This video shows applying glass lacquer to the break-face of a large, fishing-net globe. The reason for applying lacquer to the break-face  is so I can then apply gold.  When clear, non opaque glass is reassembled with mugiurushi you can, unlike ceramic, see the break-face. If you don’t apply gold to it you will see a black line.
