Craig,
I feel that learning your clay body is the most important step in deciding
whether to slip and score or not. I always slip and score when fastening
leather hard slabs, an example being the assembly of boxes or trays. When
handling mugs and other ware that is a little softer I usually just use a
small spot of slip from the bottom of the throwing water bucket and don't
score. I used to make over 10,000 mugs a year using this method and never
had handles come loose. If you are not familiar with the clay, then it
would probably be a good idea to slip and score until you have time to
experiment and see what the limits are.
Best regards,
Tim Frederich

I no longer score/slip between the coils of my
sculpture, except between the last coil of the
previous day and the first coil of the next.
Scoring well between work-day sections seems to
reduce cracking at that point, which I attribute
to unequal moisture levels. When the parts to
be joined are of the same dampness, there rarely
seems to be a problem. I try to keep the working
edges of the piece at the right moisture level
for adding to, even while the other parts are
starting to firm up, but it's tough to be exact
about it and the mechanical bond of scoring
seems to help. I use a serrated rib.
