Huginn and Muninn in plaster, silica, chopped fibre sheet and grog!


  1. HI!
    Can you tell me what kind of plaster you are using here?
    I'm trying to find something similar to 'Fibrite' which a friend in France uses as a substate for her abstract artworks.
    Thank you for any help you can send my way,
    Jann Parkes

  2. Hi Jann,

    I think it's either casting or pottery plaster (depends on who orders for the studio) mixed with silica. I have been told that in general that plaster in Australia has a very bad quality compared to the rest of the world. The last layer is a mix of plaster, silica and 'grog'. Grog is what we Aussie's call a crushed fired ceramic, sometimes brick dust, sometimes more granular. I know some people use synthetic plasters and silicas for the first layer (for detail and good release finishes) Like Ransom & Randolph investment casting supplies. I hope that helps...where are you based? British Artist Angela Thwaites has a great book called 'mould making for glass'.

    I haven't heard of Fibrite (off to look it up)
