Test Results :: Black Pearl

1 - Plain, 2 - Plain (reduced), 3 - Plain (reduced & encased), 4 &5 - w/ Tuxedo, Copper Green, Opal Yellow, Ivory, and Peace

Precision 104 glass and I have not had a very extensive relationship, but I have deep love for this colour. Precision Black Pearl is a really beautiful reducing silver glass colour that reduces to a cloudy and variegated range of blues and greens and even a shiny oilslick that exudes a rainbow of other colours.

To reduce Black Pearl:
Once you've shaped your bead that includes one or more Black Pearl elements, you should let it cool ever so slightly and then turn down your oxygen until you have an orange/yellow candle in your flame but there is still some blue surrounding the candle, and give the bead a little bath in the reduction flame near the top of that orange candle.

As with all reduction colours, it is better to do a few quick passes and check your progress after each one than it is to potentially overdo it. Black Pearl goes blue first, and then progresses through to green and gets cloudier after each pass in the flame. It is not a fast process, so you don't have to be too worried about accidentally overdoing it, but go slow until you get the hang of it.

Black Pearl keeps its reduction under clear, but it does not really develop a mother of pearl look to it.

I did not reduce these beads because I thought that would make it easier to really see the reactions.

Copper Green goes a dark, greyish pink on top of Black Pearl, with a bright yellowish outline. On top of Copper Green, Black Pearl develops a bit of a ragged appearance that  has a faintly pink outline. The Copper Green also takes on a shiny pinkishness all over in this combination.

Opal Yellow on top of Black Pearl develops a dark border which is ringed by a bright silver line. The same reaction appears when the Black Pearl is used on top of the Opal Yellow except that it is inside out -- the silver line is on the inside of the stringer rather than the outside.

Ivory and Black Pearl have the same reaction as Opal Yellow and Black Pearl except that the reaction is stronger and sharper. Like with Opal Yellow, when Black Pearl is used on top of Ivory, you get the same reaction except that it is inside out.

On top of Black Pearl, Peace turns yellow. When Black Pearl is used on top of Peace, you can see a little yellow develop on the surface of the Peace.

Here are some fun beads that include Black Pearl:

I used Black Pearl in the background of this mushroom bead, underneath all of the surface decoration, so you can just sort of see it peeking out here and there.


These goddess beads are both made from solid Black Pearl. You can see here the cloudy blue reduction and some surface oilslick effect.


And finally, these sets are made from Black Pearl and Opal Yellow. I love these two colours together a lot.


  1. Still have a lot of Black Pearl Rods at home ... :0) Have to try it over Opal Yellow - that looks great!
    Thanks for sharing!

  2. Black Pearl and Opal Yellow is definitely a yummy combination :) Thanks for reading, and for your feedback!
