Hi Stephanie,
half to an hour a sieve once you've done a few, which probably makes them less 
than half the price of the, too small, 100mm diameter brass Endicote type 
sieves. The mesh, which we do get from Locker Wire Co (shame that I never 
noticed they produced wire mesh but may have decided against it 25 or so years 
ago on the grounds of how do you fasten it to bowls!!) is nylon and extremely 
robust. I think it correct to say that the bowls and/or stitching have always 
given way first and several of our bowls have been in service for some years. 
Bowls are the most vulnerable because the dryng ovens too easily get turned up 
too high. We tend to use 2mm, 1mm, 500 and 300 micron although sometimes use 
commercial garden sieves, ca 8mm, to remove the largest stones after the sample 
has been weighed/volume taken.

Does no-one else out there make their own sieves?

Jacqui
