Before you use any resin product, read the manufacturers product instructions and the Material Safety Data Sheet (MSDS). If the MSDS was not included in the packaging, you should be able to download a copy from the manufacturers Web site or at
Most epoxy resins are nontoxic, organic compounds that, once cured (hardened), do not irritate the skin. However, in the liquid state, both the resins and hardeners are skin and eye irritants. Follow these precautions when youre working with epoxy resins:
Invest in a respirator with appropriate filters if you plan to do a lot of work in this medium.
Wear safety glasses and latex or nitrile gloves.
Wet-sand cured resin to minimize resin dust.
Use disposal methods that are recommended by the manufacturer.
Resin:Part 1 of two-part epoxy formula
Hardener:Part 2 of two-part epoxy formula; manufactured in thin or thick formulations
Mixing ratio:The precise proportion of part 1 and part 2 as indicated by the manufacturer
Cure time:The length of time required for the mixed formula to completely harden
Pot life:The amount of time that elapses before the mixed formula begins to thicken
High viscosity:A liquid state that resists flowing; thick liquids
Low viscosity:A liquid state that flows easily; thin liquids
Epoxy resin adhesive:A formulation typically used as a glue; examples include Epoxy 330 and Devcon 5 Minute Epoxy; available at hardware stores
Epoxy resin:A coating or casting formulation; examples include Colores and EnviroTex Lite; available from jewelry suppliers and select craft stores
Characteristics (compared to epoxy resin adhesives):
Pourable epoxy resin formulations from jewelry suppliers and select craft stores.
resin and hardener. The two parts must be mixed in the precise ratio given in the manufacturers instructions. Imprecise measuring and mixing prevents the epoxy resin from curing properly. For small batches, plastic medicine cups work well for measuring the resin and hardener. For larger quantities, its helpful to use a digital scale.
Use a toothpick or wooden craft stick to thoroughly mix the resin and hardener. Stir gently to minimize the formation of air bubbles.
To pop air bubbles, pierce them with a pin. Or, exhale over the surface of the resin; carbon dioxide pops the air bubbles. Another option is to blow warm air over the resin, using a craft heat gun set on low.
When experimenting with color additives, combine them with epoxy adhesives, which cure more quickly and are less expensive than epoxy resin formulations for casting and coating.Weve had success with the following additives:
TIP:Adding colorants to resin can affect the resin-to-hardener ratio, so be sure to consult the manufacturers guidelines before you add pigments.
Mix the epoxy resin.Wearing latex or nitrile gloves and following the resin manufacturers instructions, add the proper proportion of hardener to resin, being sure to account for any modifications in mixing ratios that the manufacturer lists for adding colorants.
Use a wooden craft stick in a figure-8 motion to slowly mix the resin and hardener [PHOTO 1].
Add a colorant.I used a colorant that I purchased from the resin manufacturer.
Use a toothpick to add just a dot of color and mix thoroughly.
TIP:A tiny amount of pigment goes a long way. Add pigment sparingly, just a little at a time, until you achieve your desired translucent or opaque color.
Pour the resin into the bezel.Avoid pouring resin in the openings of the tube components. Hold the pouring cup stationary while you pour resin in one area of the bezel [PHOTO 2]; this minimizes the creation of air bubbles. Pour until the resin domes slightly and is even with the top edge of the bezel wire. Repeat to fill the other open area of the bezel.
Remove air bubbles.Use a pin to pierce any air bubbles that formed from pouring the resin.
Cover and cure the resin.Place a box over the assembly, and allow the resin to air-cure according to the manufacturers instructions.
TIP:When pouring resin, leave a layer of resin in the pouring cup. You can then use this leftover resin to check if the resin is completely cured, instead of making test pokes into your jewelry piece.
