New! Bond-Optic Epoxy

  

     Bond-Optic is a water-clear, non-yellowing, two-part epoxy. Bond-Optic was designed especially for lapidary use in stabilizing delicate materials, intarsia work, laminating stone or glass, or filling and strengthening fractures in all types of gemstones. It can also be used on porcelain, glass, metal, wood and much more. Bond-Optic can be colored, or filled to match the material it is being used on.  

     This epoxy was designed with two goals in mind. One, to have a low viscosity in order to be able to fill very fine cracks.  Two, to be absolutely clear and remain clear regardless of age.  This product was tested under high intensity UV light to simulate 20 years of age.  After testing, discoloration was not detectable to the naked eye.  This product was designed to match the quality found in high priced epoxys like Hxtal.

12oz. Bond-Optic Epoxy kit    $60.00

Includes:   
  • 8 oz Epoxy Resin
  • 4 oz Epoxy Hardener
  • 5 1oz graduated mixing cups
Bond-Optic Epoxy is ideal for archeological and restoration work as well.

Instructions: Bond-Optic Epoxy is mixed by weighing 2 parts of resin to 1 part of hardener (2:1). Mixing the epoxy thoroughly is essential. Bond-Optic can be measured using graduated mixing cups or by weight. Altering the mixing ratio will result in the epoxy not reaching full hardness. Additional Graduated measuring cups are available.

Bond-Optic fully cures in approximately 4-7 days at room temperature. Raising the temperature to 85-100 degrees Fahrenheit for 12 hours can cut the full cure time to approximately 1 to 2 days. Raising the temperature of the article being treated to 130-140 degrees Fahrenheit prior to applying Bond-Optic will further reduce cure time. Raising the temperature of mixed Bond-Optic to 120-130 degrees Fahrenheit for 15 to 20 minutes prior to use will decrease curing time to as short as 5 to 8 hours. When heating mixed Bond-Optic, stir the mixture throughout the heating process. Glass rods work well for this. It is best to heat the epoxy slowly and evenly.

Barranca Diamond Blades

BD-297 Standard Notched Rim Diamond Blades
"Barranca's lapidary diamond blades are manufactured ...in the United States. They are made from mechanically notched carbon steel (1045) cores. As the outer circumference of the blade does all the cutting there is minimum side clearance abrasion. This minimizes marks on the cut material, premature segment wear, and core overheating. BD-297 notched rim blades are for use with oil coolants only. "  from the Barranca website -- click link above to see more

The Gem Shop is a dealer of Barranca Diamond Products. All blades below can be special ordered through us. Some sizes are kept in stock and available at all times.
