Cristal are fundamentally anisotropic. They are geometrically organized in planes that are denser than other direction. When acid etch a crystal, it began where it's easier, by the planes directions where the atoms are the most distant from each other. This process highlight's the crystal planes.

What is a wooden or metal structure that construction workers stand on?
Scaffold
How do you measure penetration in welding?
To measure penetration of a weld, one must cut and etch the weld, preferably on a test coupon. Etching is just using an acid that will discolor the weld metal so that there is a visible difference between the weld metal and the base metal. Once the acid has taken affect, one can measure the weld using calipers or a similar measuring device.
What materials are used to make an ipod touch?

What is grain flow in forge component?
Grain flow is a typical grain pattern generated during forging of metal. When a piece of metal is cold or hot forged by applying external force or pressure, then metal starts deforming normal to the direction of application of pressure. During the process of permanent deformation, metal grains get deformed & generate what is known as" flow lines ". This is called Grain Flow. It can be seen by chemically etching cross sectional piece of forge metal shown fig below.
Why etchant used in microscopic examination of metal?
In order to reveal the microstructure of the specimen.
What is Metallography?
metallography is the science and art of preparing a metal surface for analysis by grinding,polishing, and etching to reveal it's microstructure constituent
Does dubnium have a crystal like structure?
As a metal dubnium has a crystalline structure but this structure is not known today.
What is etching on paper?
An etching on paper is a print made from a metal plate, called an etching.
How are serial numbers restored in guns?
When a number or letter is STAMPED into metal, it causes a change in the crystal structure in the metal. If someone were to file or grind off a serial number, that change in the crystal is still there. One technique to to polish the metal smooth, warm the metal, and apply an acid to the metal. Where the crystal structure is different, the metal changes color, and the original number becomes visible.
What is the crystal structure of gold?
The crystal structure of gold is that of a face-centered cubic. Gold is a metal element that has an atomic number of 79, and its chemical symbol is Au.
What is the use of acids and bases in metal industry?
it can be used for metal etching
What are the characteristics of pure metal crystals?
Each individual pure metal crystal is characterized by its individual properties. Arrangement of metals in the metal structure is dependent on its characteristics.
What type of structure does sodium possess?
Sodium in its elemental form is a metal. The crystal structure of the metal lattice is body centred cubic where each atom has eight near neighbours. This structure is adopted by all of the group 1 metals.
To ornament metal by etching or by inlaying with gold or silver?
damascene
What is a Leland Brewsaugh metal etching worth?
The value of Leland Brewsaugh metal etching can widely vary. The condition of the item is a big factor. Approximate values are 50 cents a pound if it's nickel plated.
How etching process done?
There are many different etching techniques that can be used such as sandcarving, surface etching, and shading. The you can mix up the different processess and use multiple techniques together. -Eric http://www.glassetchingsecrets.com
