I've always thought that mold is the fungus, and to mould is to shape. When talking about it with my colleagues yesterday, I was surprised that this isn't common. Most people use one of the two spellings to refer to both.
Doing a quick search on duckduckgo also confirms that:
- mould is the British spelling referring both meanings.
- mold is the american spelling referring to both meanings.
In my quest to prove them wrong, I was surprised at how wrong I was... until I discovered a few people on the internet who said the same thing:

I'm not looking for what's correct or incorrect anymore, I just find it very fascinating that there are some people who use the words similarly to me, but the vast majority of others who use it in a different way.
So: what's the difference between mould and mold according to you?
You know that there are two unrelated words, and you’ve seen two different spellings—it’s a natural assumption that the latter stems from the former.
Why so many people would pair them up the same (etymologically unsupported) way, I don’t know... maybe we’re used to correlating words relating to art with French, and assuming that words with “ou” come from French as well (and this case just happens to be an exception).
