One more thing you might want to do. Read Hoke. Read it again. Read it a third time, writing down questions you have. Perform the acquaintance experiments she describes. By this time you should be familiar with both terminology, which can seem like learning a new language, and basic procedures.
Study the Forum sections on safety and dealing with waste. Things were different seventy years ago when Hoke wrote her book for jewelers. Safety and waste treatment procedures have improved dramatically.
With a little humility and a lot of effort on your part, forum members may be able to help you fix your mess. Best advice is to present your plan here, in detail, and discuss it with others.
Time for more coffee.
Edit: 500 ml of problem solution is small, so take it in small steps.
