What Am I? The Random Summer One

Below I’ve listed the key chemicals or elements found in a commonly available  product, which may (or may not) be slightly UK-centric.  All chemicals drawn below are part of the same product.  I’ve drawn the chemical structures of principal components where simple and appropriate; given the E number or CAS number (however tempting Sigma-Aldrich catalogue numbers would be) if no simple chemical structure exists for an additive; and given the chemical formulae or name if neither of the above make sense.  See if you can guess…

What Am I? The Model Edition 1

I have recently acquired some rather beautiful chemical models. They are a bit dusty and I’m still a little lost as to where in my office they will go, but for now, why don’t you try and figure out what they are? The photos were all taken against my gorgeous office carpet and I have taken care to make sure the labels are the wrong way around.  I’ve given 2 views of each model. If no one gets it within 24 hours,…

A Chemical Treasure Hunt

If you’ve been reading here for a while, you’ll know that one of my projects is to work with the Blists Hill museum to identify the contents of jars in its Victorian Pharmacy.  This is a fairly slow process, mainly due to the constraints of other pressing tasks such as teaching, but it is a fascinating process.  The pharmacy exhibit has a number (in excess of 300) of  jars of pharmaceutical ingredients of some description, mostly labelled but some are…

                      Remember these? Or if you’re unfamiliar with the ‘flying saucers’ (hence a clue on Twitter: Fox Mulder’s favourite sweeties), they are essentially sherbet wrapped up in coloured rice paper (starch really). Sweeties is really a misnomer – in many cases the joy of sweets is the sourness, often caused by tartaric, citric or malic acid, and a fizz caused by a reaction between the acid, water (such as saliva…

Mmmm Spicy!

A few years ago while living in Vancouver we returned to our basement apartment from a day’s shopping.  After about 5 minutes we felt our throats were very scratchy and our eyes were burning and we couldn’t really work out why.  There was no obvious odour in the apartment although it was perhaps colder than usual.  We opened the outside door and all the windows and ventilated the place for an hour or so.  A few hours later, our neighbour came back….
