All That Glitters….
By Emma Fooks
At this time of year, Christmas cards and festive greetings make daily appearances in the deliveries to our UK headquarters, gracing them with a sprinkling of glitter and adding a little extra brightness to the day. As I’m sure is the case for many of you, I have fond memories of adding that extra bit of magic to my artwork as a kid, when I was allowed the treat of getting the glitter out.
Now that I’m older, I can appreciate why the parental view of glitter might not be so rosy – it gets everywhere! Even worse, it sticks to things.
One of the joys of being surrounded by technical experts is that my musings over such things as the difficulty of cleaning up the glitter are often met with a detailed explanation of the science involved (along with some good natured teasing, of course).
I’m reliably informed that the ‘stickiness’ of glitter is a result of its susceptibility to becoming electrostatically charged, and that this is also an issue for many powders – with far greater industrial relevance than glitter!
By the new year I’m confident there’ll be no more glitter in the office, but for those of you with more persistent problems relating to electrostatics, I’m pleased to be able to trail new research that we’ll be publishing, examining how electrostatic charge influences powder behaviour.
Watch out for the new paper in 2012 – in the meantime, enjoy the added brightness that glitter brings to some of the shortest daylight times of the year.
Until then, along with all my colleagues here at Freeman Technology, I’d like to wish you all:
