No – we coat these metals with a special protectant to ensure they will never tarnish when properly cared for.

Yes. We do white color plating such as Silver, Fake Rhodium or Rhodium plating as desired by you. We can also supply our products with bicolor plating. Our Silver plated bangles that match the White Gold color are very popular.

No, the engraving material consists of a plastic base, a micro thin layer of gold or silver and a clear finish on top. The gold or silver has a clear finish to prevent tarnishing and will endure through the years.

Gold plating contacts should be used when your product needs a longer shelf life. Also if the switch will not be actuated for a long period of time after installation we recommend the use of gold plating.

The thickness for gold coatings and platings are often expressed in millionths of an inch, microinches, or microns. The table below will help provide a basic translation between these units of measurements. To translate all this into real world plating thicknesses and their relationship to U.S. Gov. F.T.C. regulations, the following table expressed in microns is provided as a point of reference.

YES, all sterling silver & gold-filled jewelry tarnishes when exposed to acidic skin or air. An ultrasonice cleaner or a non-abrasive polishing cloth (such as Sunshine) will remove tarnish. (Do not put beaded strands in ultrasonic cleaner.)

Yes, "double plating" can be done. But, if you plan to make an order with such process, please confirm with our account executive in advanced. info@scorpion.com.hk it is inferred by their names, "Cloisonne stamped with Hard Enamel" & "Brass Photo-etching with Soft Enamel" do not refer to the same manufacturing processes. Cloisonne stamped with Hard Enamel refers to stamping. The material which is being stamped is Copper. On the other hand, Photo-etching is done only with Brass.

Simply the best looking, most durable gold plating process available. Unlike other's Titanium Gold kits, which are coated with epoxy and may appear grainy as the epoxy wears off, WoodWrite, Ltd. Titanium Gold is a true 24k gold finish over a pure Titanium base which actually shines up as it wears. WoodWrite, Ltd. has found a better method of plating with Titanium which reduces our cost. We also plate with a Titanium alloy which is "EXACTLY" the color of the 24k gold top coat.

Yes, this is called selective plating. Designated areas of the metal object can be plated with yellow, rose and green gold deposits. It also is used for selectively restoring gold plating on metal objects when traditional plating is not suitable due to the fragility of the piece.

Pewter is a prized alloy manufactured from tin, with a small amount of copper and antimony added to give it strength. Considered the world's fourth most precious metal after platinum, gold and silver, its ability to withstand time and its shiny brilliance gives it great value, particularly so when shaped into plates, goblets, figurines, etc. Please see our pewter care page for more information.

The chemicals in some pools and spas may tarnish sterling silver, but because they are sterling, a quick polish will restore their luster. A jewelry cloth for polishing silver can be purchased at your local jewelry store. Also, some people have high acidity levels in their skin, and these rare individuals might have better luck with 14kt gold.

I had played a gold plated mouthpiece for a long time because I liked the feel of the gold on my face and how it warmed easily. But it was important for me to satisfy myself that gold actually WAS better, so when we were in the prototype production phase for the mouthpiece, I had the design team make mouthpieces that were completely silver plated, completely gold plated and also a combination of silver and gold.

No, as a rule the electroplating process does not hide surface imperfections. In fact, due to the diffusive reflection of incidental light rays, pre-existing cosmetic imperfections are even more noticeable on a brightly plated surface! For best results the watch must be polished to the desired level of brightness prior to gold plating.

We can match any color or tint of gold found on vintage watches. Restoring the watch case finish back to it's original factory specifications is what we do best. In addition, unusual gold plated colors such as rose gold, green gold, and even an exotic purple gold finish is available. back to the top

No. It will not turn black. If plating is done properly and the Gold plated item is also stored properly in a moisture free atmosphere then the plating will last for a long time. See in “Jewellery Specifications” - Care of Jewellery.

a rule the thicker the plating, the longer it will last. If you have an item that is subject to high wear or abrasion we recommend a minimum thickness of at least 1.0 microns of electroplated gold. For items such as watches or writing instruments, we have plated thicknesses of up to 7.0 microns of gold. In most cases, this would exceed the original manufacturers specifications for lifetime durability.

For applications where plating thickness is critical we periodically measure plated layers using a process called " x-ray fluorescence". This non-destructive method is very precise for measuring the actual metal deposition on an object after electroplating.

Yes definitely. The perceived gold colour is influenced by brightness of the surface finish. A matte finish will appear paler in colour. A shinier surface will always appear darker in colour. Bead blast or sand blast finishes will appear medium pale in colour when compared to shiny finishes. If colour matching is critical, we can provide (on a limited basis) plated samples that will help you select the correct finish for your item. This article copyright 2002 by Metal Arts Specialties.

Re-plating is renewing the surface of your item with the appropriate metal, silver, gold, pewter, brass, through an electromagnetic process.
