The electrolyte is the solution that allows electricity to flow from one plate to the other. There is a different electrolyte for different metals. For copper, the electrolyte is copper sulfate. For zinc, the electrolyte is zinc sulfate. For steel, the electrolyte is ferrous sulfate. All three chemicals are readily available online; copper sulfate is … Continue reading The Electrolytic Solution

Virtue No. 463 – Adjustable Strength

Besides time, you can affect an etch through the strength of the current flowing through the circuit. The lower the amperage, the more delicate the etch, and the finer the details. Conversely, the higher the amperage, the stronger the etch, the courser the details. Amperage, voltage and ohms are often described using an analogy to … Continue reading Virtue No. 463 – Adjustable Strength
