Resin is a natural secretion of coniferous trees and other organisms. The resin used in jewellery making is an artificial compound called methyl methacrylate, more commonly known as acrylic resin. Resin is clear, but may be coloured using natural pigments or resin dyes. Resin dyes give a translucent colour, while natural pigments create an opaque colour. When colouring resin it's difficult to mix colours, especially natural pigment powders, so get the exact colours you want for your resin items. You obtain optimal results when using colours in the form of powder instead of liquid colours. Use coloured resin to create beads, pendants or earrings.
Prepare the moulds where the resin is poured. Eliminate any dirt, dust or debris.
Pour the resin in a ceramic recipient. Add the natural pigments or resin dyes to the resin and mix to obtain an intense colour. Natural pigments come in the form of powders and you can add several tablespoons of powder to obtain the desired colour. If using dyes, add 1 to 3 drops of resin dyes per 28.4gr. of resin.
Mix the pourable resin with the catalyst included in the resin preparation kit. The catalyst facilitates the hardening of the material.
Pour the resin in the moulds and allow the substance to harden. This typically takes between 30 and 60 minutes, depending on the type and the thickness of the resin.
Remove the resin from the moulds.
Use a wooden stick when mixing the resin. Plastic is less resistant and may also stick to resin. Because resin can be poured in layers, you can create multilayered items, dying each layer with a different colour. Obtain a marbled look by inserting several colours of natural pigments and pebbles in your resin. If using resin dyes, encase various items in the resin including small herbs, coins, shells or coloured rice.
Using liquid colourants can affect the capacity of the resin to cure, so use only small amounts of liquids to colour the resin. Never use oil paints to colour resin. Oil affects the quality of the resin and may not allow it to harden.
