Designed for gold prospectors, panners, miners, collectors, and hobbyists, this complete testing set provides the essential tools needed for traditional acid-based gold testing in one convenient kit.\u003c\/p\u003e\n\u003cp\u003eThe included 10K, 14K, 18K, and 22K gold testing solutions allow you to compare suspected gold against multiple karat levels, while the scratch stone provides a durable surface for creating test streaks. Whether you’re examining nuggets or other suspected gold material recovered while panning, sluicing or prospecting, this kit provides a practical way to perform preliminary gold purity testing.\u003c\/p\u003e\n\u003cp\u003eWith four testing solutions included, this kit offers greater versatility than a single-karat test and makes it easy to keep multiple testing options together in one compact setup. It’s a useful addition to a gold prospecting kit, home testing station, workshop, claim setup, or field gear collection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes: 1 Scratch Stone, 1 bottle of 10K Gold Testing Solution, 1 bottle of 14K Gold Testing Solution, 1 bottle of 18K Gold Testing Solution, and 1 bottle of 22K Gold Testing Solution.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eAlways follow the included instructions and recommended safety precautions when handling acid testing solutions. Acid testing provides a preliminary indication of gold purity and should not be considered a substitute for professional precious-metal analysis when exact composition or purity verification is required.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHOW TO TEST GOLD WITH A SCRATCH STONE \u0026amp; ACID TESTING SOLUTION:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBefore Testing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWear protective gloves and eye protection and work in a well-ventilated area. Gold testing solutions contain corrosive acids and should be handled carefully. Keep testing solutions away from children, skin, eyes, clothing, and surrounding surfaces. Always follow the safety information provided on the product label and Safety Data Sheet.\u003c\/p\u003e\n\u003cp\u003eFor best results, make sure the gold sample and scratch stone are clean and dry before beginning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor kits containing a scratch stone plus 10K, 14K, 18K, and 22K testing solutions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCreate a Test Streak: Firmly rub the suspected gold across the scratch stone several times to produce a clear metal streak.\u003cbr\u003eStart with the 10K Solution: Apply a small drop of 10K testing solution to part of the streak.\u003c\/p\u003e\n\u003cp\u003eCheck the Result: If the streak dissolves, the sample is likely below 10K or may not be gold. If the streak remains, continue testing with the next solution.\u003c\/p\u003e\n\u003cp\u003eMove Up Through the Karats: Create a fresh streak or use a clean section of the stone and repeat the process with the 14K solution, followed by the 18K and 22K solutions as needed.\u003c\/p\u003e\n\u003cp\u003eIdentify the Approximate Range: The highest-karat solution that leaves the streak intact provides an indication of the sample's approximate gold purity.\u003c\/p\u003e\n\u003cp\u003eExample: If the streak remains after applying 14K solution but dissolves when tested with 18K solution, the sample is likely between those two purity levels.\u003c\/p\u003e\n\u003cp\u003eIf the streak remains when tested with the 22K solution, the sample may be approximately 22K gold or higher.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eIMPORTANT TESTING TIPS:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eBegin with the lowest-karat solution and work upward when using a multi-solution kit.\u003cbr\u003eUse a clearly visible metal streak for easier observation.\u003cbr\u003eUse a fresh or thoroughly cleaned section of the stone between different testing solutions.\u003cbr\u003eNever touch the acid bottle or dropper tip directly to the scratch stone or sample.\u003cbr\u003eRecap each testing solution immediately after use.\u003cbr\u003eDo not mix testing solutions together.\u003cbr\u003eAcid testing provides a preliminary indication of gold purity rather than an exact assay.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eA NOTE FOR GOLD PROSPECTORS: \u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eNaturally occurring gold can vary considerably in purity and may contain silver, copper, or other minerals. Gold flakes, nuggets, and specimens may also contain attached rock or mineral material that can affect testing. For these reasons, acid testing is best used as a preliminary field or home identification method rather than a precise measurement of gold content. For exact gold purity, composition, or value, additional professional testing may be required.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"a-list-item\"\u003e\u003cimg height=\"78\" width=\"273\" alt=\"California Proposition 65 warning\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0783\/2056\/6572\/files\/Shopify_Prop65graphic_480x480.jpg?v=1692130729\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"ASR Outdoor","offers":[{"title":"Default Title","offer_id":54058556293420,"sku":"SON-ASRO-GOLDTESTKITWSTONE-5PC-BUN","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/2056\/6572\/files\/ASRO_GOLD_SILVER_ACID_TESTING_SOLUTION_5PC_KIT_MAIN.jpg?v=1790364413","url":"https:\/\/asroutdoor.com\/products\/asr-outdoor-complete-gold-testing-kit-with-acid-testing-solution-scratch-stone-set-5pc","provider":"ASR Outdoor","version":"1.0","type":"link"}
