Serious things could be extremely simple
Rich, complex structures of small salt crystals help purify and salinize the air.
“The saline garden” is a rich crystal structure which can improve air hygiene in a confined space by retaining aerosols, dust and odors. And - most importantly – it produces salt microcrystals, which, when taken by the air currents and breathed in, lead to consistent beneficial effects on the respiratory system.
It is what happens in salt mines and the same principle is used in Salin devices, INSALIN individual inhalers, but also in SaltMed medical inhalers devices used throughout the world for their complex beneficial action on the respiratory system with applications in case of asthma, bronchitis, rhinitis, respiratory insufficiency, respiratory viruses etc.
I describe here the primary process of obtaining very rich structures of salt crystals, a process that can be easily reproduced and used. These structures have high efficiency in the general hygiene of the air and, in particular, they have beneficial effects on the respiratory system of the users. Usually, people with different respiratory problems feel better after few days of use.
The idea is to bring a very concentrated solution of salt on a porous surface that is exposed to air. The solution will infiltrate, diffuse through the porous surface and evaporate gradually producing myriad salt crystals on the surface. In time, if the area is moistened with salt solution periodically, the crystallized structure will develop up to thicknesses of several millimeters to centimeters, in crystallized forms similar to corals.
During this process of crystallization, the small air currents in the room will pick up salt microcrystals from the surface of the structure, “salting” (salinating) the air. The degree of salinization of the air in itself is small (although measurable with fine laboratory methods), but sufficient to induce the effects on the respiratory system. When leaving in this space, people will be exposed for long periods to this salty air. The respiratory system will work better, people with different respiratory problems will feel better and everybody will have raised their resistance to respiratory viruses.
- 1kg food salt of any kind;
- a base support plate, which could be a wide plate with a slightly raised edge or a smaller plastic tray;
- a bigger tray in which the plate or tray describe above may be placed;
- paper towels / roll of kitchen towels;
- a spoon;
- a pair of scissors.
2. How to do it
In this example I use a 20 cm wide paper towel roll from which you cut squares of 20 cm.
Put the paper towels over each other in about 8-10 layers. Bend on one diagonal the pile of paper towel obtained and repeat for the other diagonal (see illustration below)
2. 8-10 paper towels
3. bend on the diagonals
4.bend on half
5. pile of bent towels
6. salt on the plate
Put 200-300g salt and after add 200-300 ml of water obtaining a level of 5-7mm saline solution on the plate.
Unfold the 4 wings to obtaining a structure that is self-sustaining (as illustrated below -8).
7. add water on the salt
8. make a pyramid
9. pyramid on the plate
Put the paper pyramid on the plate and wait few moment as salty water start to infiltrate the base of the pyramid.
The salty water will infiltrate in the paper structure from bottom to top and will moiture the whole piyamid. After 20-30 minute add water to maintein the level at 5-7mm. The cristals will start to grow very fast and a little salt garden will arise.
3. MaintenanceDuring the growth of the crystals, you must add, from time to time, water or salt on the base support plate:
- Water- water it like a plant. At each 4-5 days, add water to have the saline solution at a height of 5-7mm. After it became dry, water it again.
- Salt, if there are no salt crystals left in the saline solution. Depending on the size of the garden, it will require between 0,5-1-1,5 kg.
Even after the first day, if you look closely, you will see small crystals of salt on the surface of the pyramid, both on the outside and inside. After few days the crystals will be more visible, and the quality of the air will be improved. In 10 to 14 days, depending the environmental temperature, we could obtain a very rich structure and an excellent salinization of the air. It is important to always keep into the base support recipient the support the clear solution and some quantity of undissolved salt.
In the pictures above is presented a „Saline garden” after first 2-3 days. You can see many small crystals of salt already formed on the surface of the structure and on the base support plate. When the thickness of the crystal layer reaches 5-10 mm you can stop adding salt (you will keep adding water though). For the saline gardens of 10-12 cm high, the solution in the base support plate will maintain the structure permanently moist to ensure that crystals will grow and change permanently. For tallest saline gardens, you will need to moisten the top of the pyramid from time to time.
All this time you can watch how crystals grow in your saline garden and, more importantly, you will feel the change in the air quality through salinization.
A garden needs care to be beautiful and useful. Saline gardens will do their job to salinize the air without asking for a lot of special attention. However, you will have to look after them from time to time. They are constantly changing; the salt will crystalize on the base support recipient and will eventually crawl out of it.
In order to optimize the effect, saline gardens are recommended in every room of your house: bedrooms, living rooms, could all accommodate one or two saline gardens.
Talk about your saline garden, share with others, tell the story about how it looks and what you feel regarding the air around it, so that more people learn about it and use them. It costs little to nothing, but the effect it produces can make a difference for our health and the health of others.
It is a moment when we isolate ourselves to realize how connected we are and how much what we do matters for the others.
