## 1. Casing Specifications
There are three standard levels of casing for sacred items:
1. **Stainless/Plastic:** Standard protection; not airtight.
2. **Micron/Gold Plated:** Aesthetic value; water-resistant.
3. **Waterproof Acrylic (Chub-Nam-Man):** The gold standard. The amulet is vacuum-sealed in acrylic to prevent any air or sweat contact.
## 2. The Oxidation Rule
**Copper (Nuer Thong Daeng)** and **Silver** amulets will turn black or green if exposed to sweat. Once oxidation occurs, the "skin" (*Piew*) of the amulet is permanently altered, reducing its collector value.
## 3. Ritual Cleaning Protocol
If an amulet is not cased and becomes dusty:
* **Step 1:** Use a very soft, dry camel-hair brush to whisk away debris.
* **Step 2:** Never use water or oils on powder or clay amulets.
* **Step 3:** For metal amulets, a tiny drop of pure sandalwood oil on a cotton bud can be used to prevent rust, but only if the item is not already oxidized.
Sacred items are porous and sensitive to environmental shifts. Proper "casing" (encapsulation) prevents oxidation and moisture damage, while ritual "cleansing" maintains the item's spiritual integrity.
Researcher Note:
Always store your amulets in a place higher than your waist. In Thai tradition, keeping sacred items in low places (like pockets or on the floor) is considered disrespectful to the energy of the item.
