Metal

A precious metal is _________________

an highly valuable element with super and electric and thermal conductivity, high luster, and sensitivity.

Compare and contrast bronze and iron.

Answers may vary, but should be similar to the following: Bronze includes a wide range of copper alloy metals, usually with tin as the main additive. Bronze is a durable metal and is widely used for casting, or pouring melted metal into a mold. Iron is a lustrous, silver, soft metal, taken mostly from iron ore hematite. Like bronze, iron can exist in many alloys. Iron alloys however are usually carbon based rather than copper based.

The ____________ was a stage of prehistoric development in which iron was predominantly used to make tools and weapons.

Iron Age

Define metalworking. Provide a brief history of metalworking.

Answers may vary, but should be similar to the following: Metalworking is the craft of using metal to create different parts, or assemble them together, or larger structures. Metalworking began in the Stone Age. The ancient people knew of seven metals, which were used to fashion tools for hunting, protection, and survival. Metalworking reached new heights during the Bronze Age, which began around 2700 BCE. Later came the Iron Age in the 12th century BCE.

Describe the physical attributes and historical importance of silver.

Answers may vary, but should be similar to the following: Silver is a soft, white, lustrous metal with the highest conductivity of any element. Silver is very ductile and malleable, slightly harder than gold. It can be flattened through hammering or another type of pressure. It can be used to make ornaments, jewelry, and utensils. It has the highest electrical conductivity of all metals.

Bert Lambier The artist used something we would ordinarily think of as a utilitarian object.

______________ is a durable material and is widely used for casting, which is a process by which the melted meteriel is poured into a mold.

Bronze

______________ is not only the most valuable precious metal, but it is also both aesthetically and intrinsically pleasing, and retains religious or symbolic meaning in many cultures.

Gold

Which of the following is true of iron?

It can exist in many alloys, usually with a carbon base.

Which of the following is not true of silver?

It is a copper alloy, usually mixed tin as the main additive.

How has metal been used by civilizations to gain power?

Metal has always been the primary material used by civilizations to make weapons. The amount of metal possessed by a nation can greatly influence how a nation is viewed, feared, and respected by surrounding nations. Metal can be used to create strong weaponry for war, or can serve as a form wealth.

Define metal. Identify the four primary types of metal.

Metal is an element with super and electric and thermal conductivity, high luster, and sensitivity. The four main types of metal are gold, bronze, silver, and iron.

Explain the difference between milling and welding.

Milling is a form of cutting where by a metal is made into to a specified geometry by removing excess material using various kinds of tooling leaving a finished part matching a set of specifications. Welding is a fabrication process which joins two pieces of material. This can be done by either melting the pieces together, or by using pressure in conjunction with heat, or by itself.

Around the year 2700 BCE, which metal was commonly produced?

bronze

What is the image above an example of? What might have been its purpose(s)? How has this type of metalworking changed in both style and meaning, and how does it still serve the same purpose(s)?

The image above is an example of an ancient piece of jewelry. Jewelry was not only for aesthetic purposes in ancient times, but also for spiritual reasons. In ancient times, many people believed that wearing jewelry allowed a person to be spiritually connected to the gods. Today jewelry can still be a form of spiritual connection (Ex: Christian cross, Star of David, etc.), but most people see them as a reminder rather than a way of connecting or a from of protection. Jewelry for the most part is now ornamental.

Early in history, ____________ was created not only for ornamental purposes, but also as a way of connecting to gods and receiving their protection.

metal jewelry

The fabrication method that joins together materials, usually metal, is known as __________.

welding

Explain the processes used in forming metals. Name one occupation in history that has used forming in metalworking.

A collection of processes in which metal is arranged into a desired shape. Most commonly with forming metal, the metal is heated until it reaches liquid form, and is shaped. It will then harden and remain in the shape created. Forming can also include casting, which involving shaping the metal using a hammer or some other form of pressure. Forming has been most commonly used by blacksmiths for centuries.

Describe the physical qualities and importance of gold.

Gold is a highly sought after dense, malleable, shiny, and soft precious metal that has been used as a form of currency for many centuries. It is the most valuable precious metal. It is aesthetically and intrinsically pleasing and has religious or symbolic meaning in many cultures.

Name this statue. What type(s) of metal and metalworking were used to create this statue?

The statue is the Statue of Liberty. This statue is made of a sheeting of pure copper with the exception of the flame of the torch, which is coated in gold leaf.
