Mould, moulding and mouldy - fungal friends, novelty and replicability

I'm thinking about mould.

Mould is a furry growth of minute fungi occurring typically in moist warm conditions, especially on food or other organic matter. "Mould may flourish unhindered".

Mould has given us taste, has given us nourishment - cheese is mould - mould has saved lives, giving us crucial bacteria-vanquishing molecules to treat our bodies when they become colonised and overrun by bacteria, and it has also taken lives, populating lungs with toxic spores with psychological and physiological side effects. Mould is both friend and foe.

Mould is form - if someone is from or in a particular mould, they have the characteristics of a certain person: "she's cast in a very different mould".

Mould clings and fits and shapes very closely to your body. "Her tight fit costume moulded to the contours of her body", but it can also suffocate and begin to take over "she kept trying to mould me into something I didn’t want to be".

"Breaking the mould" means that the particular artefact cannot be replicated or others made to look like it. It comes from when artefacts were casted in moulds. A mould/mold is a container that you pour a liquid or soft substance into, which then becomes solid in the same shape as the container. You do something and it breaks the container that allows scalable copy-paste replication of a certain way of doing things, you literally break the sameness.

You can use mould-breaking to describe someone or something that completely changes the way something has traditionally been done.

Slowly, a new mould is created from the invention and novelty. That becomes the new mould, replicating the way of doing things, until a new invention comes along to "break the mould"

To be mouldy could mean to be housing furry fungal growth, but it could also mean to be the same, to shape others, to be like a "mould" - a container used to create many other things the same as itself.
