Got some time to try out the amber I got last week.

First off, a splinter that came off the first piece to play with.


Cut a slab from the heavily included piece with my foredome. a 2x1 inch section. Everything crumbled, and this was the only piece substantial, to be saved. Any further piece from this stone will from now on be numbered 1...something.



Will not do that again. After having everything crumbling on me. I took the long way round, and took the hacksaw to it. Resulting in fracture free starting-points.


Yesterday, I tried an extra that came with the shipment. I now got a new perspective and even more respect for people like Przemysław Kuś. In many ways, this stuff behaves like quartz crystal. Just as brittle, and no internal colour can be trusted. But, when it works, it works out great.Trying out splinters and breakaways from the amber I got. It looks like, one needs to stay away from inclusions as they are very weak points. Light touch, and very similar than working Quartz crystal overall. No wonder that the guys need such a huge piece to start with, if you need to clean it up and only use pure sections. The second piece I tried yesterday has nice colour, but does not seem to turn blue the way I see it at any angle. Nevertheless, it turned out interesting. Just trying to test how the light functions in this material. So no balance, but interesting despite of it.


And finally, a small piece that came off, while cutting a slabette from a cleaner piece (Number two something from now on).


So, needs a careful touch and preferably carbon burs plus slower speed. But I'm quite happy with what turned out today. Just needs to be finished with toothpicks to get into tight spaces.


Thanks for looking, Kurt

I hate working amber!  I have some of the Blue amber that my wife bought for me to cut and so far, I have one piece about 2/3s done.  Every time I think I am getting close I get the piece too hot and melt a section and I have to go back and sand out the melted area and start over. 

Love what you have done with the pieces you have.

Lower speed, and burs normally used on wood should do the trick. Will try not to do either, but if the colour gets better in other pieces, might invest in carbon bits and search for that danged foot-control. :)

My work was on a genie and sometimes, just not enough water and instant melt.  I'll get it right sooner or later but I need to cut more agates for the Agate Expo in July anyway so it can go on the shelf for a while.

Just received from New Zealand! Don't know yet how to work it, but I'll sure have a try!
Any advises?
