Slump for folder pendant
Longer, lower and slower is always the best answer – except when it isn’t
I would try and go longer – and only increase the temp if it takes unreasonably long at the lower temperature.
It has slumped enough if the folder-over section leans forward when set up for the second slump – otherwise it can fall backwards and not close the hole.
Hope this helps.
