At first, they may be heated by radiation- heat radiated by the fire. As the fire burns, and ashes build up, they will be heated by conduction- heat conducted (poorly) through the ash to the bricks.

Why charcoal does not burn with a flame?

Can painted brick on fireplace be harmful when heated?
Not really, if it is still wet then yes, but otherwise just watch it at the beginning when you light it, to be safe. But it mustn't be that dangerous if it was painted in the first place. I would happily light it.
What are the three ways that igneous rocks form or differ?
Three ways ingenuous rocks form are by magma cooling below, at or beneath the surface. Magma forms when rock is heated, changes composition and/or pressure is released.
What is a side vent?
You may have a "Heatilator" style fireplace. There is a hollow compartment heated by the fire. Cool air is drawn in near floor level, warmed, and leaves for the side vents. Does a much better job of warmng a room than a standard fireplace.
What are the heat transfer from a pot on a metal grill heated over a campfire?
You will have heat transfer to the pot by radiation from the hot coals and by a combination of conduction and convection as the hot gasses of the fire rise to the pot. You might also have some slight heating by conduction from the metal grill to the pot; the grill gets heated the same way as the pot by radiation and flames but may be slightly warmer than the pot since it is closer to the coals and lies between the flames and parts of the pot resting on it. The total heat transfer from the grill to the pot is probably minimal. We would hope that the contents of the pot get heated by the walls of the pot - by conduction and, if they are fluid, convection.
Where did you get bricks from?
they are made from clay that are heated in a high temperature room...

Does burning a fireplace pull warm air out?
Yes, it certainly can. If you have a gas fireplace, I would certainly suggest adding a simple fireplace blower kit. They take the heated air created by your fireplace and force it back into your room. Adding a blower can save you hundreds of dollars a year in energy costs.
What does the focus of a room refer to?
The focus of a room is usually the fireplace. The seating is so arranged that people sitting on a sofa and armchairs are facing the fireplace. it could also mean the focus is a large screen TV, especially if, as in a centrally heated house, there is no fireplace.
Why do gas ovens have the flame at the bottom?
Heat from the flame rises. The stuff below the flame would not be heated. The flame draws combustion air from beneath, by convection. Anything below the flame gets cooled. It's why one puts the kindling paper and wood shavings below the fireplace logs.
What were the marterials used to make bricks?
clay is heated and super cooled into a rock then put together with mortar.
Does carbon monoxide appears only in houses that have fireplace?
It can be a problem in any house that uses natural gas, fuel oil, propane, or a fireplace. Basically if anything is heated with a flame you could have carbon monoxide.
Did they use bricks to build with in the early 1500s?
Yes. Bricks of fire-heated clay have been used since the days of ancient Egypt. Many kinds of bricks and stone were used in the 1500s, both in Europe and in the early Spanish colonies of the New World.
What source of heat was use in the 1800s?
Potatoes would be heated by a fire and use the hot potatoes as warmth.
