Basic Resin Techniques Will Assist
In Making Resin Jewelry
Basic resin techniques should be used when making resin jewelry,the most critical factor for success is accurate measuring and mixing of the resin and hardener.
Wrong measurement may result in tacky or flexible resin after curing.
Use graduated mixing cups,fill carefully according to the stated amounts. Most resins require one part resin to one part hardener.
You can also use digital scales for accurate measurements.
Always mix the correct ratios of resin and hardener.
There are exceptions to this and you should always check the resin techniques as given by the manufacturer. Some resins need drops of hardener rather than an equal amount.
Work in a clean dust free area and at room temperature. Use a stir stick to mix the resin until it is properly mixed.
Always wear your safety equipment when working with resin.
Follow the mixing instructions, the longer you mix the more the resin will thicken and reduce your working time. This is known as pot life, the amount of time you have to work.
Air Bubbles
It is quite common after mixing your resin and pouring it into a mold air bubbles will be present. Unless you want to leave them in your design they should be removed before the resin cures.
They can be removed with a vacuum chamber, probably impractical for home use, or with a heat gun purchased from a craft or hobby store.
Hold the gun vertically, not at an angle, a few inches above the mold and move it across the mold. Do not hold in one spot for long as the heat can damage the mold or any inclusions in your resin jewelry piece.
If you don’t have a heat gun, gently and carefully blowing on the resin can also remove bubbles.
You will also find bubbles when you are filling small pendant frames or other types of resin fashion jewelry, gently apply the above resin techniques.
Curing
Curing times will vary and can be affected by the type, amount, and brand of resin used as well as temperature and humidity
Resin is fully cured when it is hard and no longer tacky nor flexible.
If resin is not set it will show finger marks if you touch it.
I like to put some unused resin onto a piece of scrap acrylic or plastic and touch this to test if it has cured.
Resin cures best at room temperature.
You can reduce the curing time by increasing the temperature.This can be simply done by placing the resin under a low-watt light bulb or in a light box.
Do not cure too quickly or the piece may fracture or warp.
It is important during curing that the resin is kept in a warm, dust free room.
