If you’ve done any silicone mold making, you know to treat the material like liquid gold. Silicone ain’t cheap. That’s a fact of life. If you end up mixing too much of the goop for your current mold making project, you could be scrambling for some way to use it that doesn’t waste the dollars you’ve just poured into a cup.

A useful little article, that.
To the fellow propmakers of Propnomicon's following ...
There are three other things I have used the extra silicone for:
mixed with an excess of fine abrasive and pushed into a flat, rectangular mould, you get one of those neat abrasive erasers that are so useful for polishing out the highs of other castings (especially bronze) to get a well-handled look.
The other thing is to cast rubbery components (like the allen-bolts in Bill Doran's article) - for use as buffers and spacers - or even as supports for use in a later, complex mould.
The final use is to seal sand or lead-shot loading that fills a hollow casting in order to give the artefact some extra heft.
