The media could not be loaded.I bought these as tools to use in supporting my bee pollinators. They worked great in the bottom of the kiln to brace my ceramic pieces between for glaze firing. My plans are to drill holes in them to create a piece of kiln furniture to stick the flower stems in to fire without getting glaze all over. Great value for the money. If using them in the kiln, be sure to run them through your kiln through a bisque fire to cure them before use!
