Dense White (0313) Reaction Potential

Postby lbailey128 » Sun Apr 21, 2019 2:23 pm

Have worked a fair amount using Dense White with French Vanilla and now testing other colors listed to react with Dense White. Oddly enough there appears to be no reaction with Tomato Red, Red Opal, Spring Green or Marigold Yellow.

According to BE's "Reactive Potential" chart all 4 of these colors contain Sulfur/Selenium and Dense White contains Lead. I understand the definition of "potential" but 4 out of 4 tests fail to produce a reaction? (Test tiles fired to 1480F with 10 min hold, Dense White base, other colors on top).

Obiviously I'm missing something.

Also, can anyone share what other colors do produce a reaction with Dense White?

Thanks

Anybody from BE care to comment? Surely someone has seen the question?

Thanks

Hi,

Sorry for the delay in replying to your question!

When combining two potentially reactive colors that are opalescent (so we can't see through them, we can only see the surface) and also have very high contrast with each other, the visible reaction may be minimal. Also reactive colors are usually medium to dark in value, and may have a very similar value to one of the colors, so there is not enough contrast to see it well. Does that make sense?

I might be able to find some test tiles with those combinations, and show you the results we got.

Do you have photos of the reactions (or lack of reactions) that you experienced? If you can process those into images that are about 500 pixels wide, those should be easy to upload to the Forum. Then we can compare notes!

Hi,
Bonnie dropped by today with some samples. We, too, are not getting any reaction from 000313 and cadmium-seleniums, and sulfur ambers, except for French Vanilla Opal (000137). Here are some shots of our samples:

Because Dense White has lead in it, it is included on the Potential Reaction chart, even if it doesn't alway react. It might require a different fusing cycle to coax it to react.

Thanks Mary Kay. Guess I got the testing right.

Thanks Leslie, just got in a couple of sheets of Robin's Egg. Testing now....
