What is the best way to optimize the level of gloss on the underside of draped (mainly) surfaces? When I fire relativey deep coral bowls, it’s the inside that the person really sees vs. the super glossy outer surface. I currently use boron nitride and (usually) fire paper. I oftern see a whitish fog on the inner of surfaces particularly in votives where the glass is stretching more. With bowls it’s more just a dulling of the surpace that I’d like to improve if possible.
