Crayons

The second type of eyeliner is a soft crayon, in pencil form, that deUvers mass with minimal pressure. Products of this type may contain as much as 70% talc, 5% pigment, and 5% aluminum stearate. The Hpid portion may include squalene [111-02-4] and alkanolamides.

FIGURE 14.46 An aerogel is a ceramic foam. Its low density and low thermal conductivity, combined with great strength, make it an ideal insulating material. Here a thin piece protects three wax crayons from the heat of a fiame. Aerogels were used to insulate the Mars Rover. 

Marking crayons and inks/paints are some of the oldest methods of applying identification to slabs of rubber whilst being stored prior to incorporation into products or during factory operations. Care must be taken to ensure that the materials used for such identification are compatible with the rubbers on which they are being used. Coloured markers can also contain pigments which may contain active metal ions which could conceivably cause activation of oxidative degradation of the rubber if used extensively.

Preheat temperature shall be checked by use of temperature-indicating crayons, thermocouple pyrometers, or other suitable means to ensure that the temperature specified in the WPS is obtained prior to and maintained during welding. 

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],... 

In plastics, Toluidine Red is practically limited to rigid PVC. Its lightfastness in full shades and slight white reduction is fair. Besides, the pigment is also used to color a number of specific media, such as normal wax crayons and pastel chalks or low-cost watercolors. 

P.R.188 is also employed in paper mass coloration, paper surface coloration, paper pulp, and paper spread-coating formulations, as well as in wallpaper and wax crayons. 

P.O.38 is broad in scope. The list of applications includes special media, such as wax crayons, artists colors, and wood stains, including those that are solvent based. The products are very lightfast (step 7 on the Blue Scale) and fast to overcoating. Blends of P.O.38 with yellow pigments, such as P.Y.83 or P.Y.120, or with carbon black produce useful shades of brown. 

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. 

P.R.208 is also applied in a variety of specialty media besides the three main groups mentioned, such as in crayons and laundry inks, as well as in solvent-based wood stains. Applied onto a surface, these products may safely be overcoated and are resistant towards nitro varnish, acid hardening varnish, and polyester varnish. The lightfastness in these media equals step 7 on the Blue Scale, which is excellent. 

Various disazo condensation pigments are utilized in decorative printing on laminated plastic sheets. They are also applied in a number of special-purpose media outside the above-mentioned groups, such as oil colors for artists and crayons. 

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. 

There are a number of other media which are also pigmented with P.V.23. The list includes office articles and artists colors, such as drawing inks and fiber-tip pen inks, wax crayons, oil paints, and high quality water colors, water- or solvent-based pigmented wood stains, cleaning agents, and mass colored paper. 

The non-medical communicators were still feeding information into the room by walkie-talkie and telephone, and L was still doing most of the work, logging the messages and marking the situation map with a wax crayon.
