Jeff's interest range from anything to do with science, the arts, philosophy, writing and much more. He is really a jack-of-all-trades, and probably master of none.
However, working with glass and the arts are probably his main passion.
The Moh’s hardness scale refers to scratch hardness. The resistance of one mineral to be scratched by another.
Friedrich Mohs (1773-1839), a Viennese mineralogist, introduced the term scratch hardness. The scale ranges from the softest at 1 through to the hardest at 10. Gemstones with a hardness of 1 and 2 are considered to be soft, from 3 to 5 medium, with 6 and over considered to be hard.
Some of the gemstone names we commonly use can be very confusing, and often costly to those unaware. For example, ‘Indian Jade’ is actually Aventurine, a form of quartz. The reference to ‘Jade’ is confusing and simply incorrect.
On Saturday 22 September we were at the CUA Community Hub for their market for the Toowoomba Carnival of Flowers. Such a great day. The staff at CUA went all out to decorate the Hub with a great theme for the carnival.
We have to thank them immensely for their efforts and congratulate them on the day.
Just want to summarise for you what we have been doing over the last couple of months. Believe me, there has be a lot of that proverbial water go under our bridge. Some crystal clear and good, some not so much. But that’s life and we move on.
We make sure our glass products, Glass Art and Jewellery features, have all been carefully annealed to ensure strength and long life. However, you should care for Glass Art as it is still glass and misuse can result in damage.
