You have to always remember that the numbers with a

0

in front of them are not as hot as the numbers without.
When I first started working with ceramics, without thinking I just figured that

01

and

1

were the same.
It is very important to know what type of clay you are using so that the right Cone is used.
Using the wrong Cone can prove disastrous and expensive for a whole kiln load of ceramics or pottery, and even destroy your kiln.
