How To Choose and Use A Marking Stamp: Bent vs. Straight
Confused about which marking stamp to use? Here is a quick how-to on the differences between bent-shank and straight-shank marking stamps and how to use your stamp to get the best result for every piece, every time.
Beware, if you are new to using marking stamps; you should not expect to buy your first stamp, grab any old hammer and *POW* whale away on one of your beautiful finished pieces of jewelry. For best results, we highly recommend practice, practice, practice and more practice. Use scraps of inexpensive sheet as well as brass practice ring blanks before attempting to mark one of your designs. The mark cannot easily be erased and redone; it must be done right the first time.
Also, stamping should be done on work before any stones are set to avoid any damage, misshaping, cracking or loosening of the setting and/or stone that can be caused by the sudden stress of the hammer blow. For best results use support such a bench block or an anvil and a brass mallet to strike the stamp.
STRAIGHT vs. BENT
Straight stamps have both a straight shank and a straight-across, flat surface at the tip. These stamps are ideal for quality and hallmark tags and for any other flat, easy-to-access surface.
Bent (ring) stamps are ideal for stamping the inside of a ring or other curved surface. Not only is the shank bent to allow you to place it inside the ring and still hold it perpendicular to the surface, but the tip is also curved, cut at a radius suitable for the curvature of most ring sizes, to hold the characters cut into it at the ideal angle for a clean, effective strike.
HOW TO MARK WITH A STAMP
1. The piece to be stamped should be placed on a supportive polished steel surface such as a bench block or anvil.
2. The reverse side of the surface to be marked should be fully in contact with this surface so that the object is supported completely when the stamp is struck, minimizing the risk of a distorted result.
3. The stamp should be held as perfectly vertical as possible.
4. Strike the stamp cleanly and forcefully; one well-placed blow with an appropriate hammer or mallet should do the trick. We recommend a brass-head mallet or the GersonHammer.
If struck twice, the result will almost inevitably be a visible double-strike with the stamped image showing a blurred "ghost" image or indistinct and uneven marks.
5. Strike the stamp hard enough to make a mark sufficiently deep that it will not wear away easily over a short period of time.
How To Quality-Mark Precious Metals
Here's how to make sure your customers know what they're getting . . . on the day of the sale and for years afterward. Customers feel more confident and appreciate the openness when you take steps to ensure that they know what they’re getting when they buy any precious metal from you--it builds a priceless trust in your business. Jewelry made from wire, sheet or casting pieces with a definable precious metal content can be legally stamped with that information as well as with your maker’s mark.
Be sure to put these designations and your maker’s mark on the platinum, Argentium, sterling silver, fine silver, gold-filled and silver-filled jewelry you sell. Customers will know that you care about and guarantee their precious metal purchases.
Choose a metal stamp marked with the quality of the metal your piece is made from. For tags or other flat pieces, choose a straight stamp; for curved pieces such as rings or bracelets, choose a bent stamp. This will ensure the most effective access to the surface you want to stamp.
If you are stamping a tag, select a quality tag that's appropriate to the jewelry item you'll be placing it on.
Set the jewelry item or the selected tag on a steel bench block on a sturdy surface. Position the jewelry item or tag on a sturdy surface where it is well-supported and that are to be stamped is uppermost and accessible to the stamp.
Set the stamp on the item or tag where you want to place the mark. Using a brass mallet, strike the stamp firmly and directly to deeply and legibly mark the metal.
If you marked a tag, attach the tag to your jewelry item with a jump ring. Solder the jump ring closed to secure it in place.
