Some manufacturers have altered the appearance of the traditional cast-iron stove by applying different materials to the outside of the stove. Stoves are frequently enameled in a variety of colors and some are covered with marble or porcelain. Cast-iron stoves are made of cast parts bolted together. The parts should have detailed lines and clean surfaces free of grains. The characteristics of steel and cast iron are not significantly different, therefore you can make your choice based on size , budget and the design of the stove.
Most stoves also have firebricks or metal plates to prevent burnout.
Stoves may have doors on the top, on the side, or both. Many of the new wood stoves have large glass doors on the side so that you can see the flames. Some glass doors perform better than others. For example, one type uses an infra-red barrier in the glass that reflects heat back into the firebox. Some new models have airflow systems that remove soot and smoke from the glass doors, making them virtually self-cleaning.
