Sealing Brick Ceiling

I'm getting a small clamshell oven for roll-ups and whatnot. Trying to prevent IFB particles from falling onto the glass when opening- What can I coat the bricks with, to seal the surfaces?

Replace with fiberboard.

That is an option Paragon offers... At several hundred dollars for the service. I also kinda prefer IFB.

If you want to save money and have a weekend or two to spend working on things, you can build this yourself for comfortably under a grand. Probably more like $500, maybe $600 with hawaii shipping.

If I were back east, with my tools, I would fabricate my own pick up oven. Out here that's not an option, and I'd just like to know if I can slap something on to the bricks so they won't shed. I'd rather not pay an extra 400$ for the fiber board " upgrade"
What's the stuff used to harden fiber blanket? Thanks

Colloidal silica, or alumina is the "Stuff" but it isn't going to do what you want. Stuff is falling since th IFB are deteriorating a bit further in than where the coating is going to penetrate.
Further shipping of those products can't happen as a fluid if it has the potential of freezing.

I think replacing it with a mullite kiln shelf is another option but it would take longer to heat up.

Use a thin sheet of SS.

Charles, this is off topic but, is the DaVinci that just sold the same one that was shown at the Henry in '82?

Not wishing to be obtuse, but a clam shell kiln is not the most ideal set up for roll-ups. You'll have to pluck the plates out with gloves to get them onto the fork, can be done of course, but not the most ideal.
If you haven't already got the kiln have a look at getting a front loading kiln, and even better something with the elements in the ceiling.

I have used a clamshell oven to do small roll ups. It has a SS liner above the glass that is ready to be rolled up.

I have a larger oven that is IFB, with the heater elements inside of quartz tubes, that are above the glass. Forks are Easley used to pull out, if needed.

PS Rich yes. http://www.artguidenw.com/LeoEd.htm

Charles, I thought so, too, but then I saw this. The one at the bottom has the provenance I recall and looks a lot more familiar. Looks like Leonardo couldn't decide if he liked his Jesus cross-eyed or wall-eyed.

Colloidal Silica and powdered zircon are the ingredients of z wash. The zircon does not dissolve so you need to stir it. It may be easier to put on if you turn oven over so roof is flat . Good stuff ... May or not solve your problem, Ceramic shops often carry zircon as an opacifier or to make glazes white. Metal casting shops carry colloidal silica and may sell you a little. I think I would try to get a serous wash on at one time rather than several coats. I have noticed a few times it not wanting to stick to itself.

I've had terrible issues with the 16" paragon clamshell (the one with two handles that opes two ways). If you need reasons not to buy it I'd be happy to elaborate. The clamshells that only open one way are probably much less problematic.

Simply put, brick just doesn't belong in a clamshell. I've since replaced the bricks with fiberboard and am pretty happy with it. Also, blowing out the element channels with compressed air before you heat up helps a lot with brick dust.

I would start with a vacuum with good suction before you go blowing brick dust all over your studio. Wouldn't hurt to vacuum the whole thing.

Mike, if you're dead-set on using the kiln with IFB's, my idea would be to cut-to-fit a sheet of 1" white fiber board and secure with drywall screws (or SS if you're going higher-temps in there) into the soft brick ceiling. Then you could proceed with sealing your ceiling (I love that) with the colloidal alumina.

Id use 2 layers of 2" fiber blanket supported to the ceiling with stainless washers and bolts. then Id hang the elements inside quartz tubes. You could make this conversion in a few hours.

Thanks for the advice. Any product reviews are welcome. It's a lot of money for me, and I can't justify paying $400 for a 14" square of fiberboard "upgrade."
I suppose when the time comes and the bricks are depleted, I'll do the swap out myself.

I've had small IFB glory holes that I've coated with AZS 621 mortar. It worked pretty well. If a small chunk breaks off, recoat the exposed surface.
