Patreon for electroplating creators — 2026 edition

Faraday's law deposition calculations, copper and nickel bath chemistry, electroforming on wax mandrels, anodizing Type II oxide thickness, and the Apple Tax.

Electroplating Patreons retain when they deliver the electrochemistry and process engineering layer that before/after transformation videos compress away — Faraday's law deposition rate math, bath concentration maintenance, current density effects on deposit morphology, and the mandrel preparation sequence that separates a clean electroformed shell from a pitted adhesion failure.

Who creates electroplating content on Patreon

Hobbyist copper and nickel platers document their bath chemistry for studio setups: acid copper sulfate bath (CuSO₄·5H₂O 180–240 g/L, H₂SO₄ 45–90 g/L, HCl 40–80 ppm for brightener activity, temperature 18–24°C, current density 2–4 A/dm²); Watts nickel bath (NiSO₄·6H₂O 250–300 g/L, NiCl₂·6H₂O 45–60 g/L, H₃BO₃ 35–45 g/L as pH buffer, temperature 50–60°C, pH 3.8–4.2, current density 2–5 A/dm²). Their Patreon deliverable: monthly bath maintenance log with titration results and additions made to restore composition.

Electroforming artists create sculptural shell objects by growing a metal shell (typically copper, sometimes silver or gold) onto a non-metallic mandrel. Mandrel options: wax sculpture (lost wax — wax melted out after electroforming); 3D-printed resin or PLA (can remain inside for rigid sculptures or removed by solvent — acetone for ABS/ASA, DCM for resin); natural organic (leaves, insects, coral — create delicate hollow replicas after burnout or decay). Surface preparation: wax mandrels brushed with conductive silver paint (Electro-Dag or colloidal silver in IPA, 5–7 μm dry film thickness); resin prints require silver paint or vacuum metallization; natural materials painted with graphite or silver paint. Deposition rate governed by Faraday's law: m = (M × I × t) / (n × F) — mass deposited = atomic weight × current (A) × time (s) / (electrons per ion × Faraday's constant 96,485 C/mol). For copper (M=63.5, n=2): at 1A for 3600s, m = (63.5 × 1 × 3600) / (2 × 96,485) = 1.18 g copper deposited. Deposit thickness: t_µm = (m / (ρ × A)) × 10⁶ — density of copper 8.96 g/cm³, area in cm².

Anodizing educators cover aluminum Type II sulfuric acid anodizing: 15–20% H₂SO₄ by weight, temperature 18–22°C (critical — above 25°C produces soft porous oxide prone to dissolution, below 15°C produces dense but thin oxide), current density 12–18 mA/cm², time 30–60 minutes. Oxide layer thickness: by Faraday's law variant, approximately 0.5–0.6 µm per amp-minute per dm² for Type II. Standard decorative anodizing target: 5–25 µm oxide thickness. After anodizing, the oxide pore structure accepts acid dye or reactive dye in solution — dye concentrations 1–10 g/L, temperature 50–60°C, immersion 10–20 minutes — then sealed in boiling deionized water or nickel acetate solution (5 g/L Ni(CH₃COO)₂ at 80°C) to close pores and lock dye, improving UV and wear resistance.

Tier structure that retains patrons

Electroplating Patreon tiers convert when they solve the chemistry maintenance problem — most hobbyist platers produce excellent results initially but lose bath performance over weeks as concentration drifts, contaminants accumulate, and pH shifts. A creator who teaches titration methods and correction additions is providing ongoing value every patron uses.

• Bath Chemistry ($5–8/mo): plating bath formula archive for copper, nickel, silver, gold strike, and black oxide; monthly bath maintenance titration log with corrections made; pH and temperature target tables by plating type.
• Anode ($15–20/mo): everything above plus monthly electroforming process documentation with mandrel prep sequence, conductive paint application technique, deposition rate Faraday calculations, and mandrel removal method by type; wax sculpt STL files for mandrel resin-printing.
• Rectifier ($30–40/mo): full access plus anodizing process guides with oxide thickness calculations, dye chemistry for 5–8 standard colors with concentration and time tables, sealing comparison (boiling DI water vs nickel acetate vs mid-temp seal), and one-on-one troubleshooting for patrons experiencing pitting, burning, or adhesion failures.

Faraday's law applied to deposit planning

Every plating thickness decision starts with Faraday's law: the mass of metal deposited is proportional to the charge passed (current × time). For gold flash plating (m = 196.97 g/mol, n = 1 electron for Au⁺ gold potassium cyanide bath): at 0.5 A/dm² on a 2 dm² piece for 3 minutes — charge = 0.5 × 2 × 180 = 180 C; mass = (196.97 × 180) / (1 × 96,485) = 0.367 g gold; thickness on 2 dm² = 200 cm² area = 0.367 / (19.3 g/cm³ × 200 cm²) × 10⁴ µm/cm = 0.095 µm — a flash coat just sufficient for color coverage without meaningful wear protection.

Current density directly controls deposit morphology: too low (below minimum recommended CD) produces dull, rough, or dark deposits due to incomplete bath additive incorporation; too high (above maximum) produces burned edges (current concentration at high-geometry points causes hot deposition with rougher microcrystalline structure) and hydrogen gas bubbles trapped in the deposit producing pits. The Hullcell (a standardized 267 mL trapezoidal test cell with a cathode spanning a 7:1 current density range at a single impressed voltage) allows evaluation of plating bath chemistry across the full CD operating window in one 5-minute test.
