Indigo originated in India where it was turned into an industry in 300 BC‚ and then it was later discovered and later spread around the world by the Venetian explorer Marco Polo. Throughout the distribution of this plant it replaced the current blue dye of Europeans called woad. It soon became one of the most valued plants in all of Asia. Furthermore‚ Lee states the importance of Indigo by referring to it as a "saint" in line 3. In "My Indigo"‚ Lee talks about how the Indigo has lost its sense of

look‚ many types of washing effects are given to denim fabric. Denim jeans have consistently been fashionable in American culture and also have changed in style significantly throughout the years. Denim was traditionally coloured blue with “Indigo dye” to make blue “Jeans”‚ though jeans denoted a different‚ lighter cotton textile. Blue jeans started becoming popular among young people in the 1950s. In the year 1957‚ around 150 million pairs were sold worldwide. This growing trend continued until

Analysis of Food Dyes in Beverages Samantha Sequito and Anna Steenland Lab Performed: December 3‚ 2013 Lab Due: December 13‚ 2013 Introduction: Different amounts of FD&C Blue I were diluted with water to make eight differently concentrated 10 mL solutions. Samples were placed in the spectrophotometer to determine the percent transmittance of FD&C Blue 1. All of the data was summarized in graphs to predict the concentration of FD&C Blue I in a sample of Gatorade.

Tie dye is haute Sixties is back and we don’t mean bell-bottom pants‚ vests or long hair. We mean tie dye‚ the most sought after patterns this summer. One can hardly imagine the chaotic swirls to be considered high fashion. The mere mention brings memories from the past‚ the wild psychedelic prints and the hippy culture. Yet the colorful patterns are making a comeback with who is who of the fashion industry spotted in one. The demographic might have changed the overall style has changed what hasn’t

TITLE Crime and Dye Lab Special Projects 1 Martin Enem LAB SECTION: BB2 INTRODUCTION Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated‚ the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1 One

Purpose: The purpose of this lab is to find the amount of blue dye #1 in the blueberry pomegranate gatorade. Procedure: We created dilutions using stock solution(10mL stock/0 mL water‚ 8mL/2mL‚ 6mL/4mL‚4mL/6mL‚ 3mL/7mL‚ 2mL/8mL‚1mL/9mL‚ 0mL/0mL). Before we put each dilution in the SPEC 20‚ we put water in a cuvette and put it in the SPEC 20 so we could zero out the percent transmittance. We collected the percent transmittance of each dilution using the SPEC20 with a wavelength of 630nm.

Analysis 1. Examine the structures of the FD&C Red No. 40‚ Blue No. 1 and Yellow No. 5 dyes. What are the similarities and differences in the structures of the three dyes? a. Red No. 40‚ Blue No. 1‚ Yellow No. 5 contain carbon rings and NaSO3. Additionally‚ Red No. 40 and Yellow No. 5 are very similar‚ as they both contain one nitrogen double bond‚ a hydroxyl group‚ and no ions. Blue No.1 contains nitrogen and chlorine ions and N(C2H5)CH2. 2. In the Introductory Activity‚ the developing solvents

spectroscopy create graph to determine the concentration of dye in a sport drink‚ by creating series of standard dilutions of an FD&C Blue 1 Stock solution and measuring the percent transmittance of each dilutions. Results in each dilutions will be use‚ to determine the linear function among various functions (T‚ T%‚ log T‚ - logT) For a Beer’s law calibration curve. The produce provides a model for guided-inquiry analysis of the concentration of food dye(s) in sports drinks and other consumer beverages.
