Dark edge around white frit

[Tonyb]

Hi,

I'm a newbie and have made 3 beads using red as a basecolour and white frit. What happens is that I get a dark grey outline to the white frit.

Is this just the chemical reaction between these 2 colours or do I have the flame wrong?




Thanks
Tony

It's a reaction - use it to your advantage 

[Shirley]

Rather nice reaction, if you ask me

[Margram]

If you do want to avoid it, try encasing the base bead in clear before adding frit

I like that effect, although appreciate that it was not what you planned.

I rather like that too

Thanks everyone.

Are there colours that cause this more than others - do all reds do this, or will it only be this particular red and others might not give this effect?.

Thanks Tony

There are lots of colours that react, Tony

I don't know the equivalent colours in lamp-working glasses, but in terms of Bullseye glass, you can expect reactions between copper bearing glass (turquoise, greens, etc) or lead bearing glass (a strange mix of colours here, but includes white) and Sulfur bearing glasses (reds, yellows, creams) - and then you can also get reactive clear glass (in Bullseye anyway) although they don't say why that reacts (magic, I guess).  And then add silver leaf/foil into the mix too...

Bullseye Reaction Chart

Remember the above is for Bullseye fusing and rods. I am sure there's a Coe 104 one around too,


Not ALL colours will necessarily react - there are plenty of stable blues and whites, although it looks as though the majority of red range are reactive (again, I am only referring to Bullseye).

Meant to say, great reaction.

I think its beautiful ! I love reactive colours though they make interesting patterns !

That's interesting, what glass did you use? in effetre glass, you can get great reactions with copper green, but the lines are much thinner than in your reaction.

Why not try a bit of experimenting to see what happens with different glasses? Which frit is it, by the way?

That's interesting, what glass did you use? in effetre glass, you can get great reactions with copper green, but the lines are much thinner than in your reaction.

It if effetre - 591432 Opaque Medium Red with Enamel White frit.

I think the white particles in the frit are not white but ivory. Ivory reacts with several colors like the special colors, copper holding colors etc.

I have this frit, and also the Kugler Dense White for this very reaction - they are the nearest thing to Zimmerman Z74 frit which was one of the ingredients in Val Cox Silver Lake.

The frit goes a beautiful feathery blue over silver leaf and is great in organic beads.

Don't think it's ivory though.
