FF: gas fireplace ceramic inserts?

hello, in both of my gas fireplaces I have what seem to be ceramic cylinders to hold the flames of the fire – I have no idea what they are called, but as my fireplaces are nonfunctioning and my kids/dog/cat have been knocking into and breaking some I thought I would save the others from destruction and give them to someone restoring their fireplace. If you would like a picture or are interested in taking them, please leave your contact info here. pick up will be in ditmas park. thanks!
