Peter D Posted March 21, 2023 Share Posted March 21, 2023 I saw a video of someone painting a purple substance onto the white fibre ceramic lining of their smelting furnace, could anyone tell me what it is and what exactly it does. Quote Link to comment Share on other sites More sharing options...
Goods Posted March 21, 2023 Share Posted March 21, 2023 Not having knowing the video you are discussing, I can only assume it is rigidizer. Often, food coloring is added to give a visual indicator of coverage. The rigidizer binds the ceramic fibers at their intersections to give it more strength and reduce the potential of airborne fibers. Keep it fun, David Quote Link to comment Share on other sites More sharing options...
