Sun degaussing cleaning method:
Simply place the spar in a position where it can be directly exposed to sunlight, such as a window sill and a terrace; the irradiation time is about 30 minutes to 1 hour.
(1) The spar has a focusing effect when exposed to sunlight. If paper or other combustible items are placed near the spar, there is a danger of fire.
(2) However, if the chromogen of the spar contains copper and iron, it is not suitable for this kind of cleaning method. Since these materials are exposed to sunlight for a long time, they will have an oxidizing effect, thus causing the spar to fade. Chromogens containing copper and iron include crystals such as red or purple.
Moonlight Morning Lighting Method:
On the fifteenth lunar night of the lunar calendar, because the night is a particularly strong moon, it is a good time to dry stone. The stone drying method is very simple. Just put the spar on the terrace or the window and accept the moonlight for one night. Time can be. In addition, you can also put the spar on the terrace and allow it to absorb the essence of the starlight in order to achieve the effect of purifying the spar.
In addition, in addition to the night of the full moon, you can also choose several days before and after the full moon, which is also suitable for this method of drying stone.
If you are exposed to a purple or red spar, remember that you must retrieve the spar before noon of the following day, otherwise the intense sunlight during the day will affect the pigment of the spar and fade it.
