Using Mercury to clean lead from a gun barrel is not recommended due to safety and environmental concerns. While mercury can theoretically bind with lead and help remove it, the toxic nature of mercury poses significant health risks to the user and potential environmental hazards. Safer and more effective methods for cleaning lead from gun barrels involve using specialized cleaning solvents and tools designed for that purpose. Always prioritize safety and utilize appropriate cleaning techniques for firearms.
To effectively clean a mechanical pencil using a cleaning rod, first remove the lead and eraser. Insert the cleaning rod into the pencil barrel and twist it to remove any debris or blockages. Repeat this process until the pencil is clean.
Breaking a mercury thermometer can be harmful as mercury is toxic. It is important to clean it up carefully using gloves and avoid touching the mercury with bare hands. If mercury is ingested, inhaled, or comes into contact with skin, it can lead to health issues, so it's best to contact a professional for cleanup.
I have no personal experience with this. What follows is information from a reputable local gun dealer. Rifled barrels are designed primarily for use with sabot slugs. Buckshot will not harm a rifled barrel because in the barrel, the plastic wadding holding the shot together will be the only portion of the projectile(s) in contact with the barrel. Firing rifled lead slugs will lead to difficult (nearly impossible) to clean out accumulations of lead in the barrel & negate the rifling because the rifling of the slug & the rifling of the barrel will not match up.
Lead will sink in liquid mercury because lead is denser than mercury. Mercury is a heavy liquid metal, so most metals will sink when placed in it.
It is dangerous because it can cause mercury poisoning. It can lead to damage of the brain, lungs, and kidney. As reffered to with the mad hatter in Alice in wonderland
Lead would float in mercury, as it is slightly less dense. (11.3 g/cc for lead, 13.5 g/cc for mercury)
Is there a question there? If you are asking what to do, the best thing is probably to have a gunsmith remove it.
Assuming you mean a barrel that is for lead pellets, if the barrel is not rifled, steel shot will not damage the smooth barrel. If it is rifled however, steel shot will in fact damage the rifling.
Atomically, no. Mercury's atomic weight is 200.59 whereas Lead's atomic weight is 207.2. So basically, if you had the exact same amount of Lead and Mercury, lead is heavier.
Depends on the age of the barrel
actually you can still extract lead from lead oxide, but you need to do this experiment with carbon or other reducing agent e.g. hydrogen and with a high temperature Celsius. But the reason that you can extract the mercury from the mercury oxides exactly is the higher reactivity of the lead. higher the reactivity means more difficult to extract the metals from the ore. so it is possible for lead to extract it from the lead oxide
Firing lead shot through a slug barrel will not damage the barrel. The rifling will distort the shot pattern and you will get less than desireable results.
