Mark C. Posted September 4, 2012 Report Share Posted September 4, 2012 Hi Mark, I actually found this post on my first try, from the last time we discussed this on clayart. the quote below is to the best of my memory from John Britt: REMET Corporation 301 Turner Street Utica NY 13502 Contact: Ed or John Phone: 315-797-1845 Scott Martin - Inside Sales REMET Corporation Phone: (800) 445-2424 ext 277 Fax: (315) 797-4848 smartin@remet.com I have used it for mending jobs. This note below on clayart late '06 that sent me looking for it. I used it mixed with EPK to glue kaoboard pieces together. Best, Eleanora Please note, you all! The most effective "RIGIDIZER" for any application using ceramic fiber is "collidial silica" which is produced through ionization of "sodium siclica" I have used clear liquid collidal silica for endless applications for more than 4 decades. For example, one of my electric kiln lids, started to crack. I simple applied collicial silica into the crack; after the next firing, Bingo! The lid is repaired totally, no more cracking or shifting movement of the kiln lid. I could do an entire list of related applications. Yes milled zircon is zircopax-just ground up more. This coating will work well with coating kao-board I use it at cone 11 on brick and fiber Where did you get your gallon of colloidal silica? Laguna Clay Co. sells milled zircon as well.

I bought a gallon of colloidal silica a few years ago and have used a tiny bit of it combined with I think kaolin and flint for a surface treatment and as a glue. I will be trying your recipe very soon. I googled zircon powder and it seems it is zircopax. Correct? I have lots of things to use this on but my most immediate quest is for a better kiln wash for glass. Especially my little kao-board microwave glass cooker. I coated the outside with itc 200 (I think) immediately as the outsides seemed to degrade when you look at it, and that has worked very well indeed. Now I want a better coating for the firing surface. I hate firing on the kaowool paper and have been using regular kiln wash but that doesn't stick worth squat. I bet this will work very well. Am just putting in a ^04 kiln firing and am thinking of making up a tiny bit, applying it to a scrap of kao-board, and seeing how it goes. Any comments? Thanks, Eleanora I agree with Mel's post on ITC-really great stuff-I have used it a bunch Here is another coating that I have use a lot as well. This stuff sticks and stays stays put even in fireboxes. I got this recipe from a glassblower who coated his glory hole of soft brick and fiber and have coated both with it with good results. Liquid COLLOIDAL SILICA mixed with milled ZIRCON 1 gallon is plenty of the liquid is plenty to buy. start out by vacuuming kiln then spray all soft brick with water via a mister bottle so its slightly damp. if its warm out only do the area ahead of your application. Start with a small say cereal bowl 1/2 full of colloidcal silica about 3/4 cup -This will be your learning curve batch- add milled zircon powder to this until its like heavy cream (this liquid absorbs a huge amount of powder)-use a wider brush and apply a coat to damp area bricks- coat kiln -let dry then bisque fire. This mix works as the best coating I have ever seen or used-Its a bit hard to brush and will ruin your bowl and brush but will stick to just about anything-It can be sprayed as well. Work it into all cracks as its acts like a glue as well. Use a respirator when spraying. It covers my soft bricks and rarely spalls (comes off) You will not find this pre made and must make your own from scratch. Good luck-this stuff works. Its about 100% better than any other wash you may want to apply to a kiln. These ingredients are a bit harder to find but worth it.I still use and like ITC but this stuff also has its place.
