Good morning from (windy today) New Zealand, I dropped my second batch of gold last night and it settled overnight, I've now come to the washing part and have a couple of questions
The tutorial includes the following steps:
5.Add just enough water to cover the gold powder and boil for 5 minutes (Removes undissolved and water soluble salts)
6.Let settle and pour or siphon off the water into the stock pot.
7.Repeat three times.
8.Add just enough muriatic acid to cover the gold powder.
9.Boil until the acid is no longer discolored by the process and pour or siphon off into the stock pot after testing with stannous. If gold is present keep in separate beaker to precipitate later.
10.Repeat the water rinse as above.
Question: For step 6, do you want to pour off the water while it is still very hot ? If you have to wait another few hours for any suspended gold to settle, won't the salts you dissolved with the hot water crystallize out again ?
