Colored pencils

Cellulose. Cellulose or starch xanthate cross-linked by titanates can adsorb uranium from seawater (536). CarboxymethylceUulose cross-linked with TYZOR ISTT is the bonding agent for clay, talc, wax, and pigments to make colored pencil leads of unusual strength (537).

Areas of application include wood coloration [45], paper mass coloration [46] and paper surface coating in the lime press [47], the office articles and artists colors sector pigments are used in colored pencils, crayons, and writing and pastel chalks or in water colors, as well as in cosmetics, especially soap [48],... 

This pigment has little impact on the market today and is only occasionally found in printing inks or in office articles, for instance in colored pencils. Its shade is more reddish and its tinctorial strength superior to that of P.Y.l. The low specific surface area of the types which are still commercially available makes for good hiding in print. Solvent resistance and other fastness properties equal those of P.Y.l P.Y.2 is only slightly less lightfast than P.Y.l. 

Applications outside the above-mentioned areas include colored pencils. 

The paint industry employs P.R.22 in air drying systems, in emulsion paints, and occasionally in industrial finishes although there is some danger of blooming, and the appropriate limit has to be observed. Again, P.R.22 is much less lightfast in these media than P.R.l 12. Areas of application include paper mass and surface coloration, colored pencils, artists colors, and other purposes. 

P.R.212 was used throughout the graphics industry and for textile printing, as well as in specialized media, such as colored pencils. 

P.R.57 1 is a useful colorant for a variety of special purpose media, including colored pencils and crayons. A number of countries have legally defined purity regulations concerning the use in decorative cosmetics articles, such as face powder and lipstick. The same is true for cheese casings [11], Suitable grades are commercially available, they are registered in the USA as D C Red 7, in Japan as Red No. 202. 

Incorporated in plasticized PVC, P.B.15, like other phthalocyanine pigments, is usually entirely fast to migration. Moreover, it provides excellent lightfastness. P.B.15 also finds use in various types of PUR foam materials as well as in rubber. Its redder and frequently cleaner shade compared to corresponding stabilized types makes it an equally useful pigment for other media. This applies especially for water-based systems. Textile printing, paper mass coloration, paper surface treatment, and paper pulp are areas of application as suitable for the use of P.B.15 as office articles, including colored pencils, blackboard chalks for schools, and water colors. 

P.B.15 3, like stabilized a-Copper Phthalocyanine Blue, markedly affects the hardening of unsaturated polyester cast resins. The list of applications also includes PUR foam materials, office articles, such as colored pencils, wax crayons, and water colors, as well as spin dyeing of polypropylene, polyacrylonitrile, secondary acetate, polyamide, polyester, and viscose. Used in polyester spin dyeing, P.B.15 3 satisfies the thermal requirements of the condensation process (Sec. 1.8.3.8). 1/3 and 1/25 SD samples equal step 7-8 on the Blue Scale for lightfastness. Textile fastnesses, such as stability to wet and dry crocking are perfect. 

P.B.9 matches the standard cyan for three and four color printing (Sec. 1.8.1.1). The pigment is continually losing significance as it is being displaced by the similarly shaded [3-modification of Copper Phthalocyanine Blue. The latter offers a number of applicational and economical advantages. P.B.9 continues to be used in mass colored paper, textile printing, and in colored pencils. 

Use a Flinn C-Spectra to view an incandescent lightbulb. What do you observe Draw the spectrum using colored pencils. 

Use the Flinn C-Spectra to view the emission spectra from tubes of gaseous hydrogen, neon, and mercury. Use colored pencils to make drawings in the data table of the spectra observed. 

With the room lights darkened, view the light using the Flinn C-Spectra . The top spectrum viewed will be a continuous spectrum of the white lightbulb. The bottom spectrum will be the absorption spectrum of the red solution. The black areas of the absorption spectrum represent the colors absorbed by the red food coloring in the solution. Use colored pencils to make a drawing in the data table of the absorption spectra you observed.

Find, label by name and outline the following families on your periodic table alkali metals, alkaline earth metals, transition metals, halogens, and inert gases. Draw a dark line to show the separation between metals and nonmetals. Also, draw lines to enclose the metalloids. Colored pencils can be used to distinguish between the families.
