Thanks to everyone who has replied.

I have not been using distilled tap water so I think I will start doing that and then not use the gun for long periods of time. In the past I have not used the ...

What is the best type of glue to use for attaching a thumbnail mineral specimen to the foam liner at the bottom of a perky box? Is mineral tack preferred by some? Thanks.

Jordi, Alfredo, Pete,

Thanks for you advice. I will leave it alone.

Did anyone get photos of the ". . . new blue Albites with Microcline and smoky Quartz from somewhere in China.." that Jordi mentioned. I did not see any in the thread. Thanks.

Mark,

Thanks for the info.

Thanks to everyone who suggested the Super Iron Out. It took several baths in the solution but the results were very good.

David

Thanks!
