On the other hand, sealing treatment is performed by immersion in a solution of 1% in pure water.
This can be done by immersing it in a solution of about 100° C. to which sodium metasilicate has been added. If city water is used instead of pure water in the boiling and sealing treatment, the surface of the stranded wire will turn black, which is not preferable.
