Description
Hi-Heat Soldering Investment is a gypsum-bound investment that is ideal for any soldering job that requires the use of an oxygen-gas torch, or where an unusually fine and smooth soldering investment is wanted. Excellent for use with high-fusing ceramic alloys for both the pre- and post-soldering technique. Can also be used for soldering precision attachments.
