Noob Looking For Help.

[nathanzx10r]

Just purchased this set up and would like some help trying to find the best material to use.

I have never used this type of tool before so I am pretty much a noob when it comes to this.

After reading the forum, people use so many different medias that it was a little overwhelming.

I will be using it on Green River matrix, utah trilo matrix, and some local sandstone and shale in the NW.

most of us use dolomite and sodium bicarb. The Europeans also use iron filings, which may be hard to find here. Are your Green River fish from the 18 inch layer or the Split Fish? Split fish (yellow matrix, brown bones) are too fragile for any sandblasting. I have done 18 inch fish (darker bones, gray hard shale), but I can't remember if I used bicarb or dolomite.

...The Europeans also use iron filings...

I have heard mention of the use of powdered iron by UK preparators; it is apparently far less aggressive than iron filings.

I pretty exclusively use sodium bicarbonate since it is easily had at the supermarket.
