So, I'm loading our glaze kiln (Skutt 1231 PK) 31 inches tall, 28 wide, 11.5 cubic foot firing chamber. And the kiln slides on the floor. Now it's on casters, but the casters are suppose to be locked down, and even if they aren't the Envirovent coupler is spring loaded and should drag on the floor... Weird!?!
So, I get down on the floor to inspect this oddity, and find... what do I find? The Envirovent coupler is disconnected, not engaged, laying on it's side far away from the vent holes in the floor of the kiln. Meaning we have been firing our kilns unvented. How long? Unknown. Did I say Kilns? Well, me rolls over to inspect Meshach (Our glaze kiln is called Shadrach). Meshach, who does most of our bisque firings is... What's this? Disconnected as well?!? I have no idea how the couplers became disconnected as they are spring loaded and the spring is fairly hefty.
So, this means both glaze and bisque have been fired unvented! What are the implications of unvented firing? How might an unvented firing manifest its self in glaze faults? We've been having a series of faults, and now I'm wondering if I might have found the problem...
Your thoughts, other than... Go post this in the thread on "It's OK to make mistakes!" :-)
