cow-dung ash powder, it is possible to get precipitation of it, even by dissolving comparatively smaller quantity.
Although the fineness of proper ash powder does not vary widely. but People are now also using flyash, which is easily available from industries. It is difficult to tell the proper quantity and fineness of flyash powder or lime of lime solution in practical terms. Modern gadgets may help to quantify these parameters for them. But then it has also to be simple and practically viable for a lay shrãvaka to adhere to it. 6. MILK:
It is a colloid and falls under an agreeable juice category. Its limit less quantity can be dissolved in water. It is available in body form, instead of in molecular form. It makes homogeneous solution with the body of water. If its container is rub washed with water, it can break the water body structure to make the wash water non-living. Even its minute quantity can change the colour of water. There is no precipitation in milk solution. As such from practical view point, it is considered to be unsuitable for making dhovana. Sãdhakas do not take chance to remain under the state of suspicion. 7. Conclusion: i) Highly soluble materials or those materials, which are capable of
changing the colour of water even with its minute quantity, are considered to be unsuitable for suspicion-free dhovana making. One of its reasons is that no practically simple and fool-roof measurement can be assigned for a just “sufficient quantity" of these materials. If the required quantity is small, it cannot be seen by way of precipitant. The precipitant indicator is the most practical method to keep the Sãdhakas doubtfree about the validity of proper dhovana making process.
The astringent materials are not easily soluble, but can discolor the water even with the use of its minute quantity. The exact quantity used remains always uncertain. Hence they are declared
unsuitable for efficient (prasuk) dhovana. iii) A few Acharyas have tried to specify how much Lime or Trifala
powder should be used in 10 liters of water. It has to be vigorously stirred for a minute. It becomes useable dhovana after 24 minutes
