Desert MAR COMERS AL @TNGNG. Delica White Best Glass itor Light Catalogue Naso Now doing the business formerly conducted by PITTSBURGH LAMP, ERASS & GLASS COMPANY at Swissvale, Pa. T IS our pleasure to present to you in this Catalogue, illustra- tions of our line of LIGHTING UNITS. Our Units have been scientifically designed to give the most light, with proper diffusion, for given wattage. They are beautiful in appearance and at the same time yield the highest degree of efficiency. In the wide range of shapes and sizes in which these Units are made, we offer to the trade a Lighting Unit for every purpose— Plain Units in single Glass, our Superior NICCO OPAL Glass, for Commercial and Industrial lighting, and the more graceful shapes in Cased Glasses—DELICA WHITE and DEL IVORY, with various decorative effects to meet the requirements for any artistic interiors or Public Buildings. It is the policy of the KOPP GLASS, INC., to make a product of quality and merit rather than inferior merchandise at lower prices. Considering the efficiency and service obtained from our Units we believe that in the end they will prove to be the most economical. Our position today in the Lighting Field is not attributable to any special privilege or secret process but rather to the intelligent application of skill and useful knowledge of Glassmaker’s art and chemistry gained from many years of practical experience and untiring efforts. We also manufacture Decorative Shades for Residential Light- ing and special uses, illustrated in our Catalogue No. 32. Elec- troliers and Torcheres—Catalogue No. 33. If interested in these lines we will be glad to forward Catalogues on request. “kK. Gol.” Aims to SATISEY. KOPP GLASS, INC. -@ Kopp 6148s Inc. SwissvALK,Pa._ DELICA WHITE CASED GLASS DEL IVORY CASED GLASS NICCO OPAL GLASS N THE opposite page you will find illustrated various shapes and decorative effects in our line of LIGHTING UNITS, representing modern French as well as classic ideas in Decorations, some of which are quite a departure from the usual run of Units. Certain Units are designed for special purposes, such as our— BRILLIANT UNIT, illustrated on Page 4, of this Catalogue. This Unit is recommended for Jewelry Stores, Restaurants and Display Rooms— it has found immediate reception wherever shown. DELICA WHITE CASED GLASS On account of the process employed in making DELICA WHITE CASED GLASS, viz., that of casing or spreading a fine film of high grade Pure White Glass over a main body of Crystal Glass, we obtain a Glass of greatest diffusion and smallest absorption, with a highly polished surface. A simple test to show the delicacy of this Glass is to lay a piece of printed matter against the inner surface of the Glass and you will note that it can be easily read, which cannot be done with other Glasses. DEL IVORY CASED GLASS This Glass is made by the same process as the Delica White Glass, the fine film being of a light Ecru Color Glass, producing a beautiful Ivory color. This Glass is more for decorative effect where a strong light is not desired—is most suitable for Hospitals, Churches and special effects in interiors. NICCO OPAL GLASS Our NICCO OPAL Glass is also a Glass of special merit and should not be confused with ordinary Opal Glass. It is also the result of years of experiments and we do not hesitate to say that it is the strongest Glass on the market today. Besides having a low absorption and good diffu- sion it will also withstand various changes in temperature, and has proven highly satisfactory in places where Glass is exposed to changes of the elements. We believe a trial of this Glass will convince you of the superiority we claim for it. , a] 2 Ib @- Korr_Gtiass Inc, SwiISsvaLk.Pa.
