Most alt photo processes involve wet chemistry, such as making solutions from distilled water and dry chemicals or diluting concentrated solutions.
Wearing nitrile gloves, dust mask, safety glasses, a plastic apron, and closed toed shoes are recommended to make solutions and process prints. Read the SDS (safety data sheet) on the chemicals you will be using. Have good ventilation for volatile agents (fume hood, outside, or wearing organic vapor respirator).
In this website I try to avoid very toxic agents such as lead, mercury, cadmium,and uranium.
Dichromate is used in many processes in this field and I try to avoid it where possible.
Some processes are very simple, and some are more complicated. If you lack basic chemistry skills, try the simpler processes.
A battery operated gram scale, Pyrex measuring cups, canning jars, Pyrex baking dishes or plastic photo trays are useful.
Try a process at your own risk. Do not use any dish used for alt photo for cooking or drinking. Don’t store any chemicals in the kitchen refrigerator or pantry. Keep all chemicals locked away from children or nosy adults for that matter. Don’t smoke or eat around chemicals. You need water for spills, eye wash, etc. Think about what can happen: What if I spill this bottle of acid? What if I sneeze into that fine green powder? Always add acid slowly to water while stirring to dilute it; the opposite way may blow concentrated acid in your face. Same applies to caustics.
