Birchwood Casey M24 is a unique brush-on concentrate for blackening or browning of brass, bronze or copper alloys. Produces pleasing US10B finishes on large architectural surfaces, sculptures, or engravings -- on new or reconditioned parts. Color and reaction speed can be controlled by diluting with water. Can be used undiluted for black finishes, or diluted by 10-50% for brown tones or slower reactions.
