    Hello all, A quick question if someone would please clarify for me... 

    I have always used  boric acid + alcohol  as a fire coat. Borax is a
    different material isn't it?  I only use borax to cure crucibles
    before melting...a very glassy coating. 

    My concern, from reading on this forum, borax can be the cause of
    damage to some sapphires and rubies by etching the surface. 

    Would someone please confirm for me that they are different...Or
    correct me if needed. 

Thank you,
Mark
