Design Considerations for Venturi Burners
As a rule of thumb, a single Venturi pipe burner should have head space equal to approximately two times the diameter of 1the burner pipe. For multiple burners, add /2" of head space for each additional burner pipe. For standard Venturi ring burners, head space should equal approximately 75% of the ring burner's outside diameter. These ...

Understanding Kilns
Preheat the Kiln. Preheating the kiln before placing pottery or ceramic pieces inside helps prevent thermal shock and ensures a more controlled firing process. Gradually increase the temperature to the desired firing temperature over a period of time to allow the kiln and elements to expand and stabilize.
