Mantlepiece and grate styles have altered however the basic structural elements of a fireplace haven't drastically changed for centuries. The combination of a big stone or brick beginning with a fireplace built over it changed from the evident fact that smoke rises, instead of from a scientific understanding of how a well-designed flue system works. Subsequently early wood and later coal-burning fires were quite inefficient and it wasn't until a specific Benjamin Thompson (also called Count Rumford) produced his thesis on the principles of hearth style in 1799 that smaller grates and changes in the inner form of the openings were released. My family friend discovered antique fireplaces by browsing books in the library. A brick or stone enclosure forms the basis of-the fire. Variously referred to as the fireplace opening or break or contractors opening, it may be set flush with the wall or built out to the room, forming a chimney breast. That chimney chest increases through the height of the home, rising through the ceiling to make a chimney stack. At the top of the beginning the gather and flue combine to transport the smoke up the chimney. When the chimney is shared by several fireplaces on different floors, it might contain multiple flue. The masonry within the fireplace opening is supported by way of a lintel or perhaps a stone arch. Old inglenook fire-places used huge oak beams, whereas a powerful iron strap generally supports an early brick arch. Later fire-places might have a right arc supported by angle iron, and by the twentieth-century cast concrete lintels were standard. A fireplace, made from non-combustible materials including stone or tile-faced cement, projects out to the room to protect the floor from ashes. In many old houses the hearth was set flush with the floor, though sometimes a superimposed one was used to boost the amount. The space within the fireplace opening, known as the hearth, is usually level using the hearth itself. Your dog grate for burning wood or coal can be added to this straight back hearth. But, from the mid-nineteenth century the mass-produced cast-iron sign-up grate which filled the opening, had become the style. To perform the construction, a mantelpiece or mantel or fireplace surround, as it is usually called to-day is suited to shape the grate or fireplace opening. The mantel could be made of stone, standing, marble, wood or cast iron. The walls around it might be finished with wood paneling, or even more frequently with plaster, and in some cases the mantel extends upwards to form an impressive chimneypiece. Mirrored overmantels were introduced in the late eighteenth-century, and these became the traditional feature of Victorian sitting areas. Within this hearth an open fire burning wood or coal is a happy view, but if it is your only way to obtain warmth, as it was for years and years, this romantic image may quickly fade especially if the fire does not burn properly. Finding a fire started and retaining it alight then becomes difficult, if not a chore. For coal and wood fires to burn well a good method of getting air is required under the grate, as well as a method of escape for the hot gases and smoke. Using the fuel properly contained inside the fireplace opening on a grate, free circulation of air is possible and waste ash may fall through the grate so the fire isn't stifled. If the chimney is limited or the flow of air is restricted the fire will not function efficiently..
