CERMIGOLD INVESTMENT ENVELOPE 144X90GR
This outstanding phosphate investment has these advantages:
• Contains carbon for bright, gold-colored castings
• Expansion can be controlled to fit your needs -- yet technique is easy to follow
• Even extremely thin sections will be cast with sharp, clean margins just like lower-fusing golds
• Accurately fitting castings with smooth and clean surfaces -- without grinding. Uniform results time after time.
