I have a Glow Worm Revival gas fire and have been told that it is dangerous due to the fake coal being broken. It's snapped into a couple of pieces. Is this true and where the heck can I find a replacement? Also, what's it called? The best I can find is 'fuel effect' and that was £99. Surely it won't be that much? It's just one piece of soft ceramic type stuff, about 15 x 12".
