The Campana lab » Otolith Microstructure Preparation

Pair #2a: Same otolith as previous, but after some polishing. The fact that some increments are visible when focused on the grinding surface indicates that polishing is nearly finished, and that the microscope magnification needs to be increased to better monitor polishing progress.

2021-3-25  MicroCloth® Polishing Cloth. 10.Clean and examine the otolith surface. The single sided preparation may create sufficient resolution of the rings. However, for larger otoliths, higher resolution may be obtained by polishing both sides 11.Place the slide back on the hot plate, just long enough to soften the Crystalbond Wax.

A method of mounting multiple otoliths for beam

2010-7-13  Preparation of otoliths for beam-based analysis frequently requires sectioning or grinding followed by polishing. Although preparation is relatively simple, the need to individually mount and prepare each otolith can limit the sample analysis rate (sample throughput) on beam-based analyzers.

Secrets for the best polished finish on your stainless

Make sure you clean the surface in between each grinding step using a microfibre cloth and cleaning agent. It is best practice not to mix different polishing compounds on absorbent polishing wheels, discs or mops. Don't apply too much pressure let the weight of the machine apply the pressure to the work. This will help to reduce the grinding

Grinding Glass from Rough Grind to Final Polish

The cerium is both a chemical and physical reaction with the glass so you do need some friction between the cerium and the glass to accomplish the polish. Polishing is not a fast step; in fact it will probably take you as long on the polishing stage as it took you to grind your piece from rough grind through to the Smoothing Pad pre-polish stage.
