I keep a tub of slip wipped from my throwing of bowls or larger pots-mix a little vinegar with it now and then . (this is all with porcelain)
Use a metal serated tool for most handle attachments. I score then slip and handle-no eatra water.This is on about 98% of all attachments.I try to make this connection only when the clay is just right mositure wise.
For some reason with teapots I slip then score then slip then attach-maybe I think twice will be better.
I cover all work one night with loose plastic then dry with plastic off usually pretty fast.
