Greetings to all!
I am trying to reproduce "bowls" - similar to sediment bowls
found on the carburetor of early gasoline/oil engines. These are in
various sizes, up to a diameter of 3". I have had the use of a cast
iron split mold, of 1"size. A press/blow mold, this allowed for an
interesting learning experience.
The task is to fabricate blow molds in a variety of sizes at a
reasonable cost. Cast iron is the material of choice however the cost is
justified only if there is a need for many pieces. I would like to
explore slip casting using a castable ceramic. There are a number of
formulations available however the costs are such that much could be
spent in experimentation finding the right product.
I would be very grateful to hear from anyone who may have had
experience with such products. I also welcome any input on what you may
feel is a better approach to the problem. It would be a delight to hear
from our colleagues in the hot glass community.
Many thanks, Bob
