My first blog entry.... (with Pics!)

12th Apr 2008

Hello All!

I recently began a blog on my website and I thought it might be fun to start one on mindat as well. However, I have two previous entries already and, before I started posting here on mindat, I thought it would be a good idea to bring everyone up to speed before I post my next installment (which will be sometime this week). Below I have simply pasted the blog as it is on my website.

The MineralMan Blog



Since we had so much fun with our Tucson Blog, Mandy and I thought that it might be fun to begin a weekly blog! This will be an informal vehicle to provide you with additional information about weekly listings, additions to the site, articles, research, and current events. This line of work takes us on so many fun adventures and exposes us to so many interesting things that we figured it would be a great idea to document and share them in some way. What better format than this?

Lulu Temple



This week Mandy and I went to a small regional mineral show in Plymouth Meeting, PA. The show was held at a place called the "LuLu Temple" which is a Shriners' "mosque" near Philadelphia. We have been going to this show for years and it is always a good place to find great material.











Charles M. Wheatley


Pennsylvania Uranium Minerals Display




While there weren't too many displays at the show, there were a few things that caught our eye. One of those things was this picture of Charles Wheatley, the proprietor of the Wheatley Mine (as well as its namesake). The Wheatley Mine was originally opened around 1850 and was closed for good by 1920. It was a lead and silver mine and is perhaps best known among collectors for its classic pyromorphite specimens. Charles Wheatley was also a mineral collector - I am sure owning a magnificent pyromorphite locality was a great advantage in terms of trading!!! We aslo saw a display that featured several radioactive specimens and a book on radioactive specimens of Pennsylvania. Much to our dismay, there were no actual radioactive specimens from Pennsylvania in the display. But, as luck would have it, we found a francevillite from Pennsylvania at the show - how about that?!








Amethyst - Deleware Co., PA

Calcite- York Co., PA



And of course, no respectable Pennsylvania show would be complete without a general display of Pennsylvania minerals. Of particular note were this amethyst from Delaware County and this calcite specimen from York County. It is difficult to fully appreciate them from these photos as there was no adequate lighting on the case. However, the amethyst was doubly terminated with pronounced, saturated violet color at each end and the calcite crystal was large, lustrous, and had significant clarity.









Here is a view of all the action at the show. Do you see any familiar faces in the crowd?



Where's Mandy?







Iron Stain Removers

Products used for clean up and prep



Aside from attending the show, Mandy and I also looked at a private collection this week. All told we acquired a few hundred specimens this week. These specimens will be making their way onto the site and our ebay auctions in the upcoming weeks. However, it is not just a simple process of acquiring a specimen from an old collection, photographing it and selling it. Many of the specimens need significant preperation and cleaning before we sell them. We encounter specimens in all kinds of conditions. I thought it might be fun to share our techniques and some of things we've learned over the years. These are some of the more useful products that we use for various purposes.



  • "Rust Stain Remover" - The active ingredient is hydrofluoric acid. This product is used for, among other things, removing iron stains from specimens


  • "Iron Out" - The active ingredient is oxalic acid. This comes as a powder that is mixed with water in varying strengths. As the name implies, this is also used to remove iron staining


  • "Weiman Wax Remover" - This product is the best thing to use on very old, stiff, dried out, gooey, or otherwise decrepit mineral tack. Without this product, one risks either damaging the specimen or winding up in a situation where all the tiny bits of ancient mineral tack remain impossibly stuck in every nook & cranny of the specimen. After carefully removing any large mass of tack if possible, the specimen is left to soak in the wax remover. After a few hours the tack is dissolved and can easily be brushed away with a paintbrush. This product has been shown to be very safe in my experience and does no harm any species I've used it with - although I have never tested it out with water soluble species


  • Acetone - Acetone is the classic solvent for cyanoacrylate glues (like krazy glue, etc.) and other glues other than elmer's that are not water soluble


  • "Goo Gone" - Goo Gone is our "go to" product for removing relatively "fresh" mineral tack that is being stubborn or stuck in delicate areas (for example, a thin gold or silver specimen that you do not want to bend) or "gooey" areas left behind by stickers of any kind










Pyrite with Rust




Here is an example of a commonly encountered situation - iron oxide staining. In this case I have a pyrite specimen with minor hematite on the underside, from Elba, Italy. There is some minor iron staining on some areas that I hope to remove using the oxalic acid (Iron Out). I start by dissolving a small amount of Iron Out in a small amount of water. Since I am only planning on treating a small area of the specimen I will try to use a Q-tip to address the area rather than leaving it to soak in the solution (which is often needed for more extensive iron staining). I leave a few drops of solution to sit on the areas of iron stain. After a minute or so, I apply some pressure with the Q-tip and am able to rub the stain off with much success.







Before

After



On the left you can see that the pyrite crystal has a significant area of iron stain on the largest face. After treatment with the oxalic acid (in the form of "Iron Out") the pyrite crystal shows its gleaming metallic brilliance.








Rhodochrosite

Rhodochrosite



An old, cruddy, box containing a barely visible mineral specimen. This is an all too common sight for us. Unfortunately buying "old" collections means buying all the "old" containers, mountings, and boxes that go along with them. This is typical example of what I have to do before a specimen goes up for sale.








Rhodochrosite

Rhodochrosite



Upon removing the specimen from its old plastic box it is clear that the specimen is affixed to the styrofoam base with something other than mineral tack. I then carefully remove the majority of styrofoam with a small pair of nippers (small nippers are always close by as they are excellent for quick minor trim jobs). Careless removal of styrofoam, by just ripping a specimen off of it, has resulted in more than just one broken specimen.








Rhodochrosite

Rhodochrosite



With most of the styrofoam removed, one can easily see what kind of glue we are dealing with. In this case it is clear to me that it is not a water-soluble "Elmer's" type glue, which usually has a slightly milky appearance. So I know I need to use acetone to remove it from the specimen. However, if you are not sure you can always try water first and if it doesn't work then dry it off and soak it in acetone. I have found that starting out with acetone on a water-soluble glue can make things more difficult for some reason.








Rhodochrosite

Rhodochrosite



After letting the specimen soak in acetone for a little while, I remove it from the solution and use a stiff bristled paint brush to gently brush away the softened glue and remaining styrofoam. This process is repeated until all the glue is gone.








Rhodochrosite




After all of this I gave the specimen a gentle cleaning with water and very soft brush to remove any old grime and remnants of the glue cleaning process. Here you see the end result - a lovely rhodochrosite specimen from.... a rare locale! I am giving a $25 dollar credit to the first person to successfully guess the correct locality. The locality only needs to be accurate down to the general region of that country - i.e. the equivalent of province, prefecture, state, etc. Just email your quess to mineralman999@yahoo.com

Possum


To start things off, this is a picture I have been wanting to share for some time. One night while Mandy and I were working, we noticed this cute little fella staring at us through the window! This guy is literally just inches away from our window. He was just quietly perched there, casually looking in at us. He stayed there for a good hour or so - just watching us working on our mineral related tasks.










Drawbridge - Manasquan, NJ

Inlet - Manasquan, NJ



These two pictures are from right near our house here in Manasquan, New Jersey. On the left is the old Draw Bridge. It is on our street, about a block away and it is over 100 years old. On the right is a scene looking out the Manasquan Inlet to the Atlantic Ocean. When I was a teenager, I caught baitfish in these waters for sale at a local baitshop.








On March 1st & 2nd, the New York Mineralogical Society in conjunction with Tony Nikischer of Excalibur Mineral Corporation held mineral show in New York City. Here is a picture of Mandy riding on the train. The train takes us from within walking distance of our house, along the coastline, right into the heart of Manhattan.

Times Square

Mandy with mineral superstar, Alfredo Petrov



Here is a quick pic from Times Square on our walk from Penn Station to 57th Street where the Mineral Show was. One of the dealers at the show was friend and mineral genius extraordinaire, Alfredo Petrov. We are always excited to see Alfredo. His selection of rare species is a constant source of excellent and fascinating material. In addition to his fantastic material he has been an invaluable source of information and insights for us over the years.












Fluorite Caterpillar

In closing, I'd like to leave you with this picture of a "fluorite caterpillar." We sold this specimen several years ago and today it resides in the collection of Charlotte Sussman's Animal-Like Specimens along side the famous, and admittedly cuter, "Lavinsky Bear" schorl tourmaline specimen. This picture was lucky enough to be a "Photo of the Day" on www.mindat.org!

Super Iron out is NOT oxalic acid, but rather a mixture of sodium hydrosulfite and bisulfite and citric acid and sodium carbonate.

Thanks David, I got it mixed up - no pun intended! :)

The possum photo is great! After watching you two for an hour, he probably knows more about minerals than some casual collectors do.
Your fluorite caterpillar is one of my favorite mineral pictures too.

Thanks Alfredo! We also have some stray cats that we began feeding. That same possum has developed a taste for cat food and now he visits us nightly. However, I think he came to the conclusion that watching us play with rocks was hardly exciting at all since that was the only time he ever did it. And thanks for your compliments on the caterpillar :)
We'll see you at the Franklin show, right?
