Anytime an item is shipped that is somewhat fragile such as a mirror, the possibility exists for breakage to occur but knowing how to ship a mirror properly can save the day. Regardless of the type of transportation or the precautions that are enacted to ship a mirror accidents do happen, some of which are not necessarily the fault of the transport company. Some mirrors have inherent flaws and weak spots that are exposed when shipping and result in a broken mirror upon arrival to their destination when moving. The best way to ship a mirror is to take as many precautionary measures as possible when packing and to hope the mirror arrives safely.
The best way to ship a mirror is to begin with a roll of masking tape that is one to one and a half inches wide. Place two long pieces of tape in the shape of an X from one corner of the mirror to the other diagonally, on both the mirror front an on the mirror back. In the open spaces around the large X you have made on the mirror make several smaller X shapes, again on both the front and back of the mirror. The basic concept of the use of masking tape to ship a mirror is to provide support for the mirror while still allowing it to have a bit of flexibility to bend a very small amount.
The next step to ship a mirror is to obtain pieces of Styrofoam sheeting that can be cut to fit the mirror. The Styrofoam should be cut slightly larger than the mirror itself, leaving an excess of about 2 inches around the edges of the mirror. After positioning the mirror between the Styrofoam sheets a series of small pieces of masking tape can be placed along the edges to seal the mirror firmly inside. When this has been completed, to ship a mirror properly requires that the entire package gets wrapped with bands of masking tape in a liberal fashion to hold it securely.
The final step to ship a mirror is to placed it inside of a cardboard container that is adequate for most forms of commercial transportation. A cardboard box can be purchased that is slightly larger than the mirror, and the mirror is then paced into the box and packed tightly using packing peanuts or even pieces of wadded up newspapers to serve as a cushion during the shipping process. Following all of the aforementioned measures designed for protection, you should be able to safely ship a mirror without incident.
