| I would like to know if it is ok to frame a document that is 288 years old between 2 pieces of museum glass so you can see both sides and also how to handle the document. Should I use a certain type of glove and where to purchase them at. I am in St. Louis, MO. |

No, it certainly is not ok to do that.

No.
A "sandwich mount" made with glass would promote condensation and result in permanent damage to the document, such as mildew and mold.
The problem is dew point; the environmental condition in which the glass surface temperature is about 20 degrees cooler than the surrounding air. Since glass is a poor insulator, the dew point condition may occur easily in normal handling and transport.
I suggest you consider an encapsulation mount using clear polyester film; Mylar-D or Melinex 516. If you need instructions for this, refer to "Mounting Objects with Clear Film", published by Columba Publishing, and available in the PFM Bookstore. Click on "Bookstore" in the blue area on the left of this page.
If you must construct a "sandwich mount", do it using abrasion-resistant, optically coated acrylic, such as Museum Optium Acrylic. This material would not be abraded by the document, and its thermal properties are such that condensation would not form (dew point would not occur) in normal conditions. Also, it is 98% UV-blocking, and the optical coatings make the glazing nearly invisible in proper lighting.
Be careful in framing such an old and irreplaceable document. Regardless of its monetary, historic, or personal value, you may be held liable for whatever damage may come from the framing.
