Permanent Hats become a permanent part of the marble product, providing a finished underside which requires very little, if any, additional finishing.  The hat is set in place on the un-gelled first cast immediately following vibration.  Gently depress the step-down part of the flange into the matrix just enough too barely cover it.  Because they conceal the underside of the bowl, any color of matrix can be used for the backpour. When the first cast of matrix has gelled and cooled, the second cast (backpour) can be made.  The permanent hats are available in a white or clear plastic, and with a choice of including an overflow, or no overflow. Marshall Gruber part numbers beginning with PH are permanent hats.

In addition to Permanent Hats, Marshall Gruber also manufactures Reusable Polyethylene Hats – which can be used repeatedly. However, Permanent Hats are convenient and cost-effective by reducing finishing labor costs.

Reusable Funnels are a convenient add-on to your Permanent or Reusable Hat. They are available in choice of round, oval or square pour holes to match your Hat.
