Pack glass with ample cushioning and little movement to avoid breakage or destruction.
Glass is fragile enough sitting on a shelf in your home. Proper shielding and cushioning is key for sending glass shipments through the mail without causing damage. There are several best practices for packing glass in a way that will ensure it arriving in one piece.
The 'one box' method
If you’re only going to use one box, make sure that you have some soft, cushioned and non-marking material handy. “Non-marking” materials are anything that does not have ink or paint marks that may rub off during the shipping process. Newspapers are an example of marking material because of the ink's ease of rubbing off onto to glass throughout the shipment's journey. Tissue paper, wrapping paper, toilet paper, and bubble wrap are all great alternatives to using newspaper.
Place your object in the center of the box and then place your packing material of choice around the object in the box. Any hollow spaces in your object should be filled with the packing material as well. Your object should be held firmly in the center of the box by the material, but not so firm that it cannot move. It’s important that your piece of glass can move around slightly because this will allow some of the energy that comes from shaking the box to be absorbed by the packing material. Be sure to put packing material underneath and all around the item so none of its sides touches the box in any way.
The 'two boxes' method
This method is very similar to the one box method, but instead of sending the object after shielding it within one package, you can then shield the package inside of a larger box. This would be a good place to use newspaper or any cushioning material with ink or printing as it won't touch the item, itself.
NOTE: If you are using tape to enclose the packing material around the box, try not to attach tape directly to the glass object to avoid further damage.
