Is the Coors Ceramics High Form Crucibles shatter resistant?
We use coors crucibles in the lab I work in. I am not an expert in ceramics, but can give you 12 years of observation. The coors crucibles are durable and sturdy if used properly. You must take care in heating and cooling to avoid possible thermal shock. Also, do not use if cracked and chipped. Invisible cracks can be detected by the sound of lightly tapping the crucible with your finger nail. If it rings it is good, if not, avoid using it. Look on the ColePalmer site for more accurate details on handling these types of crucibles and their temperature ratings. Hope, this helps.
