In the UK, the metal bar used in stirring a coal fire, is a poker.
It is known as a Poker.
A bucking bar is used on the backside of a metal rivet to counter the force of the hammering on the other side.
It's put the pedal to the metal and it means to press down on the accelerator bar in your automobile.
A cook book (e.g. stirring is a reference to the stirring of pots)
Stirring or affecting or moving.

Yes, the metal bar undergoing a color change due to heating in a fire is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties. Heating a metal bar until it glows red hot does not alter its chemical composition.
The magnet bar is used for stirring solutions.
The shiny metal on the back of an electric bar fire helps to reflect heat forwards into the room, increasing the efficiency of the heater. It serves as a heat reflector, directing heat output towards the front of the unit and improving its heating capacity.
A magnetic stirrer is helpful for dissolving solids in liquids. As there are several different appearances, all of them will at least have a base with a speed-controlled spinning magnet inside and an exterior stirring bar. You place the stirring bar into a flask or beaker by tenderly sliding it beside the wall of the container. To avert fracture, don't drop the bar onto the bottom of the container. Place the container on the stirrer base and turn the speed control knob to its lowest set. Use enough speed to start the bar turning in the container. If using exact volumes, as with a volumetric flask, be sure take the measurements before adding the stirring bar.When stirring is finished, keep the stirring bar in the container by draft the liquid into another container. Carefully wash the original container and the stirring bar.
One who pokes., That which pokes or is used in poking, especially a metal bar or rod used in stirring a fire of coals., A poking-stick., The poachard., A game at cards derived from brag, and first played about 1835 in the Southwestern United States., Any imagined frightful object, especially one supposed to haunt the darkness; a bugbear.
This example illustrates the process of heat transfer through conduction, where heat is transferred from the fire through the metal bar to Jimmy's hand. The metal bar acts as a conductor of heat, allowing the energy to flow from the hot end to the cooler end.
Stirring a solution with a metal spatula can lead to contamination due to metal ions leaching into the solution. This can alter the chemical composition of the solution and affect the outcome of the experiment. It is recommended to use glass or plastic stirring rods to prevent such contamination.
You can perform a simple test by bringing a compass close to the metal bar. If the compass needle moves or aligns with the metal bar, then the bar is likely a magnet. Another test involves observing if the metal bar can attract small metal objects like paper clips.
Set the Fire to the Third Bar was created in 2005.
A Class D fire extinguisher is recommended for extinguishing a metal fire.
