History

• Cast iron was initially manufactured in China around the sixth century B.C. It came to Europe around the 12th century. However, cast iron was not common until the 17th century. Cast iron was introduced in 1642 in Massachusetts. The previous form of cast-iron stove burners was composed of smooth rectangular plates that pinned or bolted together to create a boxlike structure. Sand molds, which were used to create cast-iron plates, are still in use today. Basically, molten cast iron is poured onto the mold prior to shaping it.
  
  

Maintenance and Replacement

• A cast-iron stove is structured using a "tongue in groove" foundation. Although cast-iron stoves are more durable than other types, they still require maintenance and sometimes replacement. Replacement may either be for the whole stove or just some parts. Usually, cast-iron burners tend to break or degrade when repeatedly exposed to fire. The extreme temperature of the fire can often melt the cement of the stove, and even change the cast-iron mold over a period of time. Relocation may also cause damage to the stove. At times, when the parts or the whole stove cannot be restored, it's only logical to go for a replacement.
  
  

Replacement Considerations

• Before finding a cast-iron stove replacement, it is important to learn what real cast iron is made of. Ideally, the iron content should be around two-to-four-percent carbon. It's possible to obtain information by contacting representatives of the manufacturing company. A good type of cast iron also includes molybdenum, chromium and nickel. These components help prevent corrosion and make the stove burner even more resistant to water and heat. Most contemporary cast-iron stoves incorporate steel and just one-third cast iron. The kind of cast-iron stove you choose should ultimately have a sufficient amount of cast iron or steel--considering that steel is also composed of iron.
  
  

Replacement Quality

• Cast-iron stoves that have gone through extreme and reliable quality control have the right amount of carbon, iron and other combination of elements. Particularly, it is important to note that the amount of silicon create two distinct kinds of cast iron: white cast iron and gray cast iron. White cast iron contains two percent more silicon than its gray counterpart. Ideally, the gray type of cast iron should be used for stoves. Buyers should take note of these things before making any decision.
  
  

Additional Tips

• Prior to the purchase or selection of the replacement, it is necessary that the whole ensemble be inspected for any cracks, pits and possible rust formation. The airtightness of the stove should also be checked. In cases where the buyer is not as knowledgeable, there should be assistance from an expert. It's also best to check whether oil seeps through the metal or the cast-iron mold. This further helps determine whether there are cracks.
