This will help the potter to form the clay on the wheel with interference of trapped air bubbles or hard lumps of clay which will cause the piece to be uneven. Also, air bubbles can explode when the piece is fired, especially if the piece is not bone dry.
i don't know clay soil lack air and water
you buy air dry clay and it drys in 10 secs by air
The ingredients in Crayola Air Dry Clay typically include natural clay, water, and preservatives.
The lowest layers, where the air is denser. Air pressure - and density - decrease by 1/2 every 5 kilometers or so, meaning that half of the mass of air is in the first 5 km above sea level (this reasoning makes the simplifying assumption that the Earth has no differences in elevation).
No, it is not safe to put air dry clay in the microwave as it can cause the clay to overheat and potentially catch fire. It is recommended to let air dry clay dry naturally at room temperature.
hobby craft has a range of clay, air hardening and normal. I'm guessing all arts and crafts shops should have clay.
The metal in group 14 with the lowest atomic mass is tin (Sn), which has an atomic mass of approximately 118.71 atomic mass units.
You don't bake air dry clay...so, no problem!
Air dry clay can crack easily if it is not handled or dried properly.
