you take a lot of clay flatten some of it to male the walls then make the roof the same way then you can make a ground or not then you can carve a door or a window or both you can do anything on it
If it's real clay, dug from the ground, it's fine to use with mould on it. In fact, mould improves the plasticity of clay (which makes it easier to work). The mould will all burn off in the firing. If it's synthetic clay, some sort of plastic stuff that hardens in the air and does not need firing in a kiln - sorry, no idea about whether mould affects it.

It is so because metals cannot be extracted from minerals in a convenient way. E.g.:- Aluminum metal is found in both minerals: clay and bauxite. Aluminum metal is extracted only from bauxite in a convenient way. So, bauxite is an ore of aluminum. On the other hand, it is not extracted from clay so clay remains only as mineral not ore of aluminum.
