They claim it to be "laboratory tested." Again, countless letters have been received over the years telling us how effective a dab of Mrs. Stewart's Bluing is on a bee sting.

It was discovered long ago that a few drops of Mrs. Stewart's Bluing in the rinse water makes fine crystal sparkle, and does the same for mirrors and windows. We have had many reports that MSB used in the rinse water when cleaning crystal chandeliers extends the sparkle. 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?

The fact that Mrs. Stewart's Bluing mixes readily in any water-based solution makes it ideal to color the casting material used in podiatric 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.

We have always boasted Mrs. Stewart's Bluing as a non-toxic, non-hazardous, biodegradable, environmentally friendly product. It does have a non-toxic amount of an organic biocide and pH balancer, which is added to prevent algae build up in our mixing tanks. However, even in it's concentrated form, the amount is too small for government standards to label it as toxic or hazardous. We have asked the Septic Tank "Seal of Approval" people to test our product to be endorsed by them as safe for septic tanks. They are prevented in doing so by our small size. However, many loyal customers attest to it's safe use with septic tanks. Download our PDF MSB and Septic Tanks for more information.

A woman called several years ago looking for Mrs. Stewart's Bluing for use in her pottery club. After some questioning it was learned someone had discovered that by adding MSB to the glaze when dipping pottery, one can more easily determine the area which was dipped by the blue color. Until this discovery, it was next to impossible for the potter to know exactly the area which was glazed, as the glazing does not show up on wet clay. The real beauty of this method is that i 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.
