Why in the world is this blade on fire?

I had one of those days where I ended up spending far longer watching videos about a topic I never knew I'd be interested in. Today's topic: the famous Viking sword...the Ulfbehrt!
Basically, I saw this gif on reddit, and just really needed to know what part of the sword making process would need the blade to be on fire like that--apparently, it's called quenching, but I wanted to know more.
If you just want to see the gif section, it runs from 46:04 to 46:40 in the video above, but I somehow ended up watching the whole thing (and this wasn't exactly the most thrilling documentary...)
BUT! I was able to learn why it looked so badass in the original gif: we're seeing the smith cool down the sword very, very quickly in an oil-bath to harden the steel. Oil baths are heated to a higher temperature than water, which means the blade can cool slower at first. Different quenchants (apparently that is what you call the liquid used to cool blades during the quenching in) are used for different steels to impart specific internal structures that make the steel hard and flexible.
Sadly, I don't think they usually pull the sword out of the oil early and let it flame like this (for safety reasons). Blades shouldn't be removed from the quenchant (lol this work just kills me every time) until they are below the flash point of the oil. Still, I'm glad they did for the video because it's pretty cool!!
I honestly don't know why I'm writing this card but I thought it was pretty cool and you might too so hey hi hello if you're into this kind of stuff come hang out in the comments XD
that's interesting! i want one now lol

The Power of Change: How the U.S. Renamed 4 Places To Erase Racist Slurs For A Native Woman
In 2020, the U.S. took a powerful step forward in the fight against racism by renaming four places that had been named after a Native American woman, which were derogatory slurs. This gesture was a powerful symbol of the power of change and the commitment of the U.S. to fight racism. In a world that is often divided by race and ethnicity, this move was an important reminder that we could all come together and make a difference. It is a testament to the impact a single person can have on the world and the potential for change within all of us. The four places that were renamed were a park, a lake, a mountain, a mountain range, and a valley. Each of these places was given a new name that honors the Native American woman who inspired the change. The new names not only reflect her strength and courage but also serve to remind us of the importance of respecting and celebrating diversity. What were the four places renamed? The four places that were renamed as a result of this effort were: - The Lake and Park in California, which were once named after a racist slur, was renamed to reflect the name of the original Native American inhabitant who lived there. - The mountain range in Colorado that was once named after a racist slur was renamed to reflect the name of the Native American woman for whom it was being renamed. - The valley in Colorado that was once named after a racist slur was renamed to reflect the name of the Native American woman for whom it was being renamed. - The mountain in New Hampshire that was once named after a racist slur was renamed to reflect the name of the Native American woman for whom it was being renamed. What were the old names, and what are the new names? - The Lake and Park in California, which was once known as Lake Merced and Merced Park, were once named after a slur that was used to describe Native Americans. The new names reflect the original inhabitant of the area, the Aul and Elu. - The mountain range in Colorado, which was once known as the San Juan Mountains, was once named after a slur that was used to describe Native Americans. The new names reflect the original inhabitant of the area, the Colorado Rockies. - The valley in Colorado, which was once known as the San Luis Valley, was once named after a slur that was used to describe Native Americans. The new names reflect the original inhabitant of the area, the Colorado Valley. - The mountain in New Hampshire that was once known as Mount Jefferson was once named after a slur that was used to describe Native Americans. The new names reflect the original inhabitant of the area, the New Hampshire Highlands. The impact of the renaming By changing the names of these places and reflecting the names of their original inhabitants, the U.S. was able to take a powerful step forward in the fight against racism. This gesture was a powerful symbol of the power of change and the commitment of the U.S. to fight racism and discrimination. It was a powerful reminder that we could all come together and make a difference, regardless of our differences. The renaming of these places was a powerful way to recognize the strength and courage of the Native American woman who inspired the change. It also served as a reminder of the importance of respecting and celebrating diversity. How this gesture reflects the power of change The journey to change the names of these places began with the efforts of a Native American woman named Mary Rowland, who was a descendant of the Aul and Elu, the original inhabitants of the Lake and Park in California. She was distressed that places that were important to her people had been named after a slur that was used to describe them. Rowland reached out to her local congressman, and with his help, she was able to start a campaign to change the names of these places. The impact of her efforts was not limited to her community but extended to the entire country, inspiring others to follow her example. Other communities also took up this challenge and lobbied for the renaming of places that had been named after a slur. This campaign culminated in 2020 when the U.S. government chose to make this gesture at the federal level. How this renaming is a reminder of the potential for change within all of us This renaming of places that were once named after a slur serves as a reminder of our capacity for change. It is a testament to the power of one person to make a difference and the potential for change that is within all of us. In the words of Mary Rowland, the woman who inspired this renaming, we all have the power to make a difference. It is a reminder of our ability to learn from the past and create a better future. It demonstrates that we can all come together and make a difference, regardless of our differences. It shows that no matter who we are or what challenges we face, each of us has the potential to make a difference in the world. Conclusion This renaming of four places that had been named after a derogatory slur was a powerful gesture that was a powerful symbol of the power of change. This was a powerful way to recognize the strength and courage of the Native American woman who inspired the change.

What Is Black Powder
Black powder is a low explosive substance made of charcoal, sulfur, and potassium nitrate (saltpeter). It is employed in some ammunition and muzzleloaders in addition to being a propellant in fireworks and pyrotechnics. In general, purchasing black powder necessitates a federal explosives license or authorization under the federal explosives laws at 27 CFR, Part 555. However, black powder is excluded from these laws according to 27 CFR Part 555.141(b): -That is commercially manufactured. -In quantities not exceeding 50 pounds. -Is intended to be used solely for the sporting, recreational or cultural purposes in antique firearms or antique devices. For the above-mentioned uses in antique firearms or antique devices, commercially made black powder may be purchased and used in quantities not to exceed 50 pounds without the need for a federal explosives license or permit. If a person produces black powder for their own individual, non-commercial use and it is not a "commercial" product within the meaning of the exemption, they do not need a manufacturer's license. However, the black powder created must be handled in accordance with the relevant legislation. Additionally, anyone planning to carry any black powder that does not fit the aforementioned criteria for exemption or who plans to purchase any amount of black powder for any other reason, such as for use in fireworks or pyrotechnics, is required to get a federal explosives license or permit. Additionally, these people are required to keep the black powder in an explosives magazine that complies with Part 555 standards. People that manufacture, import, or deal in any volume of black powder are not covered by the exemption. Therefore, these individuals are required to acquire a federal explosives license, store the black powder in line with rules, and keep track of their purchases and disposals. Recall that black powder that does not satisfy the requirements for exemption in 27 CFR 555.141(b) is considered a low explosive under 27 CFR 555.202 and may be kept in type 1, type 2, or type 4 magazines, as well as in type 3 magazines for temporary attended storage. Explosive items must be moved to type 1, type 2, or type 4 magazines for unattended storage rather than being left in type 3 magazines (day boxes). No dwelling or residence shall be used as an explosives magazine, and no building shall be used to store more than fifty pounds of explosives. Security Awareness Retail staff members who sell black powder should be aware that these components could be utilized in bombs. Black powder dealers are strongly encouraged to build ties with their local law enforcement agencies by the ATF, FBI, and DHS. We advise that industry participants include reporting suspicious activity and being aware of it in official employee training programs.
