Corrosion intercept is a copper loaded polyethylene film used to scavenge nitrides, sulphides and chlorides. The technology has also been developed into a wide range of products including copper loaded foams and canvas.

Copper is a highly reactive metal and will react with contaminating gaseous ions preferentially. The copper in the plastic behaves similarly to a sacrificial anode.
There are two ways of thinking about intercept for storage

Put your sensitive items in intercept to protect from contamination i.e. lead-point

Put contaminating items inside intercept to improve overall storeroom air quality and trap contaminants inside the intercept i.e. rubber items.
Removing tarnish passively, by just making good storage and display decisions seems too good to be true. Conservators are conservative so we are currently looking at what items might have risks if they are stored in corrosion intercept. Further research is now being carried out on Daguerreotypes and silver gelatine photos. Daguerreotypes, which have a copper-silver combined chemistry, may have an adverse reaction to adding another copper layer.

Likewise, the ability for intercept to reduce tarnishing may have an adverse effect on silver gelatine photos. Caution is advised until further research is done.

While direct storage in Intercept for these items may not be advisable, general use elsewhere in the store room environment will improve quality and have beneficial effects.
