i am interested in investigating substances which could be used to dye paper which one could from that moment on, tell easily from colour the length of time elapsed since dying. time period of interest one month; and i assume oxidation would be an easy and accessible (and safe!) way to acheive this effect. This is an important part of a wider project but as you can tell chemistry is not my usual area of knowledge. much thanks.
Re: what has the properties of colour change with oxidation?
