I don’t think you can ever melt the glass. It will expand as it heat and shatter long before it reaches it’s melting point…

This seems to melt the TiO2 and cause a molecular bond to the substrate…

Not a good bond, then too much TiO2 or not enough heat…

Under a microscope the TiO2 does look like it’s been melted…
