What does your geological collection represent?
It’s a big question, and it could be a number of different things: the geology of the country, area or town you live in, a set of beautiful colourful and fascinating objects that please you when you look at them or a wealth of scientific knowledge just sitting there ready to be unlocked.
My collection represents my childhood, my fascination with beautiful natural objects and the realisation of the wonderous, boundless knowledge that can be gained from each and every specimen. My collection represents the journey I took to become who I am today (although I still have far to go!).
To me, the meaning of my collection is something very personal, but other collections – like at the Natural History Museum in London and its great mineral gallery – may mean something entirely different. I see the past few hundred years of scientific discovery embedded in those rows of cabinets, and the histories of the people who donated specimens to the museum in the vast corridors of storage behind the scenes.
Collections mean different things to different people too. People will value collections differently and for many reasons, but not just in monetary terms.
Take Sir Arthur Russell, the 6th Baronet of Swallowfield Park near Reading who lived from 1878 to 1964. He was fascinated by minerals from a young age, and at 8 years old he had already visited his first working mine. From then on, he was hooked. His passion lay in piecing together a collection that represented the whole mineralogy of Great Britain and Ireland, and managed to create one of the most comprehensive collections of British minerals to date. His collection became extremely important and well known, and after his death even universities all the way across the Atlantic in the USA wanted part of his collection!
The collection meant everything to him: “It is my earnest hope and desire that this collection upon which I have bestowed so much loving care and so much of my life shall remain intact and be well cared for wherever it finds a resting place”, a quote from Sir Arthur Russell. Arthur’s collection now resides at the Natural History Museum in London in the hope that it would be kept in perpetuity, meaning that it will remain here forever.
The task of keeping objects in the way they were donated is harder than it sounds because all objects and materials will change over time, no matter how careful you are. This type of change is called degradation, and is caused simply by factors such as wear and tear through use, the storage environment (such as high or low temperatures or humidity – the amount of water in the air relative to the temperature) or the amount of light something is exposed to. These factors can cause changes such as breakage, crumbling or fading which alter the condition of the object relative to its original state in which it was given to the museum.
To help slow the process of degradation (a practice called conservation) museums come up with ideas to assess how the material’s condition has changed compared to the state it was originally documented in, and use this to decide how to conserve the material.
Think about your collections. Do you think they will last 100 years and end up in a museum? If so, what might you do to help make sure people can appreciate them like you do, and see the full value of your collections?
