Terminology and Science Museums

Automatic TRANSCRIPT

So we can have a dialogue again. This is exciting. I love talking about museums with my museum friends and I hope you guys like it too but first first of all I wanted to. I neglected to mention something in my last episode with regards to conservators and this is very important for trivia purposes. One of the best solvents for gently cleaning the surface of paintings is human saliva and that sounds gross in weird but in fact any conservative that you talk it was like Oh yeah absolutely spit on that well not spit on it. I actually I got a chance to do that at work. The other you've got to spit on I got to spend on some painting raining so We were cleaning some Oil on board me and my coworker Carol. Hi Carol she doesn't listen to this podcast and She gave me a bunch of thin sticks and a bunch of loose cotton and she taught me to grab a piece of cotton and roll it up and stick it in my cheek and let it sit there and then pull it out. Roll it around the stick and then gently like buff. The surface of the vichy was hazing. You she he did the same thing. We're both both like cotton or cheeks like like the Godfather and cleaning the surface of paintings and it is this is an excellent solvent because it has a gentle and like I'm enzyme that breaks down the surface of dirt but doesn't harm The the image the image or the varnish. That's the word I'm looking for and this is why people don't want you to get up close and personal with the paintings museums because it's covered and spit. They're covered in human spirit. You guys just thinking they don't want you to spend on at least don't spit on them because it will break it down eventually eventually. Also zoos museums yes. One hundred percent hundred percent user museums. They have a collection process. They collect animals and they have a loan process. They loan animals to other museums for certain amount of time. There's paperwork involved. They have the accession process. It's more gruesome than a normal museum process shirts. They D- Accession. There's paperwork involved when an animal shuffles off this mortal coil. So I wanted to give a shout out to you my cousin the zoo not my my work cousin the chiefs that your cousin is zoo. Steve's yes yeah Steve's brothers the Internet my cousin Xue facts okay we we. We have a friend in listener yes Jane Liz Zookeeper Oh keeper. Yes Hello James. Hello James and we decided we're just going to go to the zoo with a microphone and having talked to us. I think it's a good idea and I think I think he would be down for it. He's been like really. I mean I feel terrible because we have been in touch with him and we just have not gotten a chance to like hook up and actually do an episode. But he's a great guy he he has very interesting work. He's funny interesting and we're definitely going to do an episode soon. And that's I think we definitely should go to the zoo do like real. NPR Shit Man Mandalay Bay. She goes to the zoo. I love that okay. That's it misinformation goes to the zoo. Get Ready James. We're coming for you all right museum terminology. Time time okay. All of these terms are for my award. Winning powerpoint presentation entitled Life Is Short and then you die physical deterioration and how to prevent it. It is not award-winning. It's just one of my powerpoint from class but okay I term inherent vice. which was my team? Name for Trivia and Grad School and. Yes we want a lot Inherent Vice is the tendency and physical objects to deteriorate because of the fundamental instability of the components of which they are made as opposed to deterioration caused us by external forces. What does that mean it? Basically means that the makeup of the object is slowly destroying it from the inside. And there's nothing you can do about it. A good example of this as newspapers the process by which the paper is made is very acidic which causes the paper to yellow and crumble eventually which is not reversible by any conservation mean all objects have some kind of inherent vice as a result of the baseline law of entropy of course but we're not going to get really philosophical about this because that's just looking into an abyss is that we just don't have time for today. My students in my injured archives course get a whole week of me just telling them how terrible everything the thing is. Light is bad. Water is bad. Air As bad heat is bad touching things as bad like just. Don't yeah just don't that's the that's basically. Yeah this is your stuff is going to die. Yup Life is short and then you die. That's why I called that. My students laugh but it's true. The next term is foxing. Your must be familiar. smiliar with this. It is an age related process of deterioration that causes spots and Browning on old paper documents. The name may derive from the Fox like Reddish Brown color of the stains or the arrest. Chemical Ferric Oxide which may be involved paper so affected is said to be Fox. I see this a lot with like bookbinding Oh yeah absolutely foxing also occurs biological study skins or specimens as an effective chemical reactions or mold on Melanin. The causes of foxing aren't super stood. It might be mold or the oxidation of metals. Like iron or copper in the pulp or rag from which the paper is made but no one is entirely sure it is reversible but it is kind even intensive process so a lot of times if the paper is already unstable foxing. Isn't that big of a deal and so a lot of conservatives we'll just leave it mhm unless it's like super bad and you can't actually read the paper yeah The next word is crippling Crippling the distinctive network of fine cracks in glass which is visible to the naked eye It's one of the symptoms of Glass Disease Aka sick class or glass s. l. nece nicer bones. Yup Bird bones. Glass disease is caused by an inherent instability the chemical composition of the original glass formula It is irreversible double but able to be slowed down by tight climate control which we will talk about in a moment and and Lauren did a really great episode heart glass. Yes I did an episode episode twenty one year. So we're back there in the catalog early enough first year and also if you like glass may I plug the series blown away on Netflix. which there's like competition show about glassblowing very fascinating so yeah glasses? Amazing like if you're a local New York state. I highly recommend the Corning Museum of glass which talks about the science the history the art and like another thing of glass. It's just all about glass and it's a big beautiful museum that got a great a gift shop off their gift shops fantastic and they do hot glass shows where they actually like make glass in front of you and talking about the process and it's really cool So highly recommend and go to the Corning Museum of Glass. The next term is called cobbling cobbling is a plea distortion of paper parchment or textile. It appears as has wrinkles puckers or ripples often in parallel ridges without creases liked buckling but appears in waves. So cobbling just kind of looks looks like like a rumpled sheet basically like on your bed also just as an FYI words like weeping oozing desiccation or drying out offc gassing the evaporation potentially dangerous chemicals into the air or fry -able which is easily broken apart or flaking tends to be words used in other fields as well but all have to do with pound object is damaged or breaking down the just going back The like this cock owing paper happens because Paper if it absorbs water and then when the water out so this is why you don't want your humidity and your temperature. Allocate Awhile Talk Yeah. That's that's a big thing that'll happen that you can like clearly visible that Yudo. Something's wrong paper starts doing yeah. It's a very obvious symptom Kim of that also a couple of words that are not necessarily damage But definitely our weaknesses in the object. So so this term correct floor. Crack Laura's a fine pattern of dense cracking formed on the surface of materials usually oil paintings. It can be a result of drying aging aging intentional patterning or a combination of all three and the term is most often used to refer to temper Oil paintings but it can also develop old ivory carvings painted miniatures on ivory backing. Recently analysis. Chrysler has been proposed as a way to authenticate art basically. It's just the way that paint is layered in the process of actually painting getting the piece of artwork sometimes certain layers Dry faster than others or there is an off gassing process during the drying process and it damages the surface level and so it actually shrinks or expands spending and causes these fine cracks Which is interesting Crack floor in Pottery is called crazing in that at similar in that it's fine. Cracks appear on the surface of the material most often the glaze layer of pottery ceramics and beautiful it is beautiful and especially like both cracker crazing. One could argue is desirable desirable in certain cases. Like when you see Chrysler and a painting you know it's old it's an antique Lens Air of like authenticity to it. crazing and pottery is seen as like a textural benefits and it does make the peace weaker to a certain extent. You're not supposed to like DOC put. You're not supposed to wash or soak pieces of pottery. That have crazing on them. Because that means that there's a weakness in the water can get into the poorest part of the pottery but it is very beautiful in some potters and artists. Like make sure that it is purposeful like they purposely fire. Fire it so that there is some crazy
