I am getting ready to add an air eraser to my prep equpiment. My question is what would be an appropiate media to use for fossils. Mainly to clean up white river and green river material. I have read the bake soda will do the trick, but was wondering what you guys use

Hi all, I have been searching through posts in the forum about various types of abrasives, and I can't seem to find a comment anywhere where someone breaks down the pros/cons of the different forms of abrasive and their microns. Of course I realize everyone has their own preferences, I am just confused as to the objective benefits of what looks like the three main types of abrasives: dolomite, aluminum oxide, and just plain baking soda (besides the fact that baking soda is more delicate.) The Paasche Air Eraser comes with 240 micron aluminum oxide, but that seems to be a little extreme for fossil preparation, is there an appropriate time and place in which I could use that? What would be the max (or even a general range) micron of either dolomite or aluminum oxide that one would recommend I use for 1. Green River fish, 2. trilobites, 3. ammonites, or 4. just general fossil clean-up?

Suggestions For Breaking Down Some Matrix Please!?
fossilized6s posted a topic in Micro-paleontology
I'm try to break down some hard micro matrix from the ATCO formation in TX. Its a rock solid clay, almost sandstone. Now there are some very tiny micros in this stuff and i don't want to cause any abrasion to them by just throwing them in a hydrogen peroxide solution. Do you guys suggest Muratic acid? Vinegar and baking soda? Or Hydrogen Peroxide? And what are some ratios you tend to work with? And how long do you soak them? Any and all help is appreciated by this micro noob!- 14 replies
