Future Form Ceramic Molds are easy to use, and will be good for countless firings. Pre-drilled; always remember to elevate molds for proper air circulation. Use several coats of your favorite glass release. Make sure your mold is cured (no moisture from the glass separator) and you should have excellent results.
Mold measures 8-1/4" x 3" x 1/2" deep.
Use with a quality glass separator.
