In this job interview conducted at Pittcon 2023 in Philadelphia, Pennsylvania, we spoke with Dr. Gregory Smith, Conservation Scientist at the Indianapolis Museum of Artwork, about the scientific analysis and conservation of art.
Could you make sure you introduce you and your present-day research actions?
My name is Greg Smith. I am the Otto N. Frenzel III Senior Conservation Scientist at the Indianapolis Museum of Art at Newfields. I function in cultural heritage and chemistry, authenticating, finding out, and encouraging protect artwork.
What 1st attracted you to this discipline?
As an undergraduate, I went to a little liberal arts faculty in Kentucky, Centre Higher education, to be a chemist. I took a basic education and learning requirement class in cultural anthropology. At the time, I most likely experienced no idea what those words and phrases intended, but two weeks in, I was hooked. I knew that whichever I did in chemistry, there would have to be a cultural element.
Could you define what conservation science is and its role in cultural heritage?
Cultural heritage chemists, or conservation scientists, use chemistry and physics instruments to review artwork resources. This information and facts is employed to interpret the artwork, recognize it much better, or maintain it extensive-term.

What analytical techniques are generally utilised to uncover the secrets and techniques of art and artwork heritage?
My laboratory at the museum would be familiar to anyone who has been in a university laboratory. We use different analytical tactics, this sort of as molecular and elemental spectroscopy, chromatography in the gas and liquid phases, and microscopy making use of light-weight and electrons. We also use several more esoteric procedures like thermal analyses and accelerated growing old instruments.
Why is it so essential to have an understanding of the chemical degradation of an artist’s components, and how can it assist to boost our comprehending of cultural heritage?
If your intention is the extensive-time period preservation of the artwork or cultural heritage, and you do not have an understanding of its weaknesses and what will direct to its degradation, you will not be equipped to halt it.
For instance, if we are fearful about fading dyes, we would check out to comprehend that system to decide if it is photooxidation. If so, we may perhaps use anoxia to protect a watercolor print in its frame.
Though they look to be superficially independent, what is the scientific overlap concerning artwork examination and criminal offense scene investigations?
They feel like disparate fields. You have researchers who are fixing crime and researchers who are attempting to maintain artwork, but they do have a whole lot of overlap.
It commences with the experts themselves. We share an investigative frame of mind and a very identical tool established. The samples are also very similar – typically small, treasured, and irreplaceable. Also, anything at all can conclusion up at a crime scene equally, anything can conclusion up in an artwork museum.
What strengths does a forensic solution give to cultural heritage at present?
There is a forensic principle that when a criminal is committing a crime, they leave traces that can be read through if you can detect them. This same attitude applies in our discipline.
If we feel about the record of an artwork, how it has changed, or how it was made, every leaves some trace. If we can figure out how to assess or detect these, we will have an understanding of something about this artwork’s history, condition, and craftmanship.
On the topic of artwork connoisseurship, how have you seen this evolve?
A lot of connoisseurs depend on their eyes or their arms to ‘read’ an artwork to fully grasp it. But with the introduction of cultural heritage chemistry as a discipline, there are now so lots of much more instruments that can be made use of to visualize artwork, maybe outside of the obvious variety working with infrared or X-rays.
Supplies characterization strategies can also present info you simply are not able to get from your eyes or hands. It is innovative in that perception.
Could you discuss a little little bit about the distinct roles that science can participate in in arts?
Look at the interface concerning artwork and science. For instance, researchers who make new artwork products these are the formulators that might function for paint or pigment organizations. There are individuals like us that evaluate or authenticate artwork that could conclusion up in museum collections, as perfectly as conservators who restore and treat the artwork and are also properly trained as researchers.
The most elementary degree is that there is a science that occurs in the genuine development of the artwork. If you feel of the patination of a bronze sculpture, that is all corrosion chemistry going on.
What are the primary challenges in the industry of cultural heritage?
Numerous problems are shared in the much more mainstream sciences, together with funding, notably for a really applied subject like mine, and big details sets.
Lots of of our techniques, which employed to require discreet, level-and-shoot spectroscopic sampling, are now 2D imaging tactics. You may perhaps stroll absent and, in the early morning, occur back to hundreds of hundreds of spectra. How do we deal with those people intensive information sets to tease out the facts we are fascinated in?
As our world results in being smaller and we vacation, not all artwork can come to the lab. We have to consider the lab to the artwork. Miniaturization and portability of devices enable me to work in our art character park guiding the museum, or it may well make it possible for me to vacation to Egypt and be element of an excavation functioning in a tomb.

What has been the most poignant piece of artwork or artifact that you have worked on during your job and why?
I have been pretty lucky to do the job on some breathtaking artwork, this kind of as Van Gogh, Rembrandt, and Gauguin. It would be uncomplicated to say a person of these due to the fact it certainly raises the hair on the back again of your neck when you are peering down a microscope at a Van Gogh, but at the similar time, we may well be functioning with a freshly excavated ceramic pot. Below, you are keeping a little something that a human hand has not touched for 2,000 decades, which can also be a very specific party.
What are you doing work on appropriate now that you are primarily thrilled about?
We have labored on emissive pigments, such as Dayglo and vibrant neon pigments for the last number of yrs. We have been learning their compositions and pondering about them in terms of exhibition.
We have just opened a present at our museum of Stephen Sprouse, who was a designer from Indiana, element of the punk rock era. In the eighties and nineties, he utilised a large amount of neon and glow-in-the-darkish colours. We will need to realize these pieces prior to we put them on exhibition to know what changes to assume as a final result of that.
What are you most looking ahead to about Pittcon in San Diego?
The exhibit is generally about becoming on the floor and searching at the most current innovations. We have to change infrared and Raman spectrometers, so I want to search at new developments in those people instruments that debuted at the exhibit.
Pittcon was put on pause for an in-human being event for two several years. But why is it so significant for people to occur to these in-particular person activities? What advantages can they attain?
If you think about the exposition ground, you do not get the opportunity to kick the tires on that lots of devices in 1 go unless you are at an in-person party like this, and it is a probability to satisfy up with colleagues. In the symposium I spoke at, I experienced friends I had not witnessed for five or six several years due to the fact they dwell in Australia. An in-person assembly is an outstanding chance to do that.
