Can anyone explain this? I understand gravity and flow for the vertical
surfaces, but why does the glaze not melt on flat items. I am having the
same problem with low open bowls, glazes not melting or pin holing inside
the bowl, while the outside is almost over fired. Any insight appreciated.
Thanks
