Is there a 3rd edition version of that spell? Well, a name change is ok with me if it's ok with Shade.
There's a spell called trobriand's crystalbrittle in City of Splendors: Waterdeep which reduces a single non-magical object to hardness 1 and 1 hp/inch thickness.
That's a bit different from the AD&D version which, if I remember correctly, was an area effect spell that affected metal and stone only, but could affect magical weapons and constructs.
