Hello everyone! So i have been hard at work. Last time I damaged a couple of fossils because the PSI on the sandblasting machine was too high while I was working on removing matrix directly off the fossil. This time I learned that higher pressures like 20 or 40 PSI can be useful for removing large amounts of matrix that are not directly touching the fossil. While lower pressures like 5 PSI are useful for removing small amounts of matrix to expose details of fossils. Also it is a good idea to wait to expose details until the entire fossil is mostly exposed and only detail work remains. Thi
Hey guys! So I thought that I would start a new blog here. I have been looking for videos and other instructional material on line for how to prep / clean a fossil and have not found much. Google did not seem to be to helpful in this matter. I did find a few more things on this forum and they were very helpful. I learned what materials I needed and some techniques of how to clean fossils, but nothing like "Make sure to do this.....", "don't do this....". So I was able to gain access to my School's Palio and geoscience lab, and we put together a fossil prep lab. Now it may not be as fancy
Hey fellow friends, Does anyone have a plan of building a sand blasting box cheaply. I'm a forensic science student and don't have much money. This is my first time making one and appreciate any help that can be given Thanks everyone Scott
TMadam posted a topic in Fossil PreparationThank you all for being incredibly helpful. I have a Paasche Air Eraser on the way and I have seen pictures of people using Hyperdermic needles as nozzles but I haven't seen how they do it or where they get the needles. Can someone point me to a tutorial? I have checked Google and searched this forum, the best I have found is the end result of what it looks like. Thanks, Adam
