how to make flux for gold refining. the flux is added to a crucible with the gold that is then melted in a furnace. you can make flux for gold refining by first obtaining all of the ingredients and then mixing them together in the proper portions. measure and weigh 5 oz. of anhydrous borax using the digital scale. measure and weigh 40 oz.
video of the day. a crucible used for melting gold looks similar to a bowl with no lid or top on it. add a few pinches of sodium carbonate and a few pinches of borax for your flux. turn on the torch and very slowly touch it to the gold itself in the crucible. keep torching until all gold melts down to molten form.
set the crucible directly on the charcoal. load more charcoal around the crucible. turn the hair dryer on low to force air into the chamber below the charcoal. if the temperature fails to get high enough to melt your ore, turn the hair dryer up to high. be very careful not to get the charcoal so hot that it causes the ore to liquefy and then bubble.
put the gold in the bottom of a cast-iron pot. cast iron is good to use because it's readily available and has a melting temperature almost 900 degrees higher than gold. turn the propane torch on and set it to a medium flame. hold the end of the flame directly against the gold. as the gold heats up, it will turn to a liquid state and form a puddle.

salt dough was commonly used in the crafting world many years before modern polymer clay. hard objects can be created from the simple combination of salt, flour and water placed in a hot oven. fake food can be created from this easy dough, and is a great craft to do with children as it is nontoxic and easy to clean.
