FOTOSPEED FS LE30 liquid emulsion 250ml (035-7120)

Fotospeed LE30 Liquid Emulsion is a Black & White photographic emulsion grade 2 supplied in a form that
allows the user to apply it to any surface if the following instructions are adhered to. At all times it should be
remembered that you are dealing with a light sensitive product and therefore the precautions for a normal B&W paper should be followed.

PREPARATION FOR USE

Heat container in a water bath to a maximum temperature of 50°C. Leave the lid on to prevent water entering the tub or bottle. The emulsion should turn to a creamy liquid in approximately 5 minutes.

Pour emulsion required into a beaker and add water at approx 40°C to the emulsion at the mixture of 1 part emulsion to 1 part water. Gently agitate the beaker to cause the water and emulsion to mix. Continue heating the beaker until a uniform mixture is obtained. At this point the emulsion is ready for application. For richer images the emulsion can be used neat.

APPLYING THE EMULSION

You may work under RED safelight but keep the safelight at least 3 feet away from where you are coating.

Ensure that the surface to which the emulsion is being applied is clean and free from grease.

For surfaces such as glass, ceramics, stone etc. a subbing layer is recommended to assist the emulsion to adhere to the surface. This is achieved  by using any crystal clear varnish. Paint the varnish onto the surface and allow to fully dry, this now forms a key to which the emulsion can attached itself.

Pour the emulsion onto the surface to be coated and either brush it across the surface or if the surface is perfectly flat a rubber or plastic roller can be used. Remember that ideally the temperature of the emulsion should be maintained otherwise as the emulsion cools on contact with a cold surface then you
will end up with a thicker emulsion layer.

Once coated either place the coated surface in a refrigerator (ensure that the fridge light has been disconnected before opening the fridge!) for about 5 minutes to allow the emulsion to harden. Alternatively a hairdryer set to cool can also successfully dry the emulsion.
