Dark Ruby - Northstar
Dark Ruby is the most saturated of the transparent striking rubies Northstar produces. It must be worked in a hot oxidizing flame to prevent liveriness. Because it is so intense it can be easily flame struck. It is most useful for small sculptural accents, cane work, and stringers. When fully struck, it can yield a rich opaque Chinese red.
Second quality glass can have the properties of odd quality glass, but may also have small stones, air bubbles, vary in tone/shade, or the shape can be very out of round. Both odd and second quality glass can provide a great value to the right person.
Ratings & Reviews
Dark Ruby is extremely forgiving
I use Northstar’s Dark Ruby all the time for production work because it’s extremely tolerant of any flame chemistry I hit it with. It always comes through. <br><br>And on a side note, if you run it in a striking cycle in your kiln, unlike many other colors, it will not go well. It gets foggy and irregular.
