Lamp repair color matching

airbrushed color sample

7 custom mixes prepared

each sample was divided - one half was fired and one half left unfired

Many of the color samples did not achieve a gloss at a temperature below the slumping point of the glass. In subsequent testing flux will be added to the color to attempt to lower the melting point of the enamel.

Samples which matched in reflected light did not look as good in transmitted light.

New pigment options obtained on a recent trip to Germany

Next steps - pigment samples obtained in Germany look promising to match red & brown areas. Best match for the grey is bistre & umber brown mixture but the pigments mature at a temperature well above the slumping point for the glass. I will try adding flux to lower the melting point.
