Dr. Stone Wiki

Flickering Blue Jewel ( (またた) きのブルージュエル Matataki no Burū Jueru) is the fifty-forth chapter of the Dr. Stone manga.

Summary[]

Chrome is excited to have new equipment and wants to go spelunking, stating that he is much better at it than Senku, though the latter points out that they don't need any new minerals. After Chrome insisted, he was sent to look for copper as it's always useful in electronics.

Their attempt at a vacuum tube cracked from the base where the copper leads went through the glass; due to the expansion of the copper wires from heat, causing the glass around them to break. Gen is shook about the level of precision they are dealing with, since the microscopic expansion of the copper led to this, and Kaseki says "as usual, nothing ever goes right on the first try for us" so they set on to work on a solution.

Chrome comes back with a new stash of native copper right when it came handy to carry out the solution they were planning on, which is replacing the wires in the seal with hollow copper tubes which expand inward, removing stress from the glass.

The solution works, but the new issue is that the bamboo filament can't get hot enough for the tube to work in any usable way, vaporizing away. Senku points out that they've hit a dead end, since no resources they have in their primitive world would make a better filament.

The villagers comb through Chrome's collection despite this remark, seemingly to no avail.

Gen takes everyone to see the sunrise of the new year, when a rock found by Suika in Chrome's stash starts glowing blue on the ultraviolet sun rays of dawn. Her discovery is scheelite, a rare ore of Tungsten; a metal with the highest melting point of any.
