    Sodium Silicate Issue

    Hi All,

    I fired up the new forge on the weekend and it runs like a dream. Unfortunately my home made liquid glass sets to hard when the forge is fired up, but then in no time at all it melts and turns into glass. I would suggest there is too much silicate in it but that is the only thing i can come up with. Any thoughts?

    I am planning on watering down the mixture and trying again. It kept sticking to my steel in the forge.

    Additionally i have brought some high temp mortar and was going to mix this up and paste it all over the walls and in the base of the forge. Again thoughts would be appreciated.

    Cheers,
    CCS.

    Thought's???? don't follow DIY recipes for refractory from the net?

    Seriously if the recipes for homemade refractory worked then everybody would use it and not buy the proper stuff.

    First of all. Are you building a gas or coal/coke forge??

    Fair comment. Obviously someone from the net has managed to work it out otherwise they wouldn't be making it (and video's on how-to?) surely.

    As for the forge. I have built a gas forge following the revelations on my charcoal forge burning my neighbors car with embers (see previous posts). It is lined in 2" kaowool and then my homemade (rather glassy) sodium silicate solution sprayed on top of that to prevent the fibres from flying everywhere. Fueled by a Gameco eco burner.

    Then if it's a gas forge with 50mm isowool lining you need to spray it with ridgidiser to stop the fibres flying around. Again use the right product for the right job.
    They make ridgidiser to do the job your trying to do, just use it.
    If you have trouble getting ridgidiser Pm me.
