Gavj75 Posted December 25, 2018 Share Posted December 25, 2018 Recently I read that u can make ridgidizer by mixing fumed silica powder with water but as I can't find the post I read this in I can't be sure. Can someone please tell me if this will work and be ok to put on my ceramic fibre insulation? Thanks Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted December 25, 2018 Share Posted December 25, 2018 Yes you can make ridgidizer from fumed silica. Once it's mixed with water it is colloidal silica. https://www.iforgeiron.com/topic/43583-coating-for-kaowool/ Quote Link to comment Share on other sites More sharing options...
