5 noun modifiers after adjectives
Note that noun modifiers (which often classify, or refer to material) usually follow adjectives.

6 commas
Before nouns, we generally use commas between adjectives (especially in longer sequences) which give similar kinds of information, for example in physical descriptions.
a lovely, long, cool, refreshing drink
an expensive, ill-planned. wasteful project
But commas can be dropped before short common adjectives.
a tall(,) dark(,) handsome cowboy
For and with adjectives. see 16. For commas with alld, see 476.1.

And is necessary when two or more adjectives (or other modifiers) refer to different parts of something, or different types of thing.
