Inositol and copper sulfate
Track newly appearing axes separately from crystals already visible in the liquid. Compare the mixture with each component under the same imaging conditions.
Follow the field from liquid to its final visible form. Record the axes of new crystals against a fixed reference.
Calibrate north and check east in the image before treating a frame angle as a compass angle.

A laser experiment reported polarization-dependent selection of crystal structure. Under the microscope, log visible axes and onset time. Crystal structure requires a separate measurement.
Garetz, Matic & Myerson, 2002 ↗An earlier experiment reported polarization-dependent laser-induced nucleation. Compare onset and visible growth direction in a separate series under fixed illumination.
Garetz et al., 1996 ↗Published laser nucleation work provides an independent material for comparing onset and habit. Mark an axis only when the image gives a clear one.
Alexander & Camp, 2009 ↗In a controlled dish study with albumin, changes in wetting affected the final pattern. A salt-only control helps separate preparation effects from the added material.
Busscher et al., 2019 ↗Record the exact salt and vitamin forms. Compare the components individually before assigning a crystal axis or color pattern to the blend.
Steiner's 1924 Agriculture Course provides the historical context. Pfeiffer's sensitive crystallization work documents an image-forming practice with copper salts. Later experiments make preparation effects such as wetting part of the record.
Read the tradition and sources ↗The proposal is that the observer changes polarization at emission and that the light influences crystal growth. The orientation record describes the visible crystal axes. Testing the proposal calls for independent measurements of the incident light and blinded comparisons of separately prepared samples.
Follow the axes that appear as a liquid crystallizes. The north-aligned microscope provides a reference for studying visible growth alongside the image-forming tradition associated with Rudolf Steiner and Ehrenfried Pfeiffer.
Explore matter ↗Mark north and check east in the image. Keep the field, light and preparation conditions fixed, and record the first visible axes before comparing separate preparations.
A photograph, drawing or dated record can be sent privately for a personal reading. Include the procedure and the question.
