Another method to dilute the brine is to mix it via a diffuser in a mixing zone. They will maximize iron reduction and chloride removal and will cut down on the electrolysis time. When rinsing is complete, the artifact is removed while the water is hot and wiped with rags.
Some authors have described this as "exploiting micro-niches in the environment". If an object is kept in electrolysis for too short a time, the full potential of electrolysis is not achieved, and the time required to rinse the artifact is significantly increased.
This is similar to the terraced wadis in the southern Negev in Israel see Plate 5. A disadvantage of contour bunds at intervals down the slope is that the crop tends to be uneven, reflecting the soil moisture profile in Figure 5.
Additional wax or wax with graphite added to it as a pigment can be used to cover surface defects in the metal and enhance the appearance of badly corroded objects. It may be sensible to expend only limited effort on building such struc- tures where it is probable that they will be periodically destroyed by flash floods, and an example from Yemen was quoted in Section 4.
A method proposed there by Nilsson consists of forming permanent low ridges about a metre wide which are left to develop this hard crust, while ploughing, cultivating, and planting are restricted to narrow strips of 30 cm Figure 5. If the test is negative, the artifact is ready to be dried and sealed with microcrystalline wax.
Re-treatment is generally prevented only if the artifact is stored or displayed under optimum conditions. This acid introduced additional chlorides to attack the iron.
In many states both State and federal permits are required. In the last two cases, shallow soils become waterlogged because of a limited moisture storage in the profile, and a simple surface drainage system can lead to better opportunities for cropping, or an extended season for grazing. In India, surface drainage can lead to the opportunity for early dry-sowing just before the start of the monsoon where the onset is fairly predictable Krantz A method has been described by Hillel et al Although no membrane exists between the artifact and the electrolyte, the interface between the solid and liquid phases may be considered a membrane.
The crop- ping is usually intermittent on strips or in rows, with the catchment area left fallow. D dam a structure of earth, rock, or concrete designed to form a basin and hold water back to make a pond, lake, or reservoir.
TYPES OF ELECTROLYTIC SETUPS The manner in which artifacts are set up for electrolysis is dependent upon the following factors (Hamilton).
