The Taming of EDP- A Lampworker's Secret

How many of you love edp (evil divitrifying purple)? Show of hands... How many of you hate it? Wait! Those are the same people. Well, I used to feel the same way... The color is beautiful, but it tends to just sit on the sidelines and watch me pass it by over and over again- the wall-flower of my studio.

The other day I was feeling adventurous and pulled a rod out  - oh, what the heck- why not. I made a portal bead base, rolled it in a bit of white enamel, and started adding some edp and other colors. And guess what? No devit- a practical miracle. OK, I'm thinking, maybe I just didn't notice it- maybe it will come out of the kiln looking ug-ly. But I'm just gonna try that again and see. So I did. And guess what- no devit again.

OK, I'm thinking, I must just be holding my mouth right today. We'll see what happens when I do this tomorrow.

And my un-scientific assessment of the situation is this. If you roll a bead in white enamel and apply the edp, you get rid of both the 'e' and the 'd' and end up with just the lovely purple you always wanted. There is a bit of edp in all of the beads pictured. I was having some other troubles with the tube, and managed to reduce some of the purple in that bead. The edp ended up a bit washed out looking in that bead as well, so there may be other odd things going on that I haven't quite figured out yet. I hope y'all will give this a try and let me know how it works for you.

YOu can get rid of the devit by turning the propane way up (reducing the bead) too you may scum some of the other colours but 10 seconds in acid gets the other colours back where you want them, except copper based colours once they go red I think they stay red!

Ink blue gets yucky brown streaks if you put it in a kiln with double helix silver glasses.....

Interesting to know about the double helix and ink blue.
I've gotten the devit to go away by superheating- but then the bead is usually way out of shape.
