We show how to make conductive silver ink.

1g of silver acetate is completely dissolved in 2.5mL of ammonium hydroxide (30%). 0.2mL of formic acid is added dropwise with stirring. Solution is then capped and allowed to stand for 12 hours. The solution is decanted and then pushed through a 0.2 micrometer pore syringe filter.

Draw it onto a surface and let it dry. Then heat it to 90 celsius to sinter it into solid silver.
