Subject: [Nhcoll-l] Air-abrasive kits for field work

Dear all,

We are thinking about options for an air-abrasive system for overseas field work. The main application will be removing the closely-adhered layers of sediment from the surface of lithics and fossils.

Does anyone have experience of any kind of portable air abrasive system or other set-up for this sort of application which might be suitable to take on an international flight from the UK to Tanzania? Ideally the pressure should be be adjustable between c. 40 and 80 psi and the system should be capable of firing 29 micron aluminium oxide powder.

The only option identified so far is a geological preparation 'air abrasive blaster' supplied by UK GE, which would require a compressor to be purchased on site but could be transported on a plane. If anyone has experience with the UK GE model or any other solution, we would be very grateful for your comments.
