One of my favorite documentaries that you can add to your Amazon video library permanently for a bargain. The Price of Gold is brilliant because it's the perfect combination of incredible sports footage, dramatic media coverage, and inside interviews. It was very insightful to see both sides of the story so that Tanya had a chance to save face

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis

Apr 17, 2014 Apr 17, 2014 The Kodak report states that 1,000 square feet of Kodak Gold Film contain four troy ounces of silver, for example, while 1,000 square feet of Kodak Royal Gold 400 film (a “faster” film with a higher ISO rating) contain only 1.1 troy ounces of silver. It takes a lot of rolls of 35mm film to make up 1,000 square feet; however, the report

May 22, 2018 You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off

The plated gold films were produced by first sputtering a 10 nm titanium/150 nm gold film on the test substrates. This sputtered gold layer is the seed layer for the plating of the gold film. The plating bath was 0.1 M potassium gold cyanide bath buffered to pH 7.2 with 0.5 N phosphate buffer. The plating bath temperature was 45 0 C

Jan 31, 2018 Jan 31, 2018 Traditionally, gold is the go-to metal for toning a kallitype, although you can also tone with platinum, palladium, and selenium. Platinum yields an image with more neutral black and white tones

One more factor to consider is processing flexibility. Some films can handle pull or push processing very well, which means developing at shorter or longer times to compensate for over- or underexposure. Ahead, find the five black-and-white 35mm film rolls that we like best
