Hey guys
We are a small independent watch brand ftom Brazil and after our first release, we are trying to give some depth to our brand.
We are planing a new collection with self made enamel dials and we are in the middle of the process of learning
We are having a lot of holes and bubbles in our experiments even when changing the apply tecnique, cooper cleaning method and time of firing and temperature.
Enamling is something ive yet to try but dying to.
There can be a few reasons pits are forming. The enamel should be cleaned. Of ten the enamel from the jar may have contaminates from the creation of the fret. I place some enamel in a shallow tray and put in some water. The dirt or cloudy dust comes to the surface - this gets drained off (great to add to the counter enamel which doesn’t seem to matter as much) the piece may also be a bit damp before firing. The klyrfire can heat up and pull away from your copper. Of the pits are very noticeable, sand the surface , clean with a glass brush and retire. It may help
