Hi Ot, I was just looking on ebay and came across some mineral tack that is non greasy. I have not used it before but am wanting to purchase some also. heres the web site- www.ebay.com/.../Mineral-Tack-Specimen-Mounting-Putty..
You might want to get a better opinion though.
Cheers!

I have had good experience with using a tack that is sold as "Tetningslist " for bathrooms at Clas Ohlson,in Norway their product nr. 34-4264 , see [www.clasohlson.no].
.

I am looking for mineral tack also but the guy on ebay wants $6.00 for shipping which is more that half the cost of the tack. So what knind of a deal is that?? Can anyone help????

Take care and best regards.

I'm afraid that tack with NO oil/grease doesn't exist...
I've definitively switched to hot glue: no grease, better looking, cheap and easy to buy in each hardware store / big store.

Agree with Luca, every mineral tack, whether specialist for minerals or not, contains some oils. There are some that contain less oils, but they are the ones that are more likely to dry out and crack after a few months/years.

Regardless, if you use tack to secure important specimens, check and if necessary replace it every year or so.

Hot glue is much maligned, mostly due to ignorance of how to remove it (it's much easier to remove hot glue from most specimens than stubborn dried up mineral tack remenants.

Seeing this discussion has led me to ask two questions. First, how does one remove hot glue from delicate minerals which have been mounted on a base of whatever? Second, how does one remove the oil from "mineral tack" that has wicked up into porous specimens? I am still struggling to remove these unsightly stains from a collections of micromounts I purchased. So far I have tried soaking in isopropanol and acetone with minimal results.

Usually you can easily remove hot glue wetting in with some drops of alcool (better white aka not coloured alcool of course!).
For oil or tack residual from delicate specimens I think you need some kind of solvent but, sorry, I can't help you in a better way.

This stuff has no oil or residue but t will stick to the specimen and sometimes leaves some of the wax in the cracks and vugs where it was mounted. I never tried to remove any of it with heat or chemicals since I mount my specimens for keeps. Heres a link:Museum Wax

I have tried the wax used by printers to do "paste-ups". It works well with any size specimen, but I think it is a little sensitive to temperature, If it gets cold the specimen may separate. Otherwise, it does not dry out or discolor. One can soften it by kneading and it is easy to use. For mounting micros, I usually use Sorbo white glue that is used by librarians. It is a little more viscous than the usual white glue, doesn't discolor, dries fairly quickly, and is reliably permanent.

I have been using blue "poster putty" made by Duck. It is the best I have found. Does not leave grease spots and does not dry out like the off-white brands. I have not seen it at Staples, but Office Max has it near their poster boards.

To remove mineral tack residue or oil from mineral tack from a specimen you can use white spirit og diesel.
