In the market, this trowel is available. However, as per the needs of the work, trowel of different sizes are made.
13. Soil Carrying Wheelbarrow, Baskets and Trays : During the archaeological excavation work, Soil Carrying Wheelbarrow, Bamboo Baskets and Iron Trays are used to carry the earth (soil) from the trench to the other place. These tools can also be used in other works related to the excavation. In the market, these tools of different sizes and shapes are available. However, as per the needs of the work, these tools are made.
14. Soil Color Chart : One of the essential ingredients of archaeological excavation is Soil Color Chart. During the excavation, this color chart is used to determine the soil color of the uncovered contexts or strata in the trench. The soil color determined from the uncovered contexts or strata is used to analysis data or stratify different strata during the report preparation on archaeological excavation.
15. Scale : Scale is an essential tool of the archaeological excavation. Using scales of various shapes during the excavation, the movable and movable objects explored in the excavation trench are measured and drawn.
16. Twine : During the archaeological excavation, the thick-thin twine is used as an essential element to bind in different types of bindings. The twine of the high quality and different brands is available in the current market.
17. Knife : During archaeological excavation, knives of different types as an essential element are used for cutting. Knives of different brands and sizes are available in the current market.
