Reading Bill123's earlier post about an error in pot capacity (BPL Product Support branch), it should be noted that pretty much all the specs shown on the product webpage are wrong! Methinks the specs pertained to an old batch (the one with the ill-fitting lid) and the current mug/pot is altogether different:
Per BPL website:
Dimensions (height x dia.): 3.75 x 2.75 in (70 x 95 mm)
Total Weight: 2.8 oz (79 g)
Pot Only Weight: 2.4 oz (67 g)
Lid Only Weight: 0.4 oz (12 g)
Volume (BPL): 17.5 fl oz (500 ml)
Volume (FireLite spec): 18.6 fl oz (550 ml)
Per my measurements:
Dimensions (height x dia.): 3.125 x 3.625 (at pot bottom)
Dimensions (height x dia.): 3.125 x 3.875 (at pot lid)
Total Weight: 2.4 oz
Pot Only Weight: 2.0 oz
Lid Only Weight: 0.4 oz
Volume: 19 fl oz (562 ml) — filled to rim
Actually, I much prefer the new pot:
1. good-fitting lid
2. lighter weight
3. wider/squatter configuration is more efficient for my alcohol stove
4. slightly bigger capacity — I boil 16oz. of water at a time and this helps reduce the chance of water boiling over
I haven't seen the old pot, but I am thinking that the new pot's bigger dimensions and lighter weight are due to its thinner walls. You can squash this pot with one hand, so use with care.
