So I've been collecting Grenadier and Ral Partha figures from 1970s/80s for a couple of years now and have built up a sizable collection. I take a certain amount of joy in picking up lots of loose miniatures that I can obtain locally and see if I can identify them and put old sets together--eventually the plan is to display completed sets in shadow boxes on the walls of my office. I've noticed that some have shown varying degrees of oxidization and will be taking precautions to remove and prevent further oxidization. For a while now, my storage solution has been to place each figure into its own small plastic bag on which I record basic provenience information. I am worried, however, that the small airtight bags might promote further oxidization. I was wondering if anyone else has run into the problem and perhaps found a suitable solution. My current idea is to pick up cardboard cotton-lined jewelry boxes and hope that they are airy enough to allow the miniatures to breath and hopefully prevent further oxidization. It might just be a crap shoot as my research has suggested that early lead mixtures could vary wildly with some casts simply have more favorable ratios than others. Either way, I am hoping that I might help preserve some of the history associated with early miniatures associated with the rise of roleplaying games, etc.
