I was buying some non-ceramic stuff online. My cart was to $48.99. They offered free shipping for orders of $50 or more. So I could either find something for a little more than a buck or pay $11.84 shipping. I sorted through their catalog and found the cheapest thing I could ever fantasize having a use for, a $7.95 brand unknown, 0- 600 gram pocket electronic made in China scale.
When I got it, it actually looked pretty well built. So I thought I would run some accuracy tests against my Ohaus. I have a couple of genuine Ohaus calibration weights to provide a standard of measurement. I could fiddle with the adjustments on my Ohaus and get it to acurately measure any individual or combination of my standard weights. However, when I would change the weights, it would be off a tiny amount on the new weight.
When I weighed a single or combination of my standard weights on the pocket electronic scale, on average, it was more accurate than my Ohaus. The errors on either scale were actually miniscule and of no significance in mixing glazes.
The significant outcome of my research project was that I could mix glazes, far easier, twice as fast and a little more accurately on my little $8 electronic scale. My Ohaus is now sitting on a back shelf.
The scale has no brand name but is model MS – 600. I see many extremely similar looking ones on eBay for about what I paid for this one. Some of them have higher capacities.
