Sona ki pakki pehchaan karne mein kai tareeke hote hain. Yahaan kuch aam tareeke hain sona ki shuddhata ko test karne ke:
Hallmark Stamp: Asli sona ke jevar mein aksar hallmark stamp hota hai, jisme uske karatage ka indication hota hai. For example, 24K ka matlab hai ki ye shuddh sona hai.
Magnet Test: Sona magnetic nahi hota. Agar jevar ek magnet par chipak jaata hai, toh yeh shayad shuddh sona nahi hoga.
Color Test: Shuddh sona ka rang tez peela hota hai. Dusre dhaatu is rang ko prabhaavit kar sakti hain, isliye yeh tareeka poori tarah se reliable nahi hota.
Density Test: Sona ek ghanee dhaatu hai. Aap kisi cheez ki bhari aur akarshan ko compare karke uski ghanatva ko calculate kar sakte hain. Shuddh sona ka ek vishesh ghanatva hota hai.
Nitric Acid Test: Ye ek adhunik tareeka hai. Nitric acid ko sona ke chhote scratch par lagaya ja sakta hai. Agar koi reaction nahi hota, toh shayad yeh shuddh sona hai.
Professional Appraisal: Ek nischit moolya nikalne ke liye, ek professional johari ya assay office ki sahayata len.
Yeh mahatvapurn hai ki kuch tareeke jevar ko thoda nuksan pahuncha sakte hain, isliye saavdhani se kaam karna chahiye, pehle non-destructive tests ka istemaal karte hue, jaise ki hallmarks check karna ya magnet ka istemaal karna. Agar koi shanka ho, toh ek professional ki salah lena sabse behtar hai.
