zyp coating

Formally known as mr97.
Has anyone used it instead of kiln wash on a shelf for fusing?

Why would you want to?

[jim simmons]

Hi Brad.
Because I have developed a bad shoulder that prevents me from lifting anything heavy.
My mullite shelves are just to heavy to lift to scrape and lift out of the kiln.

Sorry about your shoulder. Having just turned 65, I can certainly sympathize.

I haven't tried ZYP on the shelf, but am not sure how it would hold up to repeated firings. I guess I would just use thinfire or Papyrus, easy enough and you can vacuum it out as needed. But you can always try the ZYP and see how it holds up. One thing I don't like is that it's irreversible without sandblasting it off.

Hi Brad
The other reason is that I am wanting to try a couple of techniques that thin fire won't work with.
These are some stack firings that consist of stacking 13 layers of glass and then have them spread out.
I am afraid that thinfire would get embedded in the bottom layer.
And because I don't have a sandblaster, it would become a part of the "design". :>)
66? you are just a young pup. My shoulder started to bother me when I was around70 and has just gotten worse.
*85 and counting :>)

Great, something to look forward to.

my experience with all the coatings was mixed. The lower temperatures worked better. Full fuse and higher not so good. Kiln wash the best. I started just stripping and recoating in the kiln.

Zyp still has to be removed. It can be brushed away with a paintbrush and then resprayed. However, it's nasty stuff to breathe and so I would not want to spray or brush in an enclosed area. I always work outside, and often even put on my respirator (or hold my breath - ha ha ).

First of all, Dana. Let me congratulate you on all of the hard work you and Tanya have done for people in the warm glass field.
You both have done a lot to further the education and the fun of the warm glass community.
Next, Thanks for posting the MSDS for zyp coatings. I think that a lot of people are now aware of the dangers and will take appropriate precautions.
I am well aware of the dangers myself. I have been using it for a long time now, and use a hepa vacuum and OSHA approved mask for chemicals.

using kiln wash seems the most sense to me.
I was even given a bottle of liquid equivalent of a zyp type and chose not to use it.

Buy a drywall sanding attachment for collecting the dust while sanding the shelves inside your kiln.
Hardware stores have lots of them to choose from.

Hi Kevin
drywall sanding attachment ?
Could you please explain ?
I really can not do any even moderately heavy lifting anymore

there are lots to choose from out there some for a lot of money.
Using the carbide open mesh variety sand paper stuck on the bottom of one of these units will allow dust free sanding. Well dust free if the vacuum you are using is of high enough quality and doesn't just blow the dust out the exhaust port of the vacuum. Some have extension handles meaning you would not have to bend over inside your kiln.
I've not tried this unit but it does make complete sense and the reviews are not totally bad.

I tried brushable ZYP boron nitride on fiber molds. It releases one time, firing up to fuse temperature the next time results in the coating sticking to the glass as a hazy film. Zyp has to be removed and replenished with a fresh coat which is pretty impossible on fiber.
