We have finally started the season at Hanmer Springs. I will be there every Saturday from 9am to 2pm. ( Weather Permitting). We started a couple of weeks ago and I have already noticed how many people from NZ are now travelling in their own country. Heaps of people from Auckland and Nelson. Good to see NZ'ers travelling NZ.
A quick note about Dichroic glass:
Dichroic glass is notoriously hard to capture with the camera as it reflects back as you take the photo.I have tried to represent each piece as realistically as possible but please allow for slight differences in colour.
Modern dichroic glass is available as a result of materials research carried out by NASA and its contractors,[4] who developed it for use in dichroic filters.
Multiple ultra-thin layers of different metals (such as gold or silver); oxides of such metals as titanium, chromium, aluminium, zirconium, or magnesium; or silica are vaporised by an electron beam in a vacuum chamber.
The vapor then condenses on the surface of the glass in the form of a crystal structure. A protective layer of quartz crystal is sometimes added.[6] Other variants of such physical vapor deposition (PVD) coatings are also possible.
The finished glass can have as many as 30[6] to 50 layers of these materials, yet the thickness of the total coating is approximately 30[6] to 35 millionths of an inch (about 760 to 890 nm).
The coating that is created is very similar to a gemstone and, by careful control of thickness, different colors may be obtained.
The total light that hits the dichroic layer equals the wavelengths reflected plus the wavelengths passing through the dichroic layer.
A plate of dichroic glass can be fused with other glass in multiple firings. Due to variations in the firing process, individual results can never be exactly predicted, so each piece of fused dichroic glass is unique.[7] Over 45 colours of dichroic coatings are available to be placed on any glass substrate.[6]
