Subject: Please tell me how to get rid of a weird, green, powdery mold ?????? I have a piano that was externally covered with a bizarre-smelling, bright green powdery organism. I wiped as much as I could off with alcohol, but it still smells weird and sort of dangerous. ( How dangerous is it ??? ) How can I get rid of this ? All I have been able to think of is putting a plastic tent over the piano, and pouring a gallon of lacquer thinner - or something- into a pot under the tent, in hopes that the fumes will kill the spores ? I might take some of them to the University, too, to try to identify them. The strange thing about this is that the piano was not in a very humid environment, but the powdery mold grew 1/16 inch deep in places on the case. Thump Hey thump, For once you've stumbled in your own inimitable way on something that is truly dangerous. This is probably Paris Green, a powder used to combat insects that is loaded with arsenic. I worked for a piano store in Texas many years ago and quite a few old pianos from out in the "country" had this stuff on the key beds. Careful my friend The Columbia Encyclopedia, Sixth Edition. 2001. Paris green also called Schweinfurt green, an extremely poisonous, bright green powder that was formerly used extensively as a pigment (e.g., in wallpaper) and that is sometimes used as an insecticide or to kill plant fungi; it must be used with great caution because of its poisonous nature. Chemically it is a copper acetoarsenite that may be prepared from arsenic trioxide and copper acetate. __________________________________ Tom Driscoll RPT ------------------------------ Date: Sun, 4 Apr 2004 22:14:41 -0600 From: "Joe And Penny Goss" <[email protected]> To: "Pianotech" <[email protected]> Subject: Re: Please tell me how to get rid of a weird, green, powdery mold ??????

On eompletion of the :present work I wish to acknowledge the assistance of Dr. Stewart :r. Lloyd, who has offered many valid suggestfons and aided materially in making the work a success. I also.wish to thank the Department of Chemistry of the University of Alabama for making the research possible. Marion Vaun Adams University, Ala. May 1, 1924. THE ELECTROLYTIC OXIDATION OF POTASSIUM ARSElHTE. Potassium arsenate is a comparatively unknown compound, that is, very little experimental work has been done with it, and since no important use has been found for it no attempt has been made to produce it in large quantities. Several arsenic compounds are very useful in destroying insects whic~ have prov,en themselves enemies to the life of eco nomi~ plants. Probably the first of these was the well-known Paris Green which contains copper and acetic acid as well as ar senic. As copper was a fairly expensive metal, and since the acet ic acid served no useful purpose, this was followed and to acer tain extent replaced by lead arsenate, which does the same work at a considerably less coat. The users of Paris Green usually ass ociated the green color, due to copper, with its effectiveness, so that arsenate of lead, which is white, had a strong prejudice to overcome at first. Another member of the arsenic family to come into prominence is calcium arsenate.

Studies of Derris, Nicotine, Paris Green, and Other Poisons in Combination with Molasses in the Control of the Gladiolus Thrips '
STUDIES OF DERRIS, NICOTINE, PARIS GREEN, AND OTHER POISONS IN COMBINATION WITH MOLASSES IN THE CONTROL OF THE GLADIOLUS THRIPS ' By HENRY H. RICHARDSON 2 Assistant entomologist, Division of Truck Crop and Garden Insects, Bureau of Entomology, United States Department of Agriculture INTRODUCTION A spray containing paris green and brown sugar was the most effective of 14 insecticidal mixtures tested in the field against the gladiolus thrips (Taeniothrips gladioli M. and S.) in 1932 (10\^ owing, apparently, to the persistence of a toxic jresidue on the foliage. In order to study more closely the action of this and other spray residues on various thrips, the investigations reported in this paper were started, and were carried out under laboratory and greenhouse con- ditions in 1932-33. Unless otherwise stated, the experiments were made on the gladiolus thrips. METHODS Three kinds of tests were made to estimate the effectiveness of various spray residues. (1) Laboratory tests against young larvae hatching from sprayed foKage over a period of 6 to 8 days after the application: Potted gladiolus plants from 10 to 14 inches high were infested with from 10 to 15 adult female thrips 8 to 10 days before the application of the spray, in order to have many eggs in the foliage at the time of treat- ment. All thrips were removed from the plants before the spray was applied. After the spray deposit had dried, a band of sticky material was placed just above the leaf sheaths to prevent migration of the young larvae that had hatched from sprayed foliage. Figure 1 illustrates this method.

Philip Ball the Invention of Colour
Philip Ball: The Invention of Colour 1 Philip Ball The Invention of Colour The 2011 Van Gogh exhibition at the Royal Academy in London was widely praised for revising our view of the Dutch artist. Its central focus was a selection of Van Gogh’s correspondence with his brother Theo, and these letters show that he did not work in a crazed frenzy, as the romantic legend might have us believe, but was methodical and thoughtful about his technique. The letters, which are of course long familiar to art historians, reveal a man passionate not so much about love and death as about art, and in particular about its techniques and materials. One great source of inspiration for Van Gogh was colours, especially the new colours that during his lifetime had only recently become available to artists. He wrote to Theo that: I have got new ideas and I have new means of expressing what I want, because better brushes will help me, and I am crazy about those two colours, carmine and cobalt. Cobalt is a divine colour, and there is nothing so beautiful for putting atmosphere around things. Carmine is the red of wine, and it is warm and lively like wine. The same with emerald-green. It is bad economy not to use these colours, the same with cadmium.1 This focus on materials is not unusual among artists. Van Gogh’s friend Paul Gauguin was preoccupied on Tahiti not with metaphysical questions – where we are from, where we are going – nor about his sexual relations with the local women, as again legend might encourage us to believe, but about the very prosaic difficulty of getting the pigments he needed.

Chemical Compatibility Storage Group
CHEMICAL SEGREGATION Chemicals are to be segregated into 11 different categories depending on the compatibility of that chemical with other chemicals The Storage Groups are as follows: Group A – Compatible Organic Acids Group B – Compatible Pyrophoric & Water Reactive Materials Group C – Compatible Inorganic Bases Group D – Compatible Organic Acids Group E – Compatible Oxidizers including Peroxides Group F– Compatible Inorganic Acids not including Oxidizers or Combustible Group G – Not Intrinsically Reactive or Flammable or Combustible Group J* – Poison Compressed Gases Group K* – Compatible Explosive or other highly Unstable Material Group L – Non-Reactive Flammable and Combustible, including solvents Group X* – Incompatible with ALL other storage groups The following is a list of chemicals and their compatibility storage codes. This is not a complete list of chemicals, but is provided to give examples of each storage group: Storage Group A 94‐75‐7 2,4‐D (2,4‐Dichlorophenoxyacetic acid) 94‐82‐6 2,4‐DB 609-99-4 3,5-Dinitrosalicylic acid 64‐19‐7 Acetic acid (Flammable liquid @ 102°F avoid alcohols, Amines, ox agents see SDS) 631-61-8 Acetic acid, Ammonium salt (Ammonium acetate) 108-24-7 Acetic anhydride (Flammable liquid @102°F avoid alcohols see SDS) 79‐10‐7 Acrylic acid Peroxide Former 65‐85‐0 Benzoic acid 98‐07‐7 Benzotrichloride 98‐88‐4 Benzoyl chloride 107-92-6 Butyric Acid 115‐28‐6 Chlorendic acid 79‐11‐8 Chloroacetic acid 627‐11‐2 Chloroethyl chloroformate 77‐92‐9 Citric acid 5949-29-1 Citric acid monohydrate 57-00-1 Creatine 20624-25-3
