If you have purchased our crystals in the past you will notice a difference in appearance and packaging. We have recently brought on-line a new polishing process which provides a superior surface polish.

To clean the crystals, soak in alcohol, preferably methanol. The crystals should be held in this solution until ready for film growth. Attempt to use the crystals as soon as possible after cleaning. Avoid steaming cleaning, water based cleaning agents and moisture. Use only soft lens gauze to wipe the crystal surface.

We are constantly striving to improve our products. If you have suggestions in this regard we would welcome your comments.
