Commas, Aluminium Pots

Using Commas to Change Meaning

In some cases, I was aware of commas changing meanings. "Panda eats, shoots and leaves" has a very different meaning from "Panda eats shoots and leaves." However, there are cases where I was not conscious of there being a difference. In the sentence "I fed the dogs which looked hungry" I picked out the hungry dogs and fed them whereas in the sentence "I fed the dogs, which looked hungry" I feed all the dogs and they happened to look hungry.

Using Aluminium Pots

When dyeing, using an aluminium pot can cause unexpected results as there is always some aluminium dissolved in the liquid in an equilibrium with the solid pot. Aluminium salts are mordants.
