Glass etching, or " French embossing ", is a popular technique developed during the mid-1800s that is still widely used in both residential and commercial spaces today. Glass etching comprises the techniques of creating art on the surface of glass by applying acidic, caustic, or abrasive substances. Traditionally this is done after the glass is ...
An example of a glass pattern design by Sakier is the Colony pattern 2412. This pattern was produced in crystal from the 1930s until 1983. It was reissued as Maypole in the 1980s using colored glass. [58] Patterns can be a style of glass, an etching on the glass, or a cutting on the glass.
Only glass products containing at least 24% lead oxide may be referred to as "lead crystal". Products with less lead oxide, or glass products with other metal oxides used in place of lead oxide, must be labeled "crystallin" or "crystal glass". [3] In the United States it is the opposite - glass is defined as "crystal" if it contains only 1% lead.
Etching by Daniel Hopfer, who is believed to have been the first to apply the technique to printmaking. Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. [ 1] In modern manufacturing, other chemicals may be used on ...
Glass brick, also known as glass block, is an architectural element made from glass. The appearance of glass blocks can vary in color, size, texture and form. Glass bricks provide visual obscuration while admitting light. The modern glass block was developed from pre-existing prism lighting principles in the early 1900s to provide natural light ...
Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module in fabrication, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which ...
A clear glass tube is heated over an open flame. It is then inserted into a mold. The glassblower then blows into the end of the tube. The glass expands to fill the mold. The glass takes on the shape of the mold. It is cooled. A silver nitrate solution is swirled about inside the ornament. This gives the ornament a silver glow.
A slurry wall is a civil engineering technique used to build reinforced concrete walls in areas of soft earth close to open water, or with a high groundwater table. [1] This technique is typically used to build diaphragm (water-blocking) walls surrounding tunnels and open cuts, and to lay foundations. Slurry walls are used at Superfund sites to ...
