The summary of ‘Making purple gold’

The video documents the creator's journey in making purple gold by experimenting with gold and aluminum alloys. Despite initial challenges in achieving the desired purple color and dealing with imperfections such as cracks and oxidation, the creator persists through various refining processes. They successfully create a purple gold bar and mold it into a ring after degassing the mixture to remove hydrogen gas bubbles. The ring-making process faces some setbacks but ultimately results in a unique piece that the creator is satisfied with. The creator expresses gratitude to supporters, mentions their sponsor Opera browser, and wraps up the video by highlighting Opera's features and encouraging viewers to support them on Patreon.

In this segment of the video, the speaker discusses their interest in purple gold, which they discovered was a real gold alloy of gold and aluminum. They express the desire to create a pure purple gold ring, as it was seemingly impossible to find one for purchase. The speaker researches and finds a patent that provides information on making purple gold stronger by altering its composition. Despite the lack of detailed instructions, they decide to attempt making purple gold themselves. The speaker acquires 100 grams of gold for this project, exceeding their original budget.

In this segment of the video, the narrator receives a large bar of gold for a project. To make measuring precise amounts easier, they chemically break down the gold using hydrochloric and nitric acid, creating aqua regia to dissolve the gold. They then reverse the process to turn the dissolved gold back into metallic form, resulting in a fine powder. Finally, they isolate the gold powder by washing and purifying it with various solutions, ensuring the final product is pure.

In this part of the video, the creator refined powdered gold, losing only 0.01g during the process. They combined the gold with 99.995% pure aluminum in a small crucible using a blowtorch. The mixture did not turn purple immediately due to heat. The creator cooled the alloy to allow it to crystallize into a purple color, aiming for an 81% gold and 19% aluminum composition. The resulting alloy still appeared blue due to oxidation, and the creator attempted to extract any hidden purple gold by breaking the alloy open, which proved tougher than expected.

In this segment of the video, the speaker breaks an object to find beautiful purple gold inside, despite expecting a different shade. They follow a recipe from a patent for the process and focus on removing oxides to achieve a shiny ring. By utilizing a tabletop furnace with argon gas, they successfully melt and combine gold and aluminum to create relatively oxide-free purple gold for further processing.

In this segment of the video, the creator attempts to pour out purple gold but faces challenges. The initial pour results in the metal freezing in the crucible. After multiple attempts, the final result is cleaner but not perfectly purple. Sanding reveals silver underneath, leading to confusion about the coloring process. Breaking open the metal piece does show a colored interior, but the color isn’t vibrant. Further attempts still don’t result in the desired purple color. As a final attempt, the creator tries hydrochloric acid to resolve the issue.

In this segment of the video, the creator recounts how they initially struggled to achieve a purple color in their metalwork but discovered a key clue in the patent mentioning heating at 600°C. By preheating a crucible to 600°C, they successfully turned a piece of metal purple, indicating progress in their project. They then attempted to mold the metal into a gold bar shape and refined it through hours of hand sanding and polishing to achieve a final, satisfactory result. The process was challenging but ultimately successful in creating a purple metal piece.

In this part of the video, the creator discusses their process of making a pinkish-purple gold bar and feeling excited initially. However, upon closer inspection, they discover numerous small cracks throughout the bar and uneven coloration. They compare their flawed piece to a purchased pendant, noting the clear difference in quality. Through online research, they discover similarities between their issue and a common problem with pure aluminum caused by hydrogen gas forming bubbles during solidification. The creator realizes that their purple gold bar likely has a similar problem with hydrogen gas causing the small holes and imperfections. They find a photo illustrating the difference in aluminum with and without hydrogen gas, confirming their suspicion.

In this segment of the video, the creator tries to remove hydrogen from aluminum to improve its appearance. After multiple failed attempts with various methods, they decide to bubble Argon gas through the molten metal. They face challenges with finding suitable tubing materials and lose some gold during the process. Finally, they successfully bubble Argon through the molten mixture to remove hydrogen and improve mixing, aiming for a successful outcome in creating a new mold.

In this segment of the video, the speaker describes the process of degassing the gold and aluminum mixture by using a torch, pouring it into a mold, waiting for it to cool down, cleaning it, sanding it, and annealing it. They note a major improvement in the quality of the material, with fewer cracks and holes. The speaker compares the new piece to the old one, noting a significant difference after the degassing step. They address a color issue, attributing it to lighting problems, and achieve clarity by using a polarizer. The speaker is relieved to have finally found a successful method for making purple gold after months of experimentation. The next step in the project is to make a ring, requiring precise sizing due to the non-malleable nature of the purple gold. The speaker decides to create a custom graphite mold using a CNC machine to ensure a perfect fit. Finally, the speaker discusses re-purifying the gold, remelting it, and preparing to make the ring using the graphite mold.

In this segment of the video, the creator describes the process of pouring purple gold into a mold to create a ring. The first attempt fails as the ring cracks during removal from the mold due to shrinkage issues. A second pour partially fills the mold, resulting in a unique shape. The ring is then sanded and polished to create the final piece. Despite initial challenges, the creator is pleased with the result and concludes that working with purple gold was not as difficult as anticipated. Future improvements and experimentation with different methods are mentioned, but the creator expresses fatigue with the process and plans to work on other projects.
