Layering your fragile piece in different packing materials is one of the safest ways to keep your item from breaking while in transit. If you are packing a glass or ceramic vase or drinking glass, fill it with packing peanuts to keep the inside layered and cushioned.
Wrap your glass or ceramic piece in tissue paper, and use bubble wrap to add another buffer and prevent impressions from appearing on your glassware. Once you gently enclose the first set of layers with masking tape, it's best to place the item into a small box filled with packing peanuts or foam pieces before putting it in the larger shipping box.
Keeping the item wrapped and packed in a smaller box further minimizes the possibility for breakage.
Placing layers on the inside of your shipping box -- instead of packing each item in an individual box -- is ideal for stacking fragile items, such as ceramics and glassware. Create a moderate layer of bubble wrap, packing pellets or foam at the bottom of the box.
Wrap each individual dish or glass in old newspaper, and secure it with strips of tape. Use bubble wrap if you have extra fragile items.
Stack your items in the box from heaviest to lightest, bottom to top respectively, and add a final layer of packing material on top for added cushion before sealing up the box. The last layer will keep your glass and ceramic pieces from shifting in the box during the move.
If you want to keep your packing as simple as possible, opt for boxes that offer individual slots for your items. For example, stemware boxes provide individual slots for glasses.
It is still recommended to wrap each glass with at least one sheet of bubble wrap or newspaper for added absorption shock and to fill small spaces with packing filler, but the individual slots create a more stable environment for your items -- requiring less wrapping and less worrying.
