[Jewelry making - Article 00078] - Re: [Orchid] Firescale Prevention During Vacuum Casting

Dear Lee,

    I have a question. 

    The main reason for our cast to get oxidized is the contact with
    oxygen in the air, right? 

    What happens if I use the Vacuum Bell on my casting machine to keep
    my casted flask from the air in the first minutes of the casting? 

    I think it may work, but what concerns me is that the plexiglass of
    the Vacuum Bell could melt by the heat of my just casted flask. 

    What do you think? 

    Thank you and best regards,
