The intermediate tone from the three pre-calibrated Eternal gray washes, supplied in a 30 ml bottle and marketed as drawing ink. It is the 'middle' gray of the range — the tonal bridge between Dark and Light — and statistically the most used in the set, because mid-tones cover the largest surface area in monochrome works. The pre-calibrated formula gives you the same neutral gray in every bottle, without the inconsistencies of manual dilution, making it suitable both for those testing the range and for artists who consume large volumes of the mid-tone.
Why does it say 'drawing ink' on an Eternal Gray Wash product?▾
This is the official designation under which the product is marketed: drawing ink, not for tattoos. Any use other than the stated purpose is strictly the consumer's responsibility — the shop assumes no liability for use in any other purpose. If you buy it, buy it with this purpose in mind.
How do I choose between Dark, Medium and Light from the Eternal Gray Wash series?▾
Medium is exactly the middle of the spectrum: on a scale from 0 (white) to 10 (solid black), it sits at approximately 4-5, while Dark is at 7-8 and Light at 2-3. It's dark enough to be clearly visible, but light enough to allow layering with Dark without harsh demarcation lines. If you buy a single bottle from the series to test the range, Medium is the recommended choice — then add Dark and Light if you need the full tonal range.
Can I work with just Medium, without the rest of the set?▾
Yes, for many styles it's sufficient. You can create lighter or darker tones by varying pressure and number of passes, and many neo-traditional artists work with a single gray tone. For realism and portraits, however, the three tones together offer full depth: Medium forms the tonal base, Dark builds deep shadows, and Light provides highlights.
How long does a 30 ml bottle last and why does Medium run out first?▾
According to the manufacturer's description, a 30 ml bottle covers approximately 15-25 sessions with typical shading use, depending on the surfaces worked. Medium runs out the fastest in the set because mid-tones cover about 60-70% of the surface area of a typical monochrome work, while deep shadows and highlights together occupy only 30-40%. That's why many artists buy this tone separately or in double quantity.
How do I store and handle the ink hygienically?▾
Shake the bottle for about 30 seconds before use, pour only what you need into disposable cups and never return the surplus to the bottle — any leftover ink in the cup is discarded. Wipe the bottle neck and put the cap on immediately after pouring, to avoid contaminating the thread. Store at room temperature, away from sunlight, and do not use the product if the seal is compromised or consistency seems altered.
Is the ink vegan? Does it change color over time?▾
Yes — the formulation is 100% vegan, compliant with EU REACH regulations and gamma sterilized, with traceable batch on each bottle. The purified Carbon Black pigments remain in stable suspension, and the tone is calibrated to stay a neutral gray, without chromatic shifts towards blue or brown — one of the reasons the Eternal series is appreciated for monochrome work.
