If you use the Silverprint SE1 (or any other liquid emulsion), get a plastic knife and use it to "mash up" the emulsion in the original bottle. Shake some of the lumps out in to a beaker and melt these in a water bath. Once melted, add an equal volume of distilled water and then coat your substrate. Doing it this way saves having to constantly remelt a full bottle and incur heat related fogging.
