It was discovered long ago that a few drops of Mrs. Stewart's Bluing in the rinse water when cleaning crystal chandeliers extends the sparkle, and does the same for mirrors and windows. It is believed that dust particles are repelled by the bluing and the cleaning lasts much longer. In addition, light may reflect more effectively off of the bluing particles deposited on the glass surfaces. How can we disagree? Here is an article with more information. PDF
The fact that Mrs. Stewart's Bluing mixes readily in any water-based solution makes it ideal to color the casting material used in podiatry laboratories. By adding a blue color to certain layers of plaster used in casting, it is more easily determined where to add more plaster and where it is necessary to cut away. It is similarly used in sculpture and pottery work.
Many loyal customers attest that Mrs Stewart's Bluing works with septic tanks. The ingredients in MSB should not disable the other chemicals you use to keep your septic tank healthy. Many say it is the only whitener on the market that they are able to use.
We have asked the Septic Tank "Seal of Approval" people to test our product to be endorsed by them. They have not complied due to our small size.
A woman called several years ago looking for Mrs. Stewart's Bluing for use in her pottery club. Someone had discovered that by adding MSB to the clear glaze when dipping pottery, one can more easily see where the glaze is and is not, assuring more complete glazing. Until this discovery, it was next to impossible for the potter to know exactly the area that was glazed, as the glazing does not show up on wet clay. The real beauty of this method is that in the firing, the blue is burned away and leaves a beautiful clear glaze!
A liquid fertilizer manufacturer found that Mrs. Stewart's Bluing added to his product in research experiments permitted him to follow the fertilizer through the plant and determine the rate of absorption.

Occupational Medicine departments and Drug Testing companies use Mrs. Stewart's Bluing. Nearly all large companies now require drug testing for new employees and some even require regular drug testing for all employees. This occurs via urine test. A little bluing in the water of the toilet can help to determine whether someone has "cheated" on a drug test. Many drug testing kits contain Mrs. Stewart's Bluing as the bluing agent used in the kit and many facilities purchase MSB directly for this purpose.
Mrs. Stewart's Bluing is useful when checking for leaks in drain systems, automotive cooling systems, and toilet tanks. By pouring a little MSB into a toilet holding tank, it is easy to see whether or not the tank leaks through into the bowl, wasting water. MSB is used with other applications to find or determine the presence of plumbing leaks as well. It is cost-effective and easy.
