The vertical bars are also on the light side, but three which come beneath the lug thicken out at the top to give strength. The grid has a very close mesh. It is of course realised that it is not necessary to have a strong grid for the negative. The positive grid is very strong, the horizontal bars being triangular in section, with the apices facing inwards. The vertical bars are triangular where the base of this comes up be the base of the horizontal bar and 4 small projections which form a square, this will give an added protection from falling paste.
