    Default What are pigments

    G,day Guys and Ladies
    I have a question I have only recently started to cast resin blanks ( Well I havnt cast anything yet I still working things out) but I have perlex powders to colour my resins when I do cast something, but reading some of the threads on the forum I notice the mention of pigments at time to time. Not knowing a lot as yet Are pigments something different to Pearlex powders? I thought pigments just ment the colore of the product you where using.
    Hoping for a replie to my question
    Steve

    Pearlex powders are very fine glittery powder actually made by make-up companies (eg eye shadow). They mix with any resin and continue to move in the resin until it sets, producing a swirling pattern, giving highlights and shadows depending on the concentration of the powder in the resin. To little powder will result in a translucent resin.

    Pigments are thick gooey colours that give a solid colour in the resin (ie not translucent). You must use the correct pigment type for the resin you are using.

    Dyes (just a matter of time before you ask) are translucent pigments. Like solid pigments you must use the correct dye type for the resin you are using. The darkness/% translucence depends on how much you use.

    You can add pigments and dyes to Pearlex powders to produce extra colours and % translucence.

    There are also a heap of other powders you can use. Glow/glitter/metallic and many more. You do have to be careful with these as they often start to float or sink in the resin as soon as you stop stirring.

    The other thing to be aware of is that all additives can effect the setting times for the resins. Too much will often slow the setting times, sometimes actually stopping it, other times it can speed things up to the point of 10 second set-up times. All learnt from experiments and experience.

    Good luck

    I've used the earth tone ones to colour epoxy and there must be a source in Australia, but the place I got mine from (Stimmo's in Rozelle) closed about 15 years ago.

    The simplest explanation is the pigments are super small colourful rocks. All coloured paints are made up of a binder (the glue that holds the pigments together) and pigments. Titanium dioxide is the most common white pigment, with a wide range of colours available from other pigments.
    The pastes we typically use are pigments ground up super fine and dispersed in a liquid that is compatible with the paint/resin into which it is added.

    Pearlescent pigments are typically made from mica and flake pigments are typically aluminium.

    Hope this helps,
    Peter
