When the specimens look clean, remove them with rubber gloves or tongs and then run them under water from a hose. Take 30 seconds to 1 minute to flush any acids from each sample. Prepare a solution of baking soda and water, place the stones in this overnight to neutralize any leftover acids in cracks or seams.

I know many dyers who use either sodium hydrosulfite ("hydro") or thiourea dioxide ("thiox") to reduce their vats. These chemicals work efficiently and predictably and can now understand why a dyer …

Sodium dithionite is stable when dry, but aqueous solutions deteriorate due to the following reaction: 2 S 2 O 42− + H 2 O → S 2 O 32− + 2 HSO 3−. Anhydrous sodium dithionite decomposes to sodium sulfate and sulfur dioxide above 90 °C in air. In absence of air, it decomposes quickly if heated above 150 °C to sodium sulfite, sodium ...

Cleaning with sodium hydrosulfite. Below is a typical resin cleaning procedure using sodium hydrosulfite. Most resin manufacturers recommend a dose rate of sodium hydrosulfite of 1.25 pounds per cubic foot of resin. Backwash the resin. Regenerate the resin with brine. Slow rinse the resin to a slight salty taste.

Sodium hydrosulfite may be employed as a reducing agent for the reduction of graphite oxide in a study. Sodium hydrosulfite has been used as a fluorescent quenching agent in the encapsulation of polynucleotides via production of asymmetric nanoparticles. It has also be used in the form of buffer for the elution of probe labelled proteins involved in the …

The first indigo vats that I made in the 1970's were reduced using sodium hydrosulfite. It was the only way I then knew to reduce the indigo. A few years later I began using thiourea dioxide as the reducing agent. I was never comfortable with these vats and, as a result, I never did much indigo dyeing. The vats smelled bad and I felt that I ...
