    Thank you for your video. Regarding 5:45, the granulation fusing liquid can be made by adding a copper salt such as copper sulfate or copper carbonate or copper acetate or copper chloride into a plant derived glue such as gum tragacanth, methyl cellulose, or a commercially available product known as "Klyr-Fire". The fusing liquid is used to initially adhere granulation balls or small metal pieces to a metal backing substrate surface. Then from the applied heat of a torch flame, the metal pieces become fused to the substrate. No added solder is required.

    Mika B, the audio got better right after the intro and the rest was quite educational!

    The sound quality is very poor, and the statement that granulation stopped in the late roman period is wrong, a bit more research and you will find plenty of jewellery from the early medieval times too, especially nothern Europe.

      The audio for the first minute is poor, but it's good after that. The part you have issue with, she said it fell out of favor from the late Roman period until the middle ages, a/k/a the medieval period. That means it became popular again after centuries of disuse,

      @@Tiberiotertio She said the practice of granulation ended during the late Roman period and regained popularity during the middle ages. You heard that and chose to ignore it, but then repeated the same thing. Maybe you're just dense. I forgive you.

    Why would you do that to her? To your article? You know darn well we can't hear or understand a garbled word she says for the first full minute. Why send a video out that way? 🙄🙄🙄🙄
