Coloured glass is something that’s commonplace in our lives, from the green of wine and beer bottles, to the red, yellow, and green of traffic lights. The origin of these colours is something we don’t give a lot of thought to, but a range of different elements are responsible. This graphic takes a simple look at […]
If you’re currently a student, then you’ll no doubt often make ample use of highlighters during revision. Even if your studying days are far behind, you probably still use them from time to time. But what are the chemicals behind their luminous colours? This graphic looks at some of the possible dyes that can be […]
Following on from the start of the Chemistry Advent Calendar yesterday, here’s another festive post, this time looking at the chemistry of the poinsettia plant. The red leaves of the poinsettia plant can be used to make a pH indicator, due to their chemical composition; this is actually something of an upgrade on one of the […]
It’s Fireworks Night here in the UK tomorrow, which means fireworks (obviously), bonfires and sparklers. We’ve looked at fireworks in a previous post, so this time around it’s time to take a look at the chemicals that go into producing sparklers, and their various roles.
Halloween’s almost here, which, for a large number of costumes, will require a liberal dousing of fake blood to complete the look. You probably already have a pretty good idea of the reasons behind the red colouration of human blood that fake blood mimics. However, red is not the only blood colour available – it also […]

You may have wondered what happens when you snap a glow stick to activate it; by doing this, you’re actually kicking off a chemical process that eventually leads to the production of the coloured light. But how does […]
