The molecules stick together because they're plate shaped. It's like putting two phone books together by putting page over page. if you pull, it will stick together. if you let go, it'll drop and fall apart. thats what clay molecules do.
yes,nonmetals are brittle and cannot be rolled into wires or pounded into sheets +++ Not at all. Synthetic plastics are non-metals, and while some are indeed brittle others are, well, plastic by the true definition of that term! Clay is a natural plastic, and not considered a metal although the clay-forming minerals include complex compounds of metals. Wood is not metallic - but that's not brittle unless dried completely.
It is the Earth's crust.
The change of state that occurs when fat from a roasting dish becomes hard is called solidification. This happens when the fat cools down and transitions from a liquid state to a solid state, typically due to a drop in temperature.
Hard stony clay is commonly referred to as clayey soil. It is characterized by its high clay content, making it dense and difficult to cultivate.
Hard, but easily breakable - dry and brittle.
No, baked clay can't be recycled because it becomes very hard when baked, and it is very brittle to recycle it after.
Reasonably, it depends on whether it is squidgy. =P
When it is heated, it becomes very brittle....And it is very hard to work.
The literal definition is clay and chemicals fired together to create a hard brittle heat resistant material
hard and brittle so YES
hard and brittle so YES
Yes, but if you want to glaze the clay you have to fire it at a low before you glaze it so it is hard - ish.

They get hard and brittle when they dry out.

Hardness is the question of how difficult it is to make an impression on a substance. Brittleness is the question of how easy it is to break. Granite is a stone which is very hard but not brittle--it is hard to carve and also hard to break. A plank of wood is not as hard as stone but is not very brittle. You can carve on it with a knife but it won't shatter if you drop it. Glass is hard and brittle. Chalk is not hard but it is brittle.
