    I prefer pearlite to vermiculite due to the latter being able to absorb water from the air, just like the wood ash As far as an acid for etching suppliers, try googling art etching supplies or see if an art store near you can help you out If the volume of acid is dilute enough and in a small enough, then there are not any special handling
  • Annealing in Vermiculite - Bladesmiths Forum Board
    The vermiculite did work well when I used to use it, especially sandwiched between a couple of heated bars of steel like Alan mentioned It was my experience though that the coarser light colored vermiculite, hard to find these days, seemd to work better than the finer brown vermiculite more common now

  • Organic Gardening:Vermiculite vs. Perlite - Daves Garden
    I use fine vermiculite to avoid (totally) damping off of seedlings I used to have huge loss of seedlings to damping off but since using ½-1" of vermiculite as the growing medium over the compost, I have not lost a single seedling to the infection My big beef is that garden centres tend to massively overcharge for small volumes of vermiculite
  • Vermiculite versus Perlite? - Bladesmiths Forum Board
    I cannot find vermiculite to save my life right now, so I found some perlite at Wal-Mart it has volcanic ash in it and some other thing that slips me right now So has any one ever used it to anneal a blade Ed Cafferty in his knife making vid, uses vermiculite, to cool a blade over 12 hours to make it dead soft
  • Hypertufa 101: Make One Trough or Throw a Party - Daves Garden
    Perlite and or vermiculite We used perlite and didn't sift out the bigger pieces, so we had some pretty rough-textured mix Experiment with different combinations and see what you like Sand A layer of damp sand in a shallow box can help support your project, especially if you're putting the mix on the outside of your mold
  • Can you Substitute Pearlite for Vermiculite? - Metallurgy and other . . .
    I also think that the vermiculite would be the better insulator of the two I have also often heard of light powders, like MgO (lime), ash, and even cement powder being used Have aslo thought obout using refractory wool - I have seen a table that shows it is a way better insulator than pearlite and powdered MgO at least
