APT-II Mend -a- Mold
In the past,
everything from condensed milk to Elmer's waterproof glue has been
used - and with some degree of success.
Disadvantaged of Using Milk or Glue
Condensed milk grows bacteria in your mold and comes apart leaving
mildew on surface and sour odors after a few castings.
Elmer's waterproof glue is so thick that you're unable to get a tight
fit, which results in a larger seam line. Also, the moisture absorbed
into the mold during slip casting is trapped behind the waterproof
glue film, causing the greenware to hang up in mold and not release
properly. Also, the greenware will have a hot spot where water has not
absorbed correctly.
Advantages of Using Mend-a-Mold
Mend-a-Mold prevents bacteria growth.
Mend-a-Mold allows water from the slip to pass through the glue film
without releasing the glue. Therefore, the mended area eliminates hard
spots on the greenware, and ensures the mold will release properly
when emptied.
