damascus,

Turpentine for horse's hoofs? Ah yes, I recall reading about this about forty years ago in James Herriot's "All Creatures Great and Small". I'm not sure if this is currently used like that over here. Kind of like Terebene, which appears to be unavailable. Since I live out here in the sticks (Eastern Iowa) and horses are much more numerous than artists, next time I trot over to my local farm supply store I'll see if they have some.

Thanks for the etchant info, I'm still deciding which may to go, the copper sulphate method I'm considering is the one described by Tony Treadwell.

Thanks
Ken

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
