Eclipse is our most popular, easy to use black.  When pulled down thin, it maintains a smoky black color, versus purple, green or blue like other blacks on the market. Described by many as “bullet proof”, Eclipse does not contain any chrome, so graying and checking are not a major concern. If you need a more saturated black, check out Raven.

Working Tip: This color can handle different flame atmospheres but as always, we recommend working in a neutral flame.

Product Specifications:
Each rod is approximately 20" in length and 7mm in diameter.

Artist Description by Mike Shelbo:
"Eclipse is a dense, transparent black that can withstand long working hours and many flame atmospheres. It work smooth and melts into itself without a trace of layering.

It is a bit stiffer than clear when blowing it out or drawing it down. Eclipse stringers are black down to 1mm when they appear to be a dense smoky transparent black. A 2mm or 3mm thick layer of Eclipse over any tubing is enough to create the appearance of a solid black colored tube; keeping the clear underneath helps core heat remain while you work and saves on color versus coiled solid color. Reheating as many times as you want and numerous or long hours of kiln cycles don't seem to be an issue with Eclipse. I used it inside and on the back of large marbles with great results.

Basically it’s my new go to black. I use GA Raven all the time and now Eclipse will fill tons of those jobs where really long flame exposure time or atmosphere was previously an issue with how my black looked in the finish of the piece. Eclipse stays really black with a super gloss finish that makes it the best and most workable black I have tried in the color palette for today's lampworker.”

Black is Back

This particular black has been an amazing change to my work. I've tried a lot that just smoke out and give you a rough surface on your work, but not this! Super smooth and works the absolute easiest! It stays a nice dark color even when pulled into the thinnest stringer. I know everyone has their preference but this color is a consistent winner in my book.

very versatile black

This deep saturated black is lighter than jet black or raven, but darker than onyx making it great for thing encasement work and stringers. Works like grape, seems to have a somewhat purple/blue saturation. A good addition to anyones palette

Eclipse by Glass Alchemy has your back! bomb proof! streak proof! abuse it! talk dirty to it! it will maintain black! i challenge anyone out there to prove otherwise. surface happy, encased happy, implodes happy! do yourself a favor and dont waste your time with any other black.

Blacker than Black

Well this color rocks! I was so tired of playing with other blacks till this one came along. Its a bit on the stiffer side but works nice and well once heated. I did somehow get some grey streaking the first time I played with it (unworked on the rod), but then it went away once the color was worked. Since then I've seen nothing but a nice true black.
