Black frit for use in silk screening glass

[SUEC0227]

My company is looking for a black frit in ink form for use in silk screening flat sheets of glass at high temperatures. However, it must be opaque. What we are using now is not opaque enough. Can anyone help me please?

Welcome to The Melting Pot, hope you enjoy your stay....

First off, some more information might get you more help....

Please keep in mind this forum is a community, we're all plenty willing to help other members of our community, but generally aren't so eager to "Do your homework for you"™. We've only recently had yet another run in with someone else who thought they could exploit the knowledge of this community for their own gains while being vague or dismissive of the status quo here.

So... to answer your question, all I (or anyone) could say is "it depends"

There are a few objective facts we'd need to give a real answer, so some questions:

What kind of glass are you printing on?
What kind of glass have you tried so far?
what kind of high temperatures are you bringing the glass to?

keep in mind that glass as a modern material is one of the most diverse substances known to man. There is glass that is molten at sub-zero temperatures, and glass that can withstand several thousands degrees Fahrenheit with no distortion.... not all glass is equal, and the chemicals used to color and modify glass are highly dependent on the base glass composition.

And some questions that delve more into who you are, and why should any of us want to help you?

Who are you, or more importantly who is this "company" that you're soliciting advice on behalf of?
What are you trying to do?


Please, help us help you.

Whatever you do. Make sure to ask doug about HHO free energy and glass solid vs liquid......

AH, here's some "homework" I spent months doing.

Good luck in your search.

maybe 2 passes, 1st pass white, kiln, 2nd pass black. Registration is a must.1st.kiln cannot cause any distortion. Ink=frit plus elmers?

Also.... what kind of glass are you using? COE? Some specifics would go a long way here in determining how to accomplish what you're trying to do :)

[FredLight]

Would you be willing to compensate me if I just told you what company to call?

[BrassMonkey]

cmon guys its an easy question to answer......
sorry about that SUEC0227

Nile is the best black and works with any coe.

We will be using a float glass of many types (coated, etched, chem strengthened). The temperature we use is @970˚. I have been researching this for weeks and finally one of the vendors I called suggested I use this to ask if anyone had a clue. I am desperate - my boss needs an answer and I have been unable to find anything. Help please! My company is Quantum Coating, Inc. and we coat aviation instrument panel glass with nonreflective coatings.

Sounds like you should hire a consultant. That's what major companies do for these sorts of things.

Being a person that has worked for one of these "major companies"... CONSULTANT!?... LMAO! Yeah right. The consultant is the lowest paid person on staff.

[H1JACK3R]

I guess I'm wrong. Not the first time.

[Greymatter Glass]

I almost feel like we're getting trolled....

This is you guys, and no one on your staff can figure this out?


Anyways....

I'm not sure frit is what you want. You probably want some kind of chemical stain or ceramic material. There are several out there but I confess I don't know much about them. I know there are ceramic enamels that adhere to soda lime glass and fire on at fairly low temperatures. They're usually pad printed, as the abrasive nature of glass and ceramics would pretty quickly destroy a screen.

I would suggest calling someone like PPG, Owens-Corning, Corning, Schott, Kimble, Kavalier, or someone like that... you know, the people who make that type of glass.

Maybe if this helped you you might consider getting your boss(es) to fund a grant for this forum to do top level research.

I'm not sticking up for anybody in this thread, but I do know the politics of these types of companies. I would love to show you guys the website of the company that I just left, but it's very counter productive for me to do so. Either way, the owners of these companies are too proud and secretive to hire outside consultants. They usually find a newly graduated top of their class engineer and make their lives miserable for many years and WAAAAAY under pay. It all just sounds too familiar too me, a young engineer on the guillotine extremely scared about their future because the boss or the owner is telling them they're good for nothing because they can't figure out something they were never taught or even told about.

I'm not knowledgable enough about all the aspects of glass to understand how this person could be trolling or what the motive would be, but if I knew the answer to the question I would tell them because it just feels like a situation I have been in before.

I agree, a consultant needs to be paid to get your company this answer.

I worked at a production glass slumping / fusing studio for a while. Our specialty was creating glassware utilizing intricate floral patterns sandwiched inbetween two pieces of sheet glass. This was accomplished by using a series of stencils, overlaying each color, until the end design was created. We used powdered 96 Coe glass.

Here is a secret that I don't mind sharing, since they layed me off on bad terms, we used Aloe Vera gel with just a bit of water, on a sponge. Wipe the glass with the aloe Vera solution and the powdered glass will stick for a few minutes, pretty well. The aloe Vera burns off with no residue.

I remember that black was one color that you had to do two maybe even three coatings to make it opaque, otherwise it would be more of a transparent dark purple.

Not sure that helps, but I'll take that consultant bonus if you're up for it ;)

Not that it would happen, but when people helped me out like that I would make some pretty badass stuff for them in the shop.

Do I read that temperature as 970 F? You can get a cure at 1050 F for Reusche paints if you're willing/able to go higher. They have the oil mediums as well as water miscible mediums. Best Black and Tracing Black are good although I've never screened them, you may have to fire and then do a second process. BTW- frit won't go through any screen I've ever worked with. It's been a long time though.
You may have better answers to your questions on the Warm Glass BB. Some of them paint on glass (including float) for a living and know their stuff.

oops, forgot the link http://www.reuscheco.com/

Sue give me a call. I might be able to help. I have worked with these companies before with the same ideas. Black is Hard but depending on what float glass you are useing there are options for that also. Glass will work just a little complacated. Free consulting is the best.
