Celtic Triquetra Knot Brooch, Trinity Knot Pin
Like all Celtic knots the triquetra is constructed of one continuous line interweaving around itself symbolising no beginning or end, an eternal spiritual life. The Celts favoured the idea that everything important in the world came in threes; three stages of life, three elements, three domains; earth, sea and sky, past, present and future.
Each item begins as a piece of sheet metal, copper, bronze, brass or nickel. After a pattern is transferred to the metal, the piece is etched in a salt-water solution. Each piece is hand cut, sanded, and polished. A patina may be applied or it may be hand painted with dye oxide. A clear polymer coating is applied and a pin attached to the back with adhesive.
