2300 Opalescent Green


Opalescent enamels are semi transparent, usually getting more transparent the higher they are fired. They need a special firing to acheive opalescence. Remember opalescence cannot be acheived over another layer of enamel. The copper oxides that are absorbed in a 'next-to-copper' firing are essential for developing the opal effect.

If opal enamels are fired over other enamels they will never be truly opalescent - but they will be partly clear and can be very effective in cloionne for creating a semi-transparent alabaster effect with a great deal of depth.

The procedure I recommend for acheiving opalescence is to fire once high to acheive transparency, and then low for 3 to 4 minutes to develop the effect.

Opal colours are soft and ACID SENSITIVE
