NT Glass Colors

by Saulius (SJ) Jankauskas

The NT color line is our most popular line of kiln fired glass color for many reasons. They come in powder form and are liquified by adding our Glass Medium. They are all non-toxic and food-safe, even the metallic colors and this is important to us and to our environment. The NTs fire to rich, glossy, vibrant color, semi-opaque to opaque and can be used dry for stenciling or sifting techniques. They can be mixed with each other to form an unlimited range of colors including tints and shades of color. The NTs are perfect for artistic creations, commercial applications, in conjunction with stained glass techniques, used in schools and all types of studios. NT colors can be used on most types of glass, float glass, ceramic bisque and over glazed ceramic pieces. Colors can be used on the same piece along with our Original color line but you cannot mix the two colors lines together. For more detailed information on our products and what they can do please click on Basic Glass Information.

From Left to Right: NT Colors; Glass Medium; Metallics; and Outline Black and Outline White with a Decorator Bottle

Glass Medium is also non-toxic and is added to the powdered color to hold the color to the glass surface before firing and will ensure a smooth, glossy surface. Place it on the glass prior to stenciling or sifting techniques to hold the color in place.

The NT color line also contains four metallic colors: White Diamonds, Gold Dust, Copper Glow, and Silver Sheen.

Outline Black and Outline White come in liquid form and dry hard to allow colors to be brought right up to the line. Place color in Decorator Bottle for outlining or use a brush. Photo shows our logo created using Outline Black in the Decorator Bottle and then many different NT colors blended to form interesting patterns in the glass piece.

Application

For powdered colors mix with our Glass Medium, 1:1 to start. You are looking for the consistency of melted ice cream or heavy cream, and then add a drop or two of water as this makes the color flow a bit better. The color should self-level on your surface. If it does not you need more Glass Medium or water. If it is applied too thinly it will be streaky (which can be a technique also!). To check your application, view it from the underside of the glass and it should appear opaque. Colors can be thinned and then brushed, sponged, sprayed or applied with a pen. Mixed color can be stored indefinitely but will need to be stirred well as it tends to settle in the jar and my need a drop or two of Glass Medium or water. We have empty 1 ounce jars available under Specialty Items.

Firing

Average firing range is 1425F to 1550F in a glass or ceramic kiln. Colors will hold their vibrancy to a much higher temperature when used on ceramic, porcelain, terra cotta, etc.
