Hi Val
I checked the Orton web site to be sure, and they say it is fine. You can read the questions and answers below.
-------------------------
Problem
Can a box of cones become too old?
Potential Cause
Cones have been in storage for many years.
Possible Solution
No. Cones do not change with age. At Orton we have Pyrometric cones over 25 years old that we use for comparison
testing and standardization. We do keep improving cones, though. Today’s cones are more uniform and perform better
and more consistently than those we made 5, 10, or 50 years ago. Also, some changes occur when the supplier of our
raw materials goes out of business.
--------------------------
Problem
The cones became wet. Can they still be used?
Potential Cause
Sitting in a flooded basement or exposed to high humidity.
Possible Solution
Cones are not normally affected by usual amounts of moisture such as humidity in the air. If the cones are damp it
is best to dry them out before use. If the cones have been extremely wet they should not be used. An example of this
might be cones that were in a flooded basement or studio. These cones may have retained their shape but they may
have lost their strength and can possibly break off in the Kiln-Sitter® if they are small cones. The large cones
that have been wet may not deform with the proper accuracy.

I just bought out a ceramic business and I got many boxes of cones.
Now they are probably old but do they lose their
"goodness"...LOL...could I still use them?
Thanks for any help you can give me.
