Who Knows Nigel?

Posted by Site Moderator Webmaster on Sunday, October 23, 2016, In : Lapidary 

Not many people in our club know Nigel Brown, but behind the scenes he must be one of our most productive lapidaries, in and among all his other commitments. His website has been listed in this newsletter’s advertisements for several months now (nigelbrownjadecarver.com). When I looked at it again recently I saw he had been busy producing jade kiwis so I asked him for an update of his work. He sent us this:

THE SECRET OF A GOOD POLISH – IS A GOOD PRE-POLISH

Posted by Site Moderator Webmaster on Sunday, August 28, 2016, In : Lapidary 

In the bad old days, one cut facets on a 600 mesh lap, followed by a 1200 mesh lap and then went on to polish. The 1200 mesh leaves quite deep scratches, and on some material produces ‘orange peel’, a mottled surface with alternating rough and smooth patches. This makes polishing tedious. A pre-polishing step, with 3000 mesh or 8000 mesh diamond gets rid of the scratches and any orange peel. You might think the additional step adds time to the process, but in practice it speeds it up beca...

The Romance of the Stone

 “The Romance of the Stone?!”

 

 

-        excitement at having found a special piece of rough that asks for faceting

-        carefulness to get the right design for the rough

-        caution by previewing the new design on GemCad first

-        fear to start new designs or try different types of stones

-        bravery to just do it

-        patience to remove the initial surplus rough and reach the centre point and s...

Sing in the New Year

Posted by Site Moderator Webmaster on Monday, February 23, 2015, In : Lapidary 

André Bergh gave a talk and demonstration of what were described in the last newsletter as “quartz singing bowls”. But as things turned out, the bowls were made of frosted glass, in China. There was a selection in various sizes, and they are tuned to musical notes. When tapped with a drumstick, or using one in a stirring motion rubbing against...

The Tigers Leave for the Jungle

Posted by Site Moderator Webmaster on Monday, September 23, 2013, In : Lapidary 
Do you remember the Hout Bay tigers mentioned in our July newsletter? They are now finally free of their Namibian “African Dream” granite and leave for the “jungle” this week after seven months of dedicated work by Robin Kutiniyu. Each block originally weighed about 5 tons, and now is about 2,5 tons. The tigers’ bodies were worked to a high polish, and their stripes etched in freehand afterwards, with tigers eye cabochons inserted in their faces to help them see. Their bases will be...

Hunting for Tigers in Hout Bay

Posted by Site Moderator Webmaster on Monday, June 24, 2013, In : Lapidary 
Who would have thought there were tigers lurking in Hout Bay?

In amongst the warehouses of Mariners Wharf, surrounded by chunks of picture stone, granite, rose quartz, sodalite and ironstone, and with an all pervading smell of oily fish, you will find Robin and his tigers. This is a stone carver extraordinaire who brings an amazing sense of movement and reality to his work. His current project of life-size tigers creeping through the undergrowth is his biggest challenge to date.


I was first int...

Introduction
... Lapidary is a hobby that is enjoyed by people of all ages and circumstances. Unlike most hobbies, what you produce is actually worth more than the labour you put into it. For many cutters, their hobby becomes a part time, or full time profession.
