where did the vibranium for captain america's shield come from
Wakanda
title: Vibranium text: Vibranium Vibranium () is a fictional metal appearing in American comic books published by Marvel Comics. This fictional metal is noted for its uncanny ability to leverage thermodynamics in absorbing, storing, and releasing kinetic energy in a controlled manner. Vibranium is associated with Black Panther, as his suit is made from vibranium and is found in his native homeland of Wakanda. Antarctic Vibranium or Anti-Metal is created by artificial means, in contrast to natural, or Wakandan, vibranium. Vibranium is also commonly known as one of the materials used to construct Captain America's shield. Vibranium first appeared in "Daredevil" #13 (February title: Vibranium text: form a new tank armor, but was unable to fuse the elements. One morning, he found that the two materials had bonded on their own in an unknown manner. The ultra-resilient alloy was used to create Captain America's shield. MacLain worked for decades (without success) to duplicate the accident. However, during an experiment in the 1960s, he developed the virtually indestructible metal adamantium. In the comics, when T'Challa became king of Wakanda, he strove to end his country's isolation from the rest of the world. Making the existence of vibranium known to the outside world around the mid-1980s, he sold title: Captain America's shield text: The shield is created by a fictional American metallurgist named Myron MacLain, who had been commissioned by the US government to create an indestructible armor material to aid the war effort. MacLain experiments with the indestructible vibration-absorbing metal vibranium. During one of his experiments to fuse vibranium with an experimental iron alloy, MacLain falls asleep and awakens to find that the resulting alloy had set in a tank hatch mold. It was then painted to become Captain America's symbol. MacLain would later attempt to recreate the shield's metal to no avail, his experiments instead eventually yielding the super-metal adamantium. Rogers' title: Myron MacLain text: they were presumably destroyed. The experimental metal used to construct Captain America's shield, it is one of the most impervious metals in the Marvel Universe. While he may have created it by accident and with some luck from the mysterious X-factor, he is mostly known because of its creation. The vibranium composition allows it to absorb vibratory energy as well as kinetic energy directed towards it. Neither he nor anyone else has ever been able to reproduce it, no matter the amount of years, funding, or skills appropriated to such attempts. While not nearly as strong as his first invention, title: Captain America text: which Captain America's 1950s imitator and Nuke are the most notorious examples. Captain America has used multiple shields throughout his history, the most prevalent of which is a nigh-indestructible disc-shaped shield made from an experimental alloy of steel and the fictional vibranium. The shield was cast by American metallurgist Dr. Myron MacLain, who was contracted by the U.S. government, from orders of President Franklin D. Roosevelt, to create an impenetrable substance to use for tanks during World War II. This alloy was created by accident and never duplicated, although efforts to reverse-engineer it resulted in the discovery of adamantium. Captain
