Yucky Wednesday

With countless artifacts displayed throughout the American Treasure Tour (which is to say, we have yet to count them all), it is inevitable that something on display might seem ... well ... maybe a little bit yucky.  Sorry if that word offends you.  Yucky things can be unpleasant, and that's not what we're generally about here.  Of course, they can also be helpful.  Helpful and yucky all at the same time.  Who knew?  So, today, we would like to highlight a container displayed on a shelf in the Toy Box - not far from our Prince Albert, I might add.  Something called French's Selected Calcined Plaster, for use by dentists.

Full disclosure here.  We at the ATT blog are not dentists.  We all thoroughly respect what they do, but we can't pretend to understand the art of their craft.  Calcined Plaster has proven somewhat significant in the making of dental molds.  When dentists apply water to the plaster, it becomes solid, such that it will preserve a shape once it dries.  The speed of its drying depends on the amount of water added.  One of its more significant functions is to cast the shape of a patient's jaw to help with the creation of dentures.  The canister of plaster displayed at the Treasure Tour was sold  by Samuel H. French & Co., whose offices were at 475-477 York Avenue in Philadelphia. They were in business in the late-1880's as building suppliers and providers of plaster.
