[Jewelry making - Article 00496] - [Orchid] Air trapped air wax mold

Hello,

    I've been experiencing problems with trapped air in the mold during
    wax injection. I'm using silicone to make my molds. I've tried to
    cut some vents and applied talcum in them to allow air to escape,
    but it is not working. Even doing that I've still got some regions
    not filled thoroughly in the model. Maybe I have cut vents in a
    wrong way. How is the correct way to cut or form mold vents? Is it
    possible to send me some mold pictures showing some examples of mold
    vents? 

    I would really appreciate that. 

Thanks.
Alfredo B. Gattai.
