Zyp Boron Nitride Spray Ceramic Mold Release - 12 Oz

Much prefer this to kiln wash. Glass releases easily. The only drawbacks is that no matter how thoroughly I clean the nozzle, it is always clogged when I go to use it again.

I had been using kiln wash on my ceramic molds when casting glass. It would stick to the glass after firing and had to be sanded off after about four firings and then reapplied. Alot of times the glass would break when trying to get it out of the mold. This stuff is like discovering a miracle! Easy to apply, dries fast and the pieces simply fall out of the mold after firing. The one drawback is having to clean the sprayer nozzle after using. The first time I used it, I decided to skip the cleaning-that was a MISTAKE! Always clean sprayer or apply with a brush. I will be purchasing it again when needed.

Works good

Terrible. It ruined my molds and left residue. I cannot get the remaining substance off my mold, even using an air compressor hose. No good

Works great! More economical than aerosol spray.

Worked better than expected! I had vertical metal posts in a ceramic base for casting jewelry and it worked beautifully.

I bought the manual sprayer rather than aerosol: big mistake. I shook the bottle quite a lot. Nonetheless, the sprayer clogged on my FIRST spray. Took a while to clean out, and I ended up using a brush.

Was pleasantly surprised at how well this product applies compared to the aerosol or similar brush on products. I use it to coat glass molds for fusing. Only takes a couple applications and coats evenly compared to the aerosol version. Despite being an ounce less than the aerosol, you get so much more product this way without the overspray waste. Much better for getting into small areas too.

Love this product and it arrived in good time. Highly Recommend

I followed the directions on the label. I was exact, meticulous and fully followed instructions. The nozzle clogged in 5 seconds. I cleared it with hot water and shaking to remove the sedimentary powder. After that, it sprayed water nicely and was useful on both mist and stream settings. I once again followed the label directions and once again the pump nozzle clogged within 5 seconds. I repeated the process a third time, with the same results. Total dud of a delivery system for what is otherwise a good product. I will have to brush this on my molds, wasting an enormous amount of boron nitride for the area I need to cover. This should be a small pressurized container with a check valve, to ensure that the spray is ejected and no residual particulates can clog the spray nozzle.

Don’t like this form of Zyp. Prefer the aerosol type. Small tube plugs easily and needs to be cleaned after every use.

sprayer wont prime, please send new sprayer asap
