  1. Change the firing style like switch to reduction? That is pretty impossible in my scenario so finding a less toxic clay would be easier for me if it exists. And you're right about kiln fumes being an issue no matter what. I think the extra warnings on some materials just spook me a bit and make me feel like, "Am i doing the safest thing here and is it worth it? "
  2. I know they a make beautiful surface but i am under the impression that the fumes are extremely dangerous compared to some other materials off-gasing in the kiln. So if it's possible to avoid both the dust and the fumes and get similar results then why wouldn't you?
  3. I'm having a hard time finding a speckled clay without manganese. Anyone have any suggestions? I've searched the SDS sheets of Standard Ceramic, Laguna, Minnesota clay co and Amaco. The best I can tell is that Amaco may not use it in their 480M and 48M with grog but their SDS sheets don't seem to list all the ingredients so I'm skeptical. I can't tell from this list (below) what would be causing the blooming speckles? It also seems like they are only listing the top 5 ingredients by weight. Hydrated Aluminium Silicate 10-30% HYDROUS ALUMINIUM SILICATE 10-30% Fireclay 10-30% Hydrous Aluminium Silicate 10-30% silica 5-10% Anyone have any recommendations for a safer speckled clay? Or does that not exist? AMACO 480M STONEWARE W-O GROG - SDS4882.pdf
  4. Thanks everyone. This helps a lot! We have room for a hood and will probably go with the mounted wall bracket. Sounds like it's definitely worth the peace of mind.
  5. 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 kiln atmosphere to run both at the same time? Anyone have experience running both at the same time? I've also read that in order to run the hood vent the kiln lid needs to be cracked? Doesn't that defeat the purpose a bit? Any advice on what is safest is greatly appreciated! Thank you! Angela
