hi,
ive been lurking these forums for awhile but yesterday i ended up coming across something the search tool couldnt answer for me. I purchased a big wooden box off a woman that had all sorts of railroad tools, lanterns,saws,etc. Well in the box i found two interesting stones one was definately a nice dual coarse/fine black/white stone. but the other is this one. its soft almost like its a soapstone and i guess its very likely that it is a soapstone. but it looked to have been used as a hone/(lapstone?) it is all one piece looks almost a dirty white when dry. when you wet it it looks like forgive me here, but it looks like the offspring of a wad of fiberlass hair and a blue colored fruitcake minus the fruit haha. its really hard to explain. the stone is fully of crystalish stringy structure and looks encased in a type of resin or epoxy. but the stone is most definately not manmade. it has a waxy/chalky similar to soapstone feel. its probably something useless, but my luck its pure asbestos. anyways anything people could help with would be appreciated..i wish i could get better pictures but at the moment this is the best i can do. unfortunately the pictures dont show the translucent properties of it. ok thank you and the forum is great.
<edit> Forgot to mention both stones a pair of nail scissors, rotten cotton square, and an old jackknife were in a moldy leather pouch but were definately used together or i wouldnt have assumed it a sharpening stone. It also is really heavy for its size </edit>

:confused:

Hi,

width?
height?
weight?

update: grab a magnifier and start going through the rock key to identify the rock type

its actually almost identical in consistency to soapstone, it turns muddy quickly and the powder is fine as talc.

it measures 6.5"x1.25x1.25, and im not sure on the weight but in a hand comparison i found it to be closest to brass in weight.

someone mentioned coloring compound and very well may be correct but the powder is white so i dont know if that is common for coloring or not.

it seems useless for sharpening anything, im not known for my finesse but i could not make more than 10 strokes across it before a slight angle change gouges the surface all up,

when i first took it out it looked like it was getting thin slices taken out of it as it was covered in knife gouges and black grease (almost everything was covered in a black tar like grease)....

I dont think its anything of value i am just truly fascinated by old time tools / tech, and recently rail so was hoping someone would be familiar with it. Ill go look thru the rock key and see if i get any leads. thanks eveyone

[Edit] Rock Key tells me it is marble and it could be correct but i had never noticed marble to get so dark when wet, but hey could this guy have been carving something into it? its probably not recommended to carve marble with a jacknife but he was a rail worker not a rocket scientist... ill settle for that [/Edit]
