Remember when I reviewed the RZ mask?
A potter friend of mine bought one and sent me an e-mail stating that his mask came with a warning that it didn't filter silica... the main hazard in pottery. I looked through the packaging that came with my mask and didn't see anything with that type of warning. Before my review I e-mailed the company and asked what size micron it would filter and they said .1.
Potter Emily Murphy was also contacted by the RZ Mask and asked to give a review, which she did. Since that time she also was made aware of the company's new warning label and you can read the update to her review here.
I find it unfortunate that the RZ Mask has been unresponsive to her, and other potters questions. I plan to e-mail the company to see if I can get a response. If the mask isn't suitable for ceramics just say so! I felt it was important to share this new information with readers.

behind the scenes...
Throwing pots is so enjoyable and fun, and yes, it is like Christmas morning every time a kiln is unloaded... but there is so much more work that needs to get done in order to have those fun times.
Like grinding and washing kiln shelves.
We have been lazy about that since moving to Seagrove. My NH kiln was much larger than our new one so I had lots of extra shelves... then add Jeff's kiln furniture to the mix and I think you get my point. Unload the kiln... oops a stuck pot, set the shelf aside. No need to grind and clean right away, we have LOTS of shelves!
**warning - if you have been firing kilns for years, you may find this post boring - newbies might learn something**
Eventually the time comes when the job HAS to get done. We need to fire the kiln and we're going to be short on shelves. We are having great weather so we set up our work outside. Jeff did all the grinding (electric side grinder) while I mixed up the kiln wash. We use equal parts silica and kaolin, mix well and add enough water so it is thick like brush-able slip.
Some of our shelves were left with craters after grinding
I went over all the scarred areas and applied kiln wash with a brush, trying to fill in the craters.
Since we had so many shelves to do, we decided to apply the kiln wash with a roller. It was fast and we are hoping there will be less flaking after firing.
Look at how pretty they look now!
We let them dry overnight and today we will wipe the edges with a sponge so that we don't get any stray wash falling into the pots as we fire.
Today is loading day, we have lots of pots glazed and ready to go... back to the FUN stuff!
