Formula 23 Original stands out for its pure black intensity that maintains after healing without shifting toward blue or grey. Mario Barth's proprietary formulation combines high-purity carbon pigments with a dispersion medium that ensures superior coverage and perfect needle flow. It has been the industry reference standard for over two decades.

Yes, this is one of its most valued qualities. Formula 23 Original's consistency is dense enough for clear, precise lines but fluid enough for uniform shading and dense color packing. Many black inks excel at either lining or shading, but Formula 23 performs excellently in both techniques.

No, one of Formula 23 Original's defining qualities is its long-term chromatic stability. The carbon pigments used in the formula are chemically stable and do not undergo degradation that could cause color shifts. The black remains black in the skin, softening naturally and uniformly over time without developing blue or green undertones.

Absolutely, Formula 23 Original is excellent for traditional American (old school) style due to its ability to produce bold, thick, uniform lines and dense solid black areas. Its superior opacity makes it ideal for strong outlines and black fill areas that are the signature of traditional style.

While possible, it is not recommended. Mario Barth created the complete pre-mixed greywash range (Light, Medium, Dark) specifically to eliminate manual dilution inconsistencies. If you must dilute, use Intenze Mixing Solution or Distilled Mixer instead of water to maintain formula stability and avoid pigment separation.

Consumption varies considerably depending on style and size. A medium-sized forearm tattoo may consume 5-20ml of black ink, depending on the amount of fill and shading. A complete back piece may require 50-100ml or more. The 300ml format provides enough for an active artist over several months.

Yes, Formula 23 Original is produced under sterile conditions at Intenze's USA facility. Each batch undergoes rigorous sterility testing before distribution. Bottles are individually sealed to prevent contamination. The ink is ready to use straight from the bottle without requiring additional processing.

The number 23 refers to the proprietary formulation developed by Mario Barth. After multiple iterations and tests, formulation number 23 was the one that met all of Barth's performance criteria: maximum intensity, perfect consistency, clean healing, and longevity in the skin. Since then, the number 23 has become synonymous with quality in the tattoo industry.

Yes, Formula 23 Original is fully compatible with modern pen machines such as Cheyenne, FK Irons Spektra, Bishop, and others. Its optimized consistency allows uniform flow through pen-specific cartridges, delivering the same excellent performance as on traditional coil or classic rotary machines.

Both are premium black inks from Intenze but with different characteristics. Formula 23 Original has a more versatile consistency, suitable for both lining and shading. Zuper Black is formulated to maximize density and opacity, preferred for extra-bold lines and absolute black areas. Many artists use both, choosing based on specific requirements.
