Some context:
Blake famously referred to his relief etching method as the "infernal method," a process of "printing by metals, which is the method the Devils use." He explicitly framed this technical breakthrough not merely as a craft, but as a form of spiritual alchemy that dissolved material illusions to reveal the divine reality within.
His physical printmaking process mirrors alchemical transmutation through several core stages:
1. The Acid Bath as Spiritual Dissolution (Solutio)
In traditional alchemy, the phase of solutio involves dissolving a solid substance in acid to strip away its impure, outer form. Blake mirrored this by painting his text and illustrations onto a copper plate using an acid-resistant liquid (a stop-out varnish of pitch and oil). He then submerged the plate in corrosive nitric acid. [1, 2, 3]
The acid acted as a purifying agent, eating away the unprotected, negative space of the copper. In The Marriage of Heaven and Hell, Blake directly equated this to spiritual cleansing, writing that his infernal method operates by "melting apparent surfaces away, and displaying the infinite which was hid." [1, 2]
2. Reversal and the Union of Contraries (Coniunctio)
Alchemical transformation relies heavily on the coniunctio—the union of opposing forces (like Sol and Luna, or sulfur and mercury). Blake’s technique relied entirely on a physical inversion:
* The Counter-Intuitive Cut: Traditional intaglio etching required cutting into the metal to hold ink in the grooves. Blake inverted this, protecting his lines so that the acid burned away everything except his design. [1, 2, 4]
* Mirror Writing: To ensure the final print read correctly, Blake had to write and paint in reverse directly onto the metal. This required a profound psychological shift, merging the act of writing poetry and drawing imagery into a singular, unified physical gesture. [1, 5, 6]
3. Illumination as the Philosophers' Stone (Rubedo)
The final stage of the alchemical magnum opus is rubedo (redness), where the base matter is successfully transmuted into gold or a perfected state. For Blake, this occurred during the printing and colouring phase.
After using a leather dabber to build up layers of ink on the raised copper surfaces, he pulled the prints through his rolling press. He and his wife, Catherine, then hand-coloured the monochrome prints using watercolors, tempera, and occasionally liquid gold or silver leaf. This final touch literally illuminated the page, turning industrial, mechanical base metals into vibrant, uncorrupted visual art. [1, 2, 4, 7]
By controlling every stage of production in his own workshop—from grinding raw pigments to pressing the paper—Blake bypassed commercial publishers and censors. The printing press was transformed from a tool of mechanical reproduction into an alchemical crucible for the human soul. [4, 7]
