How to Maximize Your Gold Recovery Returns


Dust in your store can reap unexpected rewards. In day-to-day activities like buffing, polishing, grinding, and so on, fine metal dust spreads around your workspace.

Collecting this accumulation of dust and precious metal amounts to a considerable return that can put money back in your pocket.

Here are a few easy ways to get the most out of your gold recovery:

Keep It Inside

A bench mat is essential to keeping your workspace clean and tidy. This can help to collect small bits of precious metals and prevents debris from falling onto the floor and getting scattered.

Also, the sticky adhesive of a Gold Mat placed at the entrance/exit of your work area will capture bits of gold and precious metal, helping you gather the tiny fragments on the bottom of your shoes.

TIP: To maximize your returns, keep different grades of metal scraps separated for refining.

Keep Your Sweeps

Keep cutoff/separating wheel pieces, old flex-shaft buffs, brushes, etc. and throw them in with the floor sweeps.

  • Designate filings and trimmings from stone setting and seat cutting, for example, as clean filings.
  • Use your bench mat to collect finishing wheel debris, buffings, pumice wheel, and other pre-finishing wheel debris. Keep this separate from your clean filings.
  • Keep old buffing wheels, used sandpaper, and anything else you think might contain gold. It probably does!

Buy a Dust Collector

Rather than a traditional vacuum cleaner, use a Variable Speed Dust Collector with disposable bags to vacuum shop floors. This ensures the collection of 99.9% of debris and traps particles (down to 0.3 microns in size) in its collection chambers.

Save the filled bags, and keep them with your floor sweeps. These bags can contain a substantial amount of gold in the form of small solder snippings, filings, cut-off disc powders, small pieces from ring sizing, etc. that can all be sent to your refiner.

TIP: Vacuum your buffer daily. It helps keep the shop neat and decreases buffing dust from falling to the floor.

Don’t Forget the Ultrasonic Solution

Use a rinse bucket to rinse items coming from the ultrasonic. Also, bottle your old ultrasonic solution, settle it out, and pour off the clear top liquids. The sludge can be dried out and returned to your refiner with the buffing dust. Yield is typically about the same as buffing dust.

Drain Sweeper Installation

Don’t let your gold wash down the drain!

By investing in a drain sweeper, you can capture precious metal sediment that would otherwise be flushed down the pipes.

A Stuller tools study revealed that after nearly six weeks of using the drain sweeper, 0.082 ounces of gold were recovered, equating to roughly $77.67 at $947.25 gold. A product like this will pay for itself.

Crucible Care is Crucial

If you cast, rinse out your quench tank/bucket and pour off the suspended used investment.

  • Keep the bottom sludge and put it in with the floor sweeps. This can contain a good amount of gold debris.
  • Save old melting and casting crucibles and return with the floor sweeps as well; these also contain a good amount of finely divided gold particles.

More Ways to Maximize Gold Recovery Returns

  • Save your filters, including those from air conditioners, dehumidifiers, and dust collectors. These can contain a good amount of fine gold dust from buffing.
  • Segregate gold by karat from ring sizings and such. If kept separate, you can remelt and roll these pieces out to make sizing stock, wire, etc. You’ll get a higher return if the karatage of your gold bits is known.
  • Save gold-filled and gold-plated pieces, along with silver watch batteries (throw out NiCd batteries; they have no value). These may have a small amount of gold, but anything saved helps pay bills.

Approximate Gold Recovery Yieldsgold recovery

Clean Filings: Approximately 40% fine gold by weight

Dirty Bench Sweeps: Approximately 5% to 20% fine gold by weight

Buffing Dust: Approximately 2% fine gold by weight

Floor Sweeps (including vacuum cleaner bags): Approximately 1% by weight

Celebrate National Worship of Tools Day

If you’ve paid attention to your calendar and love obscure holidays, you may be ahead of the pack and know what today is. But if you don’t know, it’s March 11, which means today is one pretty fantastic day:

National Worship of Tools Day!


While we love to splurge on new bench tools, you should also keep the ones in your workspace in working order. Here are some simple ways to extend the life of your tools to keep your workflow moving, just in time for National Worship of Tools Day:

Clean Regularly

Taking time to thoroughly clean what you use most at the bench will help protect against long-term damage. It doesn’t have to take a long time, but getting in the habit will go a long way.

This includes checking any blades or smaller pieces that contribute to your machine working correctly. It also won’t hurt to polish those blades and use a soft wire brush to clean between the teeth. Add in dusting time to sweep away filings as well as general cleanup.

  54-4430       54-4425            16-0551       16-0510

Lubricate Tools

Whether it’s to extend the life of your tools or reduce friction and heat buildup, proper lubrication is crucial. Friction from using the tools can slow down gears, dry out belts, and more. Use tool-appropriate lubricants to reduce friction, prevent dust particles from getting in shafts and joints, and more.

                34-2279       21-0740             26-1003

Keep the Habit Going

Cleaning an item once or twice is great, but forming the habit of adding maintenance to your work routine is key.

Want a more detailed listing of how often to care for your tools? Create a schedule for yourself to ensure you stay on top of maintenance. Here’s an example from our bench team of some small things you can do frequently to keep your tools happy:


Handpiece: Check both outer and inner springs. They shouldn’t bend more than 45 degrees. Replace springs as needed.


Flex shaft: Check the motor brushes and shaft to ensure they are working properly. Oil the sheath. A well-running flex-shaft is like a smooth-running engine.

Ultrasonic: Check water levels. Collect the sludge in the tank for refining. Wipe it clean.

Every Other Week

Bench: Clean your bench. Collect and separate sweeps. Use a refining bag for clippings and a trash bag for dust.

Polishing Unit: Empty and clean out the bags. (The three filters in this unit need to be changed every six to eight months, so schedule accordingly.)

Dust Collector: Wash the pre-filter, which is wrapped around the unit.


Files: Use a wire brush to clean and collect debris from files.

Plating Solutions: Clean and filter the solutions. Remember to keep a cap on the solutions at all times.

Every Other Month

Dust Collector: Wash the large filter.

Steamer: To clean the unit, blow it out to 5 psi and release. Check the glass tube and washers, which can thin out from running water through the machine, and replace if needed. Wear safety glasses and gloves when performing this maintenance task.

So, how are you gonna celebrate National Worship of Tools Day? Have any tips and tricks for extending the lifespan of your bench tools? Let us know in the comments below!

Tumbling Media for Jewelry: Finding the Right One

tumbling media

You’ve heard of tumbling media for finishing jewelry; you’ve probably even used it. But there are many kinds, and each one has characteristics that make it better suited for one type of project, finish, or tumbler.

This handy guide, featured in From the Bench’s Repair Issue, will help you make the right choice and achieve better results with your jewelry.

What’s the Difference?

Tumbling media abrades against your jewelry to remove unwanted material. Applications include deburring, polishing, burnishing, and removing fire scale. Create your desired surface finish by choosing media based on characteristics like size, shape, and composition.

Tumbling Media 1: Stainless Steel Pins

Stainless steel pins leave a semi-bright finish in a short amount of time, perfect for use right after casting. Use stainless steel pins with a magnetic tumbler, along with Stuller’s finishing soap.

47-5055 stainless steel pins


Tumbling Media 2: Treated Walnut Shell

This media can be used on all metals to produce an excellent mirror finish. Use it in a vibratory or barrel tumbler.

47-5216 treated walnut shell


Tumbling Media 3: White Pyramids

These plastic, pyramid-shaped media have a medium-cut surface and produce a very fine cut surface conditioning. They’re best for soft metals, to leave a smooth finish with little shine. Use these in a vibratory or barrel tumbler.


Tumbling Media 4: Stainless Steel Mixed Shot

Stainless steel shot is rust- and corrosion-resistant, requires no special storage, and is ideal for use in wet, flow-through systems. Used in a vibratory or barrel tumbler, this stainless-steel shot leaves pieces bright and clean, burnishing metals to a mirror finish.


Tumbling Media 5: Porcelain Balls

Because of their shape, 2-mm porcelain balls impart a single point of contact, leaving a very fine finish to almost any area it reaches. It’s very popular for delicate parts, fine-edge blanking, and precious metal burnishing. Use them in a vibratory or barrel tumbler to create a bright finish with less distortion.


Tumbling Media 6: Brown Pyramids

These plastic, pyramid-shaped media have a medium-cut surface and produce very fine surface conditioning. These pyramids are best for soft metals, to leave a smooth finish with little shine. Use them in a vibratory or barrel tumbler.


Tumbling Media 7: Ceramic Polyhedrons

Ceramic is the heaviest tumbling media and the fastest finisher. Its polyhedron shape is great for grinding and polishing hard metals. It’s also good for deburring machined, casted, and fabricated parts. Use it in a vibratory or barrel tumbler.

Wow Your Customers With These Watch Polishing Tips

Watch Polishing Tips Blog Header

“Wow! My watch looks great!”


Don’t you just love to hear those words from your customer after you deliver their watch repair? A customer’s first impression of the services you’ve rendered often sets the tone for the rest of the season. A great looking polished and refined case and band seems to validate the cost of your customer’s watch repair. After all, the exterior of the watch is all your customer gets to see. So in turn, your customers ultimately determine the acceptability of your work by its final exterior appearance.

Of course, it’s most important that all technical aspects of the watch movement are correct. After all, a great looking case and band will not cover up poor technical workmanship. On the other hand, however, a precisely performed watch repair installed in an unpolished or dirty case makes the entire job appear halfway done.

Here’s how to light your customers’ eyes with these simple watch polishing tips—

Beau Allain’s Top Watch Polishing Tips

Remember, plated cases need to be cleaned in the ultrasonic and not buffed or polished. Here are a few of Beau’s top watch polishing tips—

  • Keep in mind that you never want to over polish. It affects the look of the watch, and you can’t undo it.
  • Before polishing a two-tone watch, determine if it’s plated otherwise you’ll polish off the gold plating. A high end, two-tone watch will be stainless and gold — either 14K or 18K — eliminating this concern.
  • I like to polish with a 11/2” muslin buff (17-6431). It has good tension and the width means I can apply the polish with one side, then remove the polish with the other side without changing buffs.
  • When you’re polishing a satin band, I like to start with a lower micron buff, then come back with a Bergeron Satin Wheel (17-8743).

Keep it Crystal Clear

As a final thought, we find that people who do the best jobs in their professions do the little extra things better than anyone else. So here is an often-overlooked detail. How about the scratches on the watch crystal? Many times that part of the watch is neglected. And, after all, it is the place we look to actually see the time. Do you polish the crystal? It is the extra touch you can give to make the customer’s first impression one they will remember and tell their friends about. Try the Crystal-Kleer (Re-New-All) Plastic Renewer (47-3100) and the PolyWatch Scratch Remover (64-5100) as good scratch removers for all of those plastic crystals.

3 Simple Steps to Achieve Perfect Jewelry Polishing

If you have the typical shop, chances are pretty good that you have a multitude of people using jewelry buffs and polishing compounds with somewhat reckless abandon. Without proper organization, often the wrong compound is used on the wrong buff, and then you’re left with a pile of contaminated shop debris.

If this sounds familiar to you, then we invite you to try this system to preserve the life of your buffs and compounds. In turn, you’ll provide superior finishes for your customers and hold on to a little more of your sanity.

Stage One

Begin with heavy scratch and scuff mark removal using your treated muslin buffs. They are chemically treated and stitched to provide long wear. Mark them on both sides with the number one to ensure your buffs remain separate from one another.

Tripoli vs. Bobbing Compound


A coarse cutting compound to remove scratches and surface imperfections. All-purpose Tripoli cuts similarly to regular Tripoli but leaves a brighter finish. Platinum Tripoli is specially formulated to remove scratches from platinum, chromium, stainless steel, and other hard metals. Tripoli compounds normally contain Tripoli, which is a slightly softer abrasive when compared to Bobbing Compound and gives more color.

Bobbing Compound:

Aggressive on soft metals such as gold, silver, aluminum, and brass. Adheres extremely well to buffs when using laps and bristle brushes. Fast and heavy cutting. Slightly more aggressive than Tripoli, Bobbing Compounds remove scratches and result in a dull finish.

Stage Two

During this stage, we’re taking the metal from a dull luster to a high luster. For this stage, try white muslin buffs that are stitched (17-5715). There are a variety of compounds for this stage, with green rouge (47-3274) being the most common.

Mark all buffs with a number two boldly on both sides. And, again, keep these compounds and buffs all together.

Know Your Buffs

Muslin Buff:

Finex muslin has a very tight weave and is very soft. Excellent for use on all rouges.

Cotton Buff:

Mid-grade softness for delicate surfaces to produce a nice final polish. We suggest TPB Medium-Grade buff (47-3228), followed by STV Soft Cotton Buff (47-3229) for a two-step polishing on fine watches and delicate jewelry. Apply light pressure at a low 1800 RPM speed.

Flannel Buff:

The softest Luxor buff made of white flannel, scraped on two sides, and extremely versatile. This buff can be used with Avivor, Oras, as well as Luxor White, Yellow and Orange polishing compounds. This buff gives an ultra-high finish and is especially effective on Gold, Titanium, Platinum, and Silver.

Stage Three

Final buffing consists of bringing a piece of precious metal to full brilliance accomplished by using loose buffs (buffs that are not stitched, usually made of muslin, ex. (17-7726). There are many compounds used in the final stage, often left up to personal preference. Try our Picasso blue(47-3246) on your white metals and witness what brilliance is all about.

Before you do, though, don’t forget to mark your buffs with the number three, and store them with the final buff compounds in your Stage 3 container.

Here are a few quick tips for jewelry polishing


Quick dos and don’ts for jewelry polishing success: 

DO always use enough polishing compound on the wheel and recharge frequently.
DO always clean a piece between cutting and buffing operations to avoid contamination.
DON’T polish directly against a corner since it will round off. Start with the flat surface against the wheel and draw it out to the edge of the wheel.
DON’T polish down into a “V” since the buff will conform to the shape and cut a groove into the surface. Instead, polish against the point of the “V” and allow the buff to spread down over it.
