Kiln Maintenance Day

Today is Kiln Maintenance Day. Not a fun task, but essential every now and again. The batt wash on my shelves is the stuff that came with the kiln, and when I put it on, I had no idea what I was doing. It was mixed too thick, and applied too thick, and left an awful mess when it started cracking and flaking, and has just got worse and worse. So, since we just bought a few new shelves that needed a fresh coat of batt wash, I decided to refurbish our existing shelves too.

The new batt wash is a zircon based batt wash (from Scotclay) and it paints on beautifully. I have this on a small shelf that I’ve been using for about a year, and there is not a flake or chip in sight, so I’m looking forward to many years of use before I have to do this horrible job again!

Essential safety equipment!  Nasty stuff coming off of these shelves, not good for your lungs, so a respirator is essential, as are safety glasses (or, in my case, glasses)
