If a student’s print washes away completely in the water bath, what is the most likely cause? *

10 points

The paper was exposed for too long.

The paper was wet or damp during exposure.

The water bath was too cold.

The student used too much hydrogen peroxide.

You should use a high-pH alkaline detergent or soapy water to wash your cyanotype prints for a deeper blue. *

10 points

True

False

During exposure, the paper changes from yellow-green to a dark, metallic olive-gray. What is this phase called? *

10 points

The Oxidation Phase

The Solarization/Bronzing Phase

The Bleaching Phase

The Saturation Phase

What is the purpose of adding a splash of Hydrogen Peroxide to the final wash water? *

10 points

To wash away unreacted chemicals.

To bleach out mistakes.

To act as a catalyst for instant oxidation (deepening the blue).

To make the paper more absorbent.

If a print has blue 'speckles' or spots in the white areas, what is the most likely culprit? *

10 points
