In my opinion, generally epoxy works better than most glues as it is
stays slightly flexible, and ages well. As a aircraft engineer, we use
many types all over large aircraft in composite structures, etc. Epoxy,
due to time cure has the ability to enter the pores for better adhesion
and bonds better. You can get epoxy' in several different types and
curing times, five minutes, one half hour, one hour so on. The longer
the time the better the bond. Some epoxies are heat or light cured, but
these are for special cases.
For years I have been using a FIVE/SIX- Minute clear epoxy for many many
glue together projects (including pottery) with excellent results. When
not completely cured epoxy also cleans up easily with MEK or Lacquer
thinner (watch the fumes please).
I get my epoxy by mail order from Tower Hobbies (www.towerhobbies.com.).
There are several brands available. 8 oz for about $10.00. Will last you
a LONG time. I generally buy the least expensive, as I believe it has
about a one year shelf live for best results. It goes a long way - and
the more you use it, the more things that you will use it for. Right now
I'm using the Tower Hobbies Brand. Mix only enough for what you need to
apply in QUICK time. It starts to harden in a couple of minutes. Also
sometimes in cold Daly City, I use a hair dryer to speed the process. .
P.S. ask for a catalog from tower hobbies - they have a great bunch of
tools that could apply pottery malking..Comments? Sam in Daly City Ca.

Try using PC-7 epoxy. You may find it in the plumbing section of your
local Home Despot. It's the epoxy that old time plumbers used on clay soil
(4" waste) pipes. Works great!
