335. Washing

Washing. The plates, after fixing, should be removed from the rack for final washing. The washing is preferably done in a regular washing tank, or it may be done in trays. When removing the plates from the rack, turn the rack on its side and withdraw the plates. See Illustration No. 43. If plates were inserted with glass sides together and two plates in one groove, they must be separated by sliding one plate past the other, lengthwise. See Illustration No. 44.

336. In Illustrations No. 45 and No. 46 are presented two styles of very simply constructed developing tanks, the Ingento Automatic Developing Tanks, fitted with light-tight metal covers. While the loading of these tanks must be done in the dark, yet the developing can be carried on in daylight. The tanks are made for all sizes of plates from 3 1/4 x 4 1/4 to 8 x 10. The Style "A" tank is made of brass, nickle-plated, and fitted with a removable rack, and can be used for developing, fixing and washing. When the plates are developed

the developer can be poured off and sufficient hypo solution poured into the tank to cover the negatives. After the plates are fixed the hypo solution can be poured into a jar or vessel and saved for the next batch of plates, and the tank can then be used as a washing box, by allowing the water from the tap to enter through the funnel. In this way the hypo will be thoroughly eliminated from the negatives and tank simultaneously.

337. Style "B" tank is more cheaply constructed and Is made of zinc, with side walls fitted with long grooves, to receive the plates, and has a patent lifting bottom, by means of which the plates, after developing, may be raised to the top of the tank and removed to the fixing bath without dip-ping the fingers into the solution. This style tank can be used for developing and washing, but it is not recommended for fixing, as zinc will gradually disintegrate under the action of hypo solution; therefore, where zinc tanks are used an extra fixing tank should be employed.
