I have a question about what to do with this?
This is a Mihec 45 200gr SWC mold that I have had for a long time. I just finished photographing and doing a database inventory for each mold I own. When I got this one out of the airtight plastic container I store my molds in, it had this weird oxidation in the second cavity and a little bit in the fourth cavity.
What would be the appropriate action to take, to try and treat this? I have a bunch of brass molds, but this is the first time I have encountered this.
It was interesting to me, going through all my molds. I was really surprised by the iron molds. Most of them I slather up with 30 weight oil, and store in air tight containers. But the few that I left dry, were in brand new condition with no signs of any corrosion.
What really surprised me were the quantity of aluminum Accurate Molds and NOE molds that had more than a little rust on the sprue plates. The aluminum molds were in perfect shape, but some of them had significant traces of rust on the top surface of the sprue plate that wouldn't come off with a light brushing with oil and some 000 steel wool.
I bought some indicating 5 gram desiccant bags to put into each air tight container. I usually put two molds in each container. These desiccant bags turn color when they become saturated. I am hoping that storing them with the desiccant bags will reduce the likelihood of surface rust in the future.
Thank you in advance if you have some advice on this brass mold. And if you want a fun and surprising time - go out and document every mold you own. You might be overwhelmed at the number of them (especially the quantities of the ones you forgot you purchased)!
