Metal Windows <br />METHOD OF INVESTIGATION <br />Investigation was conducted by removing samples from different painted surfaces for on and off <br />site microscopic inspections. The instrument used was a binocular microscope with I0x to 100x <br />magnifications. <br />The location and number of samples collected was determined by the various architectural <br />details that may contain color changes within a decorative multi -color scheme. Extensive <br />samples were collected to obtain the cleanest and brightest samples possible to assure <br />representative sampling and color identification. <br />ESTABLISHING A PAINT CHRONOLOGY <br />The chronology consists of a sequence of paint layers listed by ge neral color names, including <br />any physical characteristics that distinguish that layer from another. The chronology is not of a <br />single sample but represents the paint sequence of one surface, as compiled from two or more <br />samples from that surface. The chronology may include the point at which any additions or <br />alterations were made to the object being investigated. <br />The chronology is arranged horizontally for the purpose of correlating different details of the <br />object being investigated. The left-hand numerical column represents the layer count for each <br />object. A numerical listing represents a single paint layer or a compound paint treatment. I f a <br />paint treatment consists of more than one application process (layers), each is listed by the same <br />number plus a letter; i.e. 1 a. for a prime coat, 1 b. for a base coat and 1 c. for a finish coat. <br />In the paint chronology, color names (grayish -brown, yellow-brown, light brown etc.) are <br />general terms used only to distinguish differences between adjacent paint layers within the layer <br />sequence while being viewed under magnification. These are not accurate color identifications. <br />Humedd Studios, Inc. • 428 Division Street, Crete, Illinois 60417 • Phone& Fax (708)-672.4218 <br />Page 1 <br />
