For jewellers and technicians who mix investment powder for lost-wax casting, this flexible rubber bowl is a workshop essential. It helps you prepare a dense, bubble-free slurry for sharper, more detailed castings, and is available for our same-day dispatch target from our UK stock.

Key features

  • Flexible rubber walls allow you to squeeze the bowl to work out trapped air.
  • Smooth interior surface ensures easy cleaning and complete removal of cured investment.
  • Features a stable, flat base to prevent tipping during mixing.
  • Standard 4" x 5" size is ideal for jewellery and dental casting volumes.
  • Deep black colour provides high contrast against light-coloured investment powders.
