Preserve bread loaves and rolls for a decorative display or centerpiece that lasts for months. Moisture inside the bread should be removed to reduce the growth of mold and to extend the usefulness of your decoration. Using several types of bread with a variety of grains, colors, shapes and sizes adds interest and balance to your centerpiece. Keep breads looking golden brown and appetizing by sealing them in a shiny, see-through layer of varnish.
Place bread loaves or rolls in a microwave oven for 20-second intervals on high power until the bread sounds hollow when tapped.
Use a flat-head screwdriver to open a small can of clear-coat semi-gloss polyurethane varnish.
Stir the polyurethane varnish thoroughly with a stir stick.
Dip your paint brush into the varnish and blot away the excess.
Coat one side of the bread completely with the polyurethane varnish and set it on the uncoated side to dry for 30 minutes to an hour.
Turn the bread over and coat the rest of the loaf with the polyurethane varnish. Again, let it dry for 30 minutes to an hour.
Continue adding polyurethane varnish until you have given each piece of bread four or more coats.
