A year ago, we were making laminated copper laps. We were using 1/8″ copper. The problem with this was that people would see Printed Circuit Board film versions at very low prices, and did not distinguish the difference. We have made solid copper laps in the past, sometimes as specialties, and there is always a low-level demand for them. Copper has been used for many years (Centuries?), for polishing the harder stones, for prepolishing with 3K, or for cutting, depending on what they have been charged with. Recent requests from stocking dealers have convinced us to stock them again. Copper is a good old reliable standard. Properly cared for, they can last a lifetime.
The Alpha Lap is especially useful with a water mist or drip on stones with surface reaching flaws or voids that could otherwise become packed with polishing agents, and of course, for emeralds, it is oil-fee.
Adamas developed the Alpha? lap to polish all gem materials that will polish with Aluminum Oxide. The Alpha Lap is manufactured by Gearloose Lapidary LLC. At low to moderate lap speeds, you can polish on this lap with just a water drip on the surface due its oxide/polymer composition. Works well on gemstones between 7 and 8 Mohs hardness, such as Beryls, Garnets, Tourmaline, and many others. Unlike previous Aluminum Oxide/polymer polishing laps, this one really works. The Alpha Lap is especially useful with a water mist or drip in stones with surface reaching flaws or voids that could otherwise become packed with polishing agents, and of course, for emeralds, it is oil-fee. For general cutting it may be used with any high quality accurately graded slurry for faster speeds and the prevention of long-term glazing.
An outer band of the TIN PLUS alloy furnishes a fast prepolish. Usually charged with 3K Diamond. Tin Plus is gentler than the harder alloys and charges more readily. The inner polishing zone is the new boosted version of the Creamway Zirconia composite. From the good prepolish of the 3K/Tin Plus the silica and silicate gem facets are polished in seconds to a perfect chemomechanical surface.
TIN PLUS - Polishing & pre-polishing lap
A tin alloy version of the popular Zinc Plus prepolishing lap. An affordable Tin-based laminated lap, the alloy is halfway between Pure Tin and BATT in Brinell Hardness. Gentler in use than harder alloys and charging more readily, it will give excellent results with stones from hardness 4 to 8, but will still handle sapphire.
These Lyra sharpeners are designed originally for graphite crayons. They work well with the new waterproof-packaged BATTSTIKs?
