Hi All, I work in the same room as our kiln and my husband and I are hoping to be pregnant soon so I'm looking into every possible way to reduce hazards in the studio. Controlling what materials I use is an easy fix but preventing toxic gases from leaking out of the kiln is my biggest concern (even if most firings take place overnight when I'm not around). Our kiln is already equipped with a downdraft vent but I wonder if it is as effective as an overhead hood vent? Is it overkill to do both at once? Would running both at the same time work against each other? Does it change the kil
Hi Guys, I have a small test kiln from paragon that has one peep hole and no vent. Everyone that I have contacted says that small test kilns don't need to be vented, just prop the lid open for the first few hours of firing and then close it. I have not had any success with this. I tried keeping it propped open until it reaches 1400 degrees, however it never reaches that temperature probably because the heat is escaping. It's mainly affecting my red glazes right now, however all of my glazes come out very dark and the red ones look burnt and brown ALL the time. After doing a lot of r
When I am firing my electric kiln, I start with the lid propped open about 2 inches and the top peephole out. Then at around 1000 degrees F I shut the lid. The top peephole is open the whole time. I understand that the lid needs to be propped to allow moisture and gasses to escape in the early stages of firing. My questions are: 1) is 1000F an appropriate temp to close the lid? 2) Is it necessary to prop the lid on a ^6 glaze firing as well as the bisque, or only during the bisque (^06) I have been firing this way for a couple years and the pots always come out well. However the lid has
