Charbonnel liquid transparent ground 75ml

Producer: Charbonnel

The varnish is applied cold with a brush, it dries relatively slowly, and the clarity of the varnish allows you to clearly see the design. Capacity 75ml.
After the plate is left in the acid for the required time, the plate is removed from the acid bath solution and the medium is removed with a suitable diluent. The amount of time the tile is left in the acid depends on the acid strength (measured with an acetometer), room temperature, and the depth at which you want to hit. The etching is then done and you only need to apply the final cuts. A retouching primer can be applied to the board, which can then be retouched as required according to the lines of the previous etching.
