You don’t need super high-tech tools for the artisanal fabrication of photosensitive emulsion. Nevertheless, it’s best to follow a few basic recommendations concerning the materials or fluids that are used, in order to avoid adding variables of uncertainty!
In order of preference préférence :
When fabricating emulsion there long stretches of cooling, drying, or agitation which do not require one’s actual presence in the laboratory. In order to be able to leave the darkroom without risking fogging the emulsion, we can install an opaque entry vestibule. Two dark curtains separated by about a foot or two tight doors should do the trick.
Some of the obligatory stages of a protocol don’t allow, or very marginally, for any direct experimentation.
For gelification, we can pour the emulsion into s8 box covers in order to obtain a thickness of 3mm (two boxes of 90m are fit for 170ml of emulsion).
It’s important to rinse all utensils (recipients, stirrers, etc.) with distilled water, to avoid any unforeseen contamination.
Is needed for several phases: nucleation, chemical and physical maturation, as well as the ainsi que le couchage de l'émulsion sur le support film.
