My house was built in 1890, with stone basement walls, so it would be messy but can be done. Maybe I can figure out a way to mount to the joists up above. Hmmmm, got me thinking now. Maybe attach the motor to a piece of 3/4 plywood and screw into the joists.

Thank you for the responses! I like the angle bracket mounting idea.

Hi! I'm upgrading the vent system on my kiln and got an Envirovent 2. It is meant to be installed with the motor mounted to the wall, at the end of the ducts. I don't think I can do this because my kiln is in a basement. I need to get good and high to vent out between the joists that sit on big old stone walls. I don't think it will work to mount the vent way up between the joists. The manual says you can mount the motor on the floor and then use more ducts to direct the exhaust outside, but that it will no longer act as a negative pressure system. Has anyone done this or something like it? It just isn't going to work as well? My current old vent has the motor positioned underneath the kiln and has worked ok, though not perfectly. Thank you!

Hi all, just wanted to follow up for posterity and with gratitude. I followed the advice to Dremel the chunks and and dab to fill and it worked pretty nicely. Difficult to reapply a consistent amount of glaze, but it's good enough. As to the root of the problem, I re-sieved and did something I've never done before: cleaned out the glaze bucket. I always sieve back and forth, ending up in the old bucket that has 5 years of crust all along the sides. This time I cleaned all the crusted glaze off. I suppose I could have scraped and mixed it in well, breaking up chunks and I may do that in the future. Cheers!

I seived back and forth between two buckets three times, mixed with remnants from the last batch. I didn't spend much time mixing before seiving and maybe that's where I went wrong. I tried to use some 120 frit sandpaper and hand sand one down and it barely scratched it. Dremel is definitely the way to go. Thanks for that tip!

The bisque was sponged and rinsed before glazing to clean out dusty matter, and was glazed an hour or two after cleaning. This particular piece is a cup. The chunks are on the inside vertical wall, not just on the bottom. Does that point to it not being kilnwash? The shelves do not have kiln wash on the bottom. Chunks were even in the ware in the top shelf, which did not have a shelf above. That points to it being in the glaze, I'd think. I do remember when seiving that there were some larger gritty particles.

That kinda makes sense. Some of the chunks are big enough that there's no way they passed the seive.

Hi! I just unloaded a kiln and I have that sinking feeling we all know. I had mixed glaze prior to this firing, the same glaze I've been using for about 5 years. There are small white bits in the glaze, I'm fairly certain that it is an undissolved ingredient. It is uniformly distributed across most of the pots in the kiln. I seived the glaze 3 times in mixing. The seive is mesh 60, but was sold as a glaze seive. Now I'm seeing that glaze should be mixed with a 80-100 mesh seive. That's frustrating. I haven't had this problem before. Two questions: 1. How can I keep this from happening again and salvage the bucket of glaze I just made with crazy expensive tin oxide? Should I get a different seive? 2. Anything I can do to salvage this kiln load? Is it a bad idea to just sand down the bits? I can't provide them to customers like this. Thank you!
