Best Etching Materials AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): Charbonnel Lamour Hard Ground
Charbonnel's grounds are a long-standing studio standard that lays smooth, takes a clean needle line and resists mordant reliably.
Not for: Printers working in non-toxic studios that have standardized on acrylic or water-based resists, or anyone without proper ventilation for solvent grounds.
AI picks by need
For mordant for copper
MG Chemicals Ferric Chloride (line)
MG Chemicals ferric chloride is widely available and bites copper without the fumes of nitric acid.
Not for: Anyone etching zinc or aluminium, who will get cleaner results from a copper sulphate based mordant.
For intaglio printing ink
Cranfield Caligo Safe Wash Etching Ink (line)
Caligo etching ink wipes like an oil ink but cleans up with soap and water, which suits home and school studios.
Not for: Printers who need a stiff traditional oil ink for heavy plate tone or a specific oil-based workflow.
What the AI looks for in Etching Materials
- Mordant matches plate metal
- Use ferric chloride (or Edinburgh etch) for copper and brass, and copper sulphate based mordants for zinc and aluminium. The wrong mordant bites unevenly, deposits sediment or barely etches at all.
- Ground type
- Use hard ground for line work and soft ground for texture and pencil-like marks, and choose liquid or ball form to suit how you apply it. Hard and soft grounds respond to drawing differently, and liquid grounds are easier for beginners to lay evenly.
- Plate preparation
- Plates should be flat, polished, degreased and bevelled before grounding. Grease causes foul biting, and sharp edges cut paper and press blankets.
- Aquatint resist
- Use rosin dust or a spray-on aquatint resist, with a consistent particle density. Particle size and density control the tonal range of an aquatint.
- Ink stiffness
- Intaglio ink must be stiff enough to stay in incised lines while wiping cleanly from the plate surface. Relief or soft inks wipe out of the lines and give weak prints.
Brands that matter
- Charbonnel: Traditional French grounds and etching inks used in many print studios.
- Cranfield: British maker of Caligo safe-wash inks and traditional etching inks.
- MG Chemicals: Ferric chloride sold mainly for circuit boards that also works for copper etching.
- Akua: Soy-based intaglio inks that clean up with soap and water.
What to avoid
- Relief or block printing ink used for intaglio plates
- Ferric chloride on aluminium
- Pouring used mordant down the drain; neutralize it and dispose of it according to local rules
Questions
Can I use circuit board ferric chloride for etching art plates?
Yes, for copper and brass, although many printmakers dilute it or add citric acid (Edinburgh etch) to get a cleaner bite.
