Acid Etching Now Used in Novel Way to Make Dainty Glassware
Glittering modernistic patterns in pressed glassware, in the form of goblets and vases, are now on the market. The photographs on this page, taken recently in the workshop of a Paris glass-maker, show how such pieces are made.
Sand, the raw material of glass, is melted at a temperature of 1,100 degrees centigrade. In this molten state, it is dropped into a mold that has been carefully designed by artists. A press descends and then rises immediately. The shaped piece is removed from the mold and baked. After it has cooled it is examined for imperfections and if flawless, it is polished on a rotary wheel. Parts that are to remain transparent are coated with Judean tar. Acid makes exposed parts opaque.

Color Names Cause Confusion… A New System is Being Developed to Bring About Definite Standards… Like Sections of Grapefruit
By JOHN H. CRIDER
IN an age when science reproduces with dazzling accuracy the myriad colors of nature, we are inclined to take color for granted. Until related colors are examined closely, side by side, or until someone disagrees with us over the description of a color, we do not worry much about color names. After all, “what’s in a name?”
Hobbyists’ Workbench Folds to Suitcase Size
