Use only with proper ventilation, chemical-resistant gloves, eye protection, protective clothing, and appropriate lab-safe containers. This kit is intended for adults with an understanding of chemical safety.\u003c\/p\u003e\n\u003cp\u003eNever mix chemicals casually. Never work indoors without active chemical ventilation. Never inhale fumes. Keep all chemicals away from children, pets, flames, food, and household surfaces.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch1\u003eWhat Each Item Is Used For\u003c\/h1\u003e\n\u003ch2\u003eNitric Acid 69.8%\u003c\/h2\u003e\n\u003cp\u003eNitric acid is used as part of the dissolution stage when properly combined in a controlled refining process. It helps create a reactive acid system capable of dissolving gold-bearing material.\u003c\/p\u003e\n\u003cp\u003eUse only in proper chemical glassware and only with adequate ventilation. Nitric acid can produce dangerous fumes and can react violently with incompatible materials.\u003c\/p\u003e\n\u003ch2\u003eHydrochloric Acid 31%\u003c\/h2\u003e\n\u003cp\u003eHydrochloric acid is used with nitric acid during the dissolution stage. It provides the chloride component needed in traditional aqua regia chemistry.\u003c\/p\u003e\n\u003cp\u003eHydrochloric acid is corrosive and produces strong fumes. Keep the container closed when not in use.\u003c\/p\u003e\n\u003ch2\u003eBorosilicate Beaker\u003c\/h2\u003e\n\u003cp\u003eThe borosilicate beaker is used as the main reaction vessel for acid-resistant laboratory work. Do not use household glass, metal bowls, plastic food containers, or aluminum containers.\u003c\/p\u003e\n\u003cp\u003eInspect the beaker before each use. Do not use if cracked, chipped, or damaged.\u003c\/p\u003e\n\u003ch2\u003eMagnetic Stirrer Hot Plate\u003c\/h2\u003e\n\u003cp\u003eThe magnetic stirrer provides controlled mixing during laboratory processing. The hot plate function should only be used when appropriate for the process being performed and with extreme caution.\u003c\/p\u003e\n\u003cp\u003eDo not overheat acid mixtures. Do not leave the stirrer unattended.\u003c\/p\u003e\n\u003ch2\u003ePTFE Magnetic Stir Bar\u003c\/h2\u003e\n\u003cp\u003eThe stir bar sits inside the beaker and rotates when the magnetic stirrer is turned on. It helps keep the solution moving evenly.\u003c\/p\u003e\n\u003cp\u003eRinse and clean after use. Do not use damaged stir bars.\u003c\/p\u003e\n\u003ch2\u003eStannous Chloride Gold Test Solution\u003c\/h2\u003e\n\u003cp\u003eStannous chloride is used to test whether dissolved gold is present in solution. It is a confirmation tool, not a recovery chemical.\u003c\/p\u003e\n\u003cp\u003eA positive test indicates gold may be present in solution. A negative test may mean the gold is not dissolved, is too dilute, or the test solution is no longer fresh.\u003c\/p\u003e\n\u003ch2\u003eVacuum Filter Flask\u003c\/h2\u003e\n\u003cp\u003eThe vacuum flask is used with the Buchner funnel to speed filtration and separate insoluble solids from liquid solution.\u003c\/p\u003e\n\u003cp\u003eUse only with compatible vacuum equipment. Do not use cracked glassware. Do not apply excessive vacuum pressure.\u003c\/p\u003e\n\u003ch2\u003eBuchner Funnel\u003c\/h2\u003e\n\u003cp\u003eThe Buchner funnel holds the filter paper during vacuum filtration. It allows solids to stay on the paper while filtered liquid passes into the flask.\u003c\/p\u003e\n\u003cp\u003eUse with correctly sized filter paper. Make sure the paper is seated properly before filtration.\u003c\/p\u003e\n\u003ch2\u003eFilter Papers\u003c\/h2\u003e\n\u003cp\u003eFilter papers are used to capture undissolved solids, debris, and recovered powder depending on the stage of the process.\u003c\/p\u003e\n\u003cp\u003eUse fresh paper when switching stages. Do not reuse contaminated filter paper.\u003c\/p\u003e\n\u003ch2\u003eUrea\u003c\/h2\u003e\n\u003cp\u003eUrea may be used in some refining workflows to help reduce excess nitric activity before precipitation. It should be added only according to a validated refining procedure.\u003c\/p\u003e\n\u003cp\u003eOveruse or misuse can interfere with results, so it should not be treated as a general neutralizer.\u003c\/p\u003e\n\u003ch2\u003eSulfamic Acid\u003c\/h2\u003e\n\u003cp\u003eSulfamic acid is commonly used in refining workflows as a more controlled de-nox option than urea. It may help reduce excess nitric activity before gold recovery.\u003c\/p\u003e\n\u003cp\u003eIt should be used only in appropriate conditions and with proper ventilation.\u003c\/p\u003e\n\u003ch2\u003eSodium Metabisulfite\u003c\/h2\u003e\n\u003cp\u003eSodium metabisulfite is the gold precipitant included in the kit. It is used after gold has been dissolved, filtered, and properly prepared for recovery.\u003c\/p\u003e\n\u003cp\u003eWhen used correctly, it causes dissolved gold to drop out of solution as brown powder.\u003c\/p\u003e\n\u003ch2\u003eCeramic Drying Dish\u003c\/h2\u003e\n\u003cp\u003eThe ceramic dish is used to hold recovered wet gold powder during drying.\u003c\/p\u003e\n\u003cp\u003eUse low, controlled drying conditions. Do not use food dishes or cookware.\u003c\/p\u003e\n\u003ch2\u003eBorax Flux\u003c\/h2\u003e\n\u003cp\u003eBorax flux is used during melting to help protect and clean the melt. It is not used during the acid dissolution stage.\u003c\/p\u003e\n\u003cp\u003eMelting requires separate proper equipment, including a torch or furnace, crucible, heat-resistant surface, and protective gear.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch1\u003eGeneral Process Overview\u003c\/h1\u003e\n\u003ch2\u003eStage 1: Prepare Material\u003c\/h2\u003e\n\u003cp\u003eOnly use appropriate gold-bearing material. Remove stones, dirt, non-metal pieces, and unnecessary contaminants before processing.\u003c\/p\u003e\n\u003cp\u003eCleaner starting material generally produces cleaner recovered gold.\u003c\/p\u003e\n\u003ch2\u003eStage 2: Dissolution\u003c\/h2\u003e\n\u003cp\u003eThe nitric acid and hydrochloric acid are used during the dissolution stage in proper laboratory glassware.\u003c\/p\u003e\n\u003cp\u003eThis stage produces strong fumes and must only be done with proper chemical ventilation and safety equipment.\u003c\/p\u003e\n\u003ch2\u003eStage 3: Testing\u003c\/h2\u003e\n\u003cp\u003eThe stannous chloride solution is used to confirm whether dissolved gold is present before continuing.\u003c\/p\u003e\n\u003cp\u003eTesting helps avoid wasting recovery chemicals or proceeding before dissolution is complete.\u003c\/p\u003e\n\u003ch2\u003eStage 4: Filtration\u003c\/h2\u003e\n\u003cp\u003eThe Buchner funnel, filter paper, vacuum flask, and vacuum source are used to remove insoluble material from the solution.\u003c\/p\u003e\n\u003cp\u003eClearer filtered solution generally improves the recovery stage.\u003c\/p\u003e\n\u003ch2\u003eStage 5: Nitric Control\u003c\/h2\u003e\n\u003cp\u003eUrea or sulfamic acid may be used, depending on the chosen workflow, to help reduce excess nitric activity before precipitation.\u003c\/p\u003e\n\u003cp\u003eThis stage is important because excess nitric can interfere with gold recovery.\u003c\/p\u003e\n\u003ch2\u003eStage 6: Gold Recovery\u003c\/h2\u003e\n\u003cp\u003eSodium metabisulfite is used to precipitate dissolved gold from the filtered solution.\u003c\/p\u003e\n\u003cp\u003eGold typically appears as brown powder after recovery.\u003c\/p\u003e\n\u003ch2\u003eStage 7: Collecting Powder\u003c\/h2\u003e\n\u003cp\u003eFilter paper and the filtration setup are used again to collect the recovered powder.\u003c\/p\u003e\n\u003cp\u003eThe powder should be rinsed and handled carefully to avoid loss.\u003c\/p\u003e\n\u003ch2\u003eStage 8: Drying\u003c\/h2\u003e\n\u003cp\u003eThe recovered powder is transferred to the ceramic dish and dried completely before melting.\u003c\/p\u003e\n\u003cp\u003eWet powder should not be placed directly into a hot melt.\u003c\/p\u003e\n\u003ch2\u003eStage 9: Melting Preparation\u003c\/h2\u003e\n\u003cp\u003eOnce dry, the recovered gold powder may be prepared for melting using borax flux.\u003c\/p\u003e\n\u003cp\u003eMelting equipment is sold separately.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch1\u003eImportant Notes\u003c\/h1\u003e\n\u003cp\u003eThis kit does not include melting equipment, crucibles, molds, respirators, gloves, goggles, or neutralizing supplies.\u003c\/p\u003e\n\u003cp\u003eUsers are responsible for understanding chemical safety, local laws, waste disposal requirements, and proper refining procedures before use.\u003c\/p\u003e\n\u003chr data-start=\"1780\" data-end=\"1783\"\u003e\n\u003ch2 data-start=\"1785\" data-end=\"1810\"\u003eDesigned For Beginners\u003c\/h2\u003e\n\u003cp data-start=\"1812\" data-end=\"1881\"\u003eThis system removes the confusion that most first-time refiners face.
