GUTTAPASSING WITH GLASS TUBE: 1. BASIC POINTS

Here are some tips concerning gutta passing with glass tube.

To avoid gutta problems with painting we have to control the following:

OPTIMAL GUTTA CONSISTENCY for CALM EVEN GUTTA PASSING SPEED;

PRESSURE ON THE TUBE WHILE PASSING THE LINE;

The most important thing is: CORRECT POSITION FOR THE TUBE RELATIVELY TO THE SILK SURFACE.

The SPOUT of the tube should be STRICTLY PERPENDICULARLY to the surface of the silk (Adding the picture below). The  edge of the spout should fit closely and directly to the surface of the silk.

Wrong position of the tube minimize DROPLETT EFFECT causes many problems: not accurate broken line, gutta overflows from tube, etc.

STRICTLY PERPENDICULARLY  position, not to left , not to right!
