Fossil Cleaning with Pressure Washer

[Kjbrunzo]

Dang, those are some huge Crinoids, but i guess a lot of things were huge in the mississippian period

[flyingscience]

Look at my "largest Mississippian crinoid video . The man who owns it made a beautiful edrioasteroid wooden sculpture bowl similar to a crinoid .I will post that video soon !

Are you a Cincinnati DryDredgers member?

[flyingscience]

Kjbrunzo- If you are curious about the video makers click their account and read their self description .

@cornsqueezins We can tell who the idiot is by our account names alone . Obviously this is close to parody because fossils are usualy delicate .Large fossils can be pressurewashed as shown .

at 1;38 you can see a fossil get blasted out of the rock ;)

I'd like to see an archiologist comment on this method! LOL!

[tashtan1]

@CSXer omg thats an awesome ideo to dig lol,funny

[lawnside82]

how many psi?? more or less than 2100??

[flyingscience]

2400psi

[lawnside82]

how many psi is that washer??

[flyingscience]

Its not the industrial strength kind thats dangerous .The wand can be screwed to make fan or stream .Stream having the most pressure .

[BelieveNoGod]

The piece at 5.37 got real nice.

The fossils are so clearly visible.

[gaelicwinds]

you could also use a fan type nozle

[flyingscience]

I have used pressure hoses at the car wash for muddy slabs .

[mindwis3]

Not for delicate fossils ;D

Just out of curiousity, how would a high frequency sonar bath do?

(sorry, i don't know what they're called in english).

I imagine they'd do quite well, but one might need to keep the fossils 'floating' prevent damage to them.

I don;t have one laying about though lol :)

tnx for sharing, lol :)

I think you mean ultra sound cleaning ,I wouldn't know .Air abrasives (baby powder talc)is shot from air pressure guns like sand blasting .

[flyingscience]

Air abrasives have made it possible to remove delicate shale from spiny trilobites with periscope like eyes-its amazing and VERY delicate work.

[mindwis3]

delicate i can imagine, amazing indeed :)

[flyingscience]

My son was cleaning black stains on plastic and didnt need goggles because it was on soft fan setting .Wear goggles when doing stream with loose parts.

[flyingscience]

This very method is almost a parody because fossil cleaning is usually delicate .

[lygoz]

2nd comment and that Mississippi incrineods are cool.

[walt776]

Interesting. I always assumed doing something like that would damage fossils, but I guess not in this case.

[flyingscience]

These are big bulky fossils embedded in hard limestone .Thin fossils in shale would be out of the question .
