What's the name of the stuff?

Post by Vickie »

I've read there is a product that you can use when fusing dichroic pieces that eliminates the "black halo" that usually happens. Does anyone know the name, and where I can get it?
Thanks,

Vickie,

Can you give more information on the black halo?

All I can think of, is that you are referring to the edge of the black glass the dichro is applied to. As the glass fuses, the vertical face becomes a 1/8" or less border around the dichro surface, as the glass melts down to plane. If that is it, there isn't any spray on product that will eliminate this.

There are other ways. Brock

Brock,

That's all I can think "black halo" would be, but you never know.

buy dichro on clear, not black.
if you want black substrate, cut the base from black, and put dichroic on clear on top of the black.

black halo

Post by Vickie »

I think my halo sounds like what Brock described, but I found the article which said to use Fuse Master 975 Black Magic Overglaze. The article says to apply this to the ground edges of the dichro to prevent a "shadow" when the project is fired. Have you heard of, or used this stuff. Maybe the "shadow" is not the same thing as my "halo"
Thanks all,
Vickie

Often the appearance of that flattened vertical face on the edge of a piece of glass, is different than the appearance of the glass itself. I don't know why, I just know it can happen. An overglaze of any type can ameliorate this effect. Brock

Isn't the Black Halo that thing that hovers over Evil Amy?

Brock, did you ever figure out what it means when someone declares 'Oh God, my Cheerios!'?

So many mysteries.

The "shadow" is probably the scummy/devitrified edge that happens if you've used a grinder on your glass before firing. That can show up on any color.
And I think the stuff is actually called Back Magic, because it's meant to be used on the underside of pieces. Since it fires at 975 degrees, you can fire a piece upside down to overglaze the back without reaching a temperature that would melt the glass and affect the front side. I don't know what would happen if you apply this overglaze and fire to a full fuse, or even a regular fire polish temp, but I don't think it's meant to be fired that high.
