Frit is applied to a warm bead by pressing the bead into the frit. Common methods include using a teaspoon to hold the frit, or rolling the bead on a flat surface, such as a marver, that has been covered in frit.

Generally less is more when is comes to applying frit for two reasons

  1. The frit glass quite often has a different CoE than the base bead and applying more than 5%-10% will result in cracking when being annealed
  2. The frit colours are generally quite vibrant and saturated colurs, and having a smaller amount gives a better effect
