Thread: a junk store RED

so I run in the local flea market to get a couple more traps - a whistle pig is destroying the garden - anyway, like always I ask the lady if any razors or hones came in and she shows me this. At first I think its a cut piece of floor tile. Its 5 x 2 x 1/2 and a little off square. The density is unusually low, I've cut red floor tiles and this thing is way lighter...noticeably lighter than a swaty. fool that I am I carried it home for $6 thinking 'that's not a hone...but wait maybe it is'...

It has circle saw marks on the side and straight on one end. under my handheld 60-120X I see what looks like quartz crystals in a CNAT or welsh slate. These pics from the usb scope don't show it that well. Its not very soft, had to hit it on the DMT325 pretty hard to build a red slurry. It almost looks like pipestone-catlinite, I'll have to measure the density after a while.

Get some pictures up in natural light of it lapped, wet and dry.

It might be something fun like a la lorraine but I can't tell with those images.

here it is wet.

grapes = Norton/Cynthiana

yes, that is a monolithic dome in background.

I measured the density to be 1.186 g/cm^3 with home equipment probably measurement uncertainty 0.1 or so. Very light, probably not catlinite/pipestone that is easily carved this is too hard to lap easily. Probably not even a hone, it is the color of a brick.

Just having fun, but I will put a razor on this after lapping.

Looks a bit too red for a La Loraine, mine are more purple or brown and on the soft side, that slurry easily, could be the photo or some other stone.

It is the size of a razor stone,

Compare the stria, not the grit on the stone. Hone a razor on your highest grit stone, then the toe half on the red stone and compare the two sets of stria.

This is crazy. I was wrong about hardness. DMT C wasn't making any progress, but 220 wet dry on the granite countertop ate it up in a minute lapped flat.

Then I put an old razor that has been sitting for 6 months on it and this thing has the most sticktion ever. Just looking at it you would think extreme course but after 30 laps looking at it under 60x handmike it is smooth as a nani12k and treetopping like crazy.

It looks and sounds like a type of brick to me I can't remember what type though. My grandfather used bricks for years to sharpin knives. But I could be wrong.

Kinda funny how there are things the DMT eats alive that sand paper won't touch and vice versa.

Looks like an older piece of ceramic tile that we had for our kitchen backsplash. Exact same size, color, and texture.

Last night I shaved with a razor touched up on this thing that looks and feels like a slice of a red brick. Its been at least 6 mo inactivity for this razor, it was due as last shave was not the best and it got put in line for work.

Using only water, the razor stuck to stone like nothing I've seen before. Looking at the bevel afterwards 60-120X I was surprised at how clear it was, I expected lots of scratches. Straight off the hone to maybe 50 laps on clean leather and I got a fine shave.

This morning I look at the lapped side. Whereas unlapped looked like quartz crystals, lapped side looks like a weave of fibers exposed by removal of the binder. I know there are lightweight natural rocks, but I'm thinking this is man made. Perhaps it was a recipe using hardened rouge as the abrasive.
