just picked up an unknown green smooth as glass stone........has been used with oil and cannot get a slurry going when using my synthetic Japanese slurry stone....lapping:O nothing am very inexperienced and have only used oilstones/arkansas over the years BUT what I have seen with coticles is awesome; till I can purchase a coticle could this green stone be repaired to go back from oil to water?..it is a lovely stone and have tried to post pics BUT just can't seem to get them to download here.........thanks in advance for any advice to an ignoramus,
Lou
end before lapping <brown>
