The reactive finish is a single event heat reactive finish. As the images show, once a heat source is applied the darker outer colour gives way to the brighter colours hiding underneath. Not only does this change colour, patterns can also emerge with the introduction of heat. Click on the images below to see the before, during and after effects of this truly remarkable finish. Left to cool, the substrate returns to its original colour or introduce a cold source and you get an instantaneous cooling effect as the washbasins show with great effect. As this effect can be applied to almost any substrate all that is required is heat and your imagination.
