For color enhancement was used a Rheinberg filtering system. (Not available in my store)For users willing to make pictures from large areas of the slide is recommended to put the slides between two linear polarizing plates and use a regular (phone) camera. Please notice: The attached pictures showed an area of the slide between 10mm X 10mm and 20mm X 20mm. To study the crystals a microscope a very low magnification is recommended at this stage. (Macro preferred) until the crystal maturation process will advance and higher magnifications will be required. Payment - For payment we accept PayPal and we ship only to an eBay certified address.
