When the soap is completely dissolved, it is allowed to rest for an hour or more, according to the quantity, after which the clear and transparent liquid is put into the frames, in which it will solidify on cooling, When cold the soap is cut into pieces of any required size, and these are moulded in the same way as other toilet soaps. The soap does not, however, acquire its characteristic transparency until after it has been exposed to dry air for a considerable time. To colour the soap red, a strong tincture of archil may be used, and for yellow turmeric may be... 

Review and classification of methods for the acquisition of surface geometry or volumetric descriptions of objects or phenomena with complex optical characteristics (transparent, specular, etc.) can be found in [16]. While the 3D acquisition of opaque surfaces is a weU-smdied problem, transparent, refractive, specular and... 

It is understandable that there is more freedom for the creation of intricate shapes in the thermoplastic temperature range than in the thermoelastic range. However, as a result of biaxial orientation, processing in the thermoelastic range yields products with higher strength, and with better barrier characteristics, transparency, and brilliance. 

Grade Selection Criteria Melt flow characteristics, transparency, suitability for film production, food compatibility. Grades processible by injection moulding, extrusion, blow moulding, extrusion coating and rotational moulding. ... 

Fig. 1. The hthographic process. A substrate is coated with a photosensitive polymer film called a resist. A mask with transparent and opaque areas directs radiation to preselected regions of the resist film. Depending on resist characteristics, exposed or unexposed portions of the film are removed using a developer solvent. The resulting pattern is then transferred to the substrate surface and the resist is stripped.

Transmission Fourier Transform Infrared Spectroscopy. The most straightforward method for the acquisition of in spectra of surface layers is standard transmission spectroscopy (35,36). This approach can only be used for samples which are partially in transparent or which can be diluted with an in transparent medium such as KBr and pressed into a transmissive pellet. The extent to which the in spectral region (typically ca 600 4000 cm ) is available for study depends on the in absorption characteristics of the soHd support material. Transmission ftir spectroscopy is most often used to study surface species on metal oxides. These soHds leave reasonably large spectral windows within which the spectral behavior of the surface species can be viewed. 

SAN resins possess many physical properties desked for thermoplastic appHcations. They are characteristically hard, rigid, and dimensionally stable with load bearing capabiHties. They are also transparent, have high heat distortion temperatures, possess exceUent gloss and chemical resistance, and adapt easily to conventional thermoplastic fabrication techniques (7). 

The unusual resiHence of ionomers combined with ease of processing have resulted in widespread replacement of balata mbber as golf-ball covers. In order to obtain desirable backspin characteristics, low glass-transition ionomer compositions have been developed (10). Transparent coatings on bowling pins promote both longer life and improved playing performance. 

Transparent ionomer coatings are appHed to glass surfaces to improve safety characteristics (39). Special types of ionomers are used as interlayers between glass sheets for appHcations requiring penetration resistance (40). 

A defining characteristic of dyes is the abiUty to dissolve in a given medium. Dissolution leaves no particles to refract or scatter light and thus a dye solution is transparent. A distinct advantage of a soluble-type stain is this transparency and brightness afforded by use of various dye types. SolubiUty is increased by agitation or heat, or a combination of the two. 

These regulations are based in part on the amount of solvents in relation to the amount of soHds. Most wood stains are low soHds materials which rely on their transparency and their abiHty to penetrate and dry fast. Those characteristics themselves put great emphasis on the type of solvents that are used to formulate stains. The low soHds content of wood stains limits the scope of solvent substitution or reformulation. 

Probably the most striking and useful characteristic of common siUcate glass is its transparency to visible light. This transparency results from the absence of grain boundaries and delocalized electrons, which tend to scatter and absorb light. 

The introduction of a second heteroatom (other than sulfur) does not change drastically the absorption characteristics of small heterocycles. Oxaziridine and diaziridine are still transparent to light of wavelengths above 220 nm (Section 5.08.2.3.2).
