Removing Pressure on the SC Kiln Door Latch

Remove the spring under the top screw to reduce pressure on the door latch.


Removing Pressure on the Silver Clay Kiln Door Latch

Recent Q&As: Firing glass with a manual kiln; programming a cooling segment.


Paragon SC-series silver clay kilns use a spring-loaded door latch. There is a way to reduce the tension on the latch so that opening the door doesn’t jar the kiln. This takes only seconds:

1) Remove the top screw from the latch, which is mounted to the door.

2) Use a toothpick or a small magnetic screwdriver to lift out the spring located under the screw. Save the spring.

3) Reinstall the top latch screw.

Removing the spring eliminates half the pressure on the door latch. The door is easier to open and close yet still has enough spring pressure to stay securely closed.


Q. Is holding temperature with an infinite switch an alternative to a costly controller in glass fusing?

A. Yes, you can fire glass with a manual kiln. The controller is not essential. Paragon's first glass kilns were all equipped with infinite control switches.

The digital controller simplifies glass firings, though, especially if you are using a ceramic kiln. The controller allows you to fire difficult projects such as thick pieces that require days of annealing time.

Q. How do you program a cooling cycle? Programming positive temperatures doesn't make sense for a cooling cycle.

A. Every segment raises or lowers the firing chamber temperature. Instead of thinking of the segment temperature as either positive (heating) or negative (cooling), consider it merely a target. If the segment temperature is higher than the previous segment, the temperature automatically goes up. If the segment temperature is lower than the previous segment, the temperature automatically goes down.


Last week John Watson of Evenheat Kilns died. For many years, we at Paragon had a close relationship with him. In the kiln industry, most of our competitors are also our friends, and John Watson was a prime example of one.

Thank you,
