Re: bell kiln repair

For fiber, top only should work.

For brick, both.

Most likely the color will change or fade, but it's worth a try.

.2mm should be thin enough. Try a small piece as a test.

Re: copper inclusion

2mm is too thick. It will almost certainly crack.

No formula that I'm aware of. It would depend on the particular metal, of course.

Michael Stevens wrote:how could make the painting medium?


You can use anything that will mix with the oxides and that burns off cleanly in the kiln. Many glues will work or if you can get some ethyl methyl cellulose or carboxy methyl cellulose (CMC) you can make your own glue that will work well.

Re: Dichoric & iridized

has anyone tried to spray their own tin chloride? I have no access to iridized glass, I think it would be cool to add it to some of my scraps and make iridized frit bslla Yes, I've done this. It's fairly hazardous: https://beta-static.fishersci.com/content/dam/fishersci/en_US/documents/programs/edu...

Re: Are Armstrong Glass' COE 82 and Optul COE 82 the same product?

I'm pretty sure they're the same, made by OPTUL Spezialglas GmbH in Germany. As I recall, Armstrong imports their FloatFire from Germany. http://optul.de/en-arc-82.php The only place I know that carries it in the US is Armstrong, but you could contact OPTUL via their website and ask if they have ano...

Re: Using oxides as colorants

Can I mix with medium and paint with them? Can I sift them onto the glass like frit powder? What temperature does it need to set? Either method will work. Full fuse or close to that. Colors may change with different thicknesses. If sandwiched between glass, there will be some bubbling, which can be...

Re: Silver foil & leaf

I've used tarnished silver foil once before and it worked fine. Don't know if this is applicable to your situation, I was doing a reaction where the silver would change color anyway.

Given the thinness of the silver, I don't think there's any easy way to remove the tarnish.

Re: kiln shelf

The big issue with kiln shelves is the cost of shipping them, so it's best to find someone close to you who sells them so you can pick the shelf up rather than have it shipped.

Where are you located?

Re: zyp coating

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 ...
