[Stoves] pot sizes /Re: Stoves Digest, Vol 37, Issue 24

[Lanny Henson]

Crispin and all,
You mentioned pot sizes.
There are stock pots, sauce pots and brazier pots.
Does you pot fit in one of these categories?
>From photos it looks like most pots used in developing areas are in the "sauce pot" category but many also use stock pots for the larger 60 liter and 100 liter size.
Links to Winco pot sizes. Different brands are different sizes but are close to the same size.

Stock pots

Sauce pots
http://www.wincous.com/search.asp?BigClassName=&SmallClassName=&keyword=sauce+pot&Submit.x=30&Submit.y=17
brazier pots

I am using a 40 quart sauce pot with the SLC but the pot shell is tall enough to hold a 60 qt stock pot which is about the same diameter.

  Dear Lanny

   

  It is unusual to find a pot that is taller than it is in diameter. I can't think of one in common use by ordinary people.

   

  But a soblok (rice steamer) is about 'square'. If you are familiar with engine stroke and bore, the common pots are 'oversquare'. 

   

  The implications are two: they are not all that tall, and the water sloshes to the side and over the lip with relatively greater ease per unit volume (per degree of tilt).

   

  The question of safety includes the pot supports and how spread out they are. A large diameter pot on a small support circle is dangerous. On 3 instead of 4 supports is more dangerous again.

   

  That is what I want to see tested. There are numbers that can be applied because the centre of gravity (CG) dominates the safe angle of tilt.

   

  Regards

  Crispin

   

   

  That is what I was thinking, I had already started typing a note.  I think the hazard of a bump and spill or splash is more likely than a tip over. A bump Like someone falling against the stove could dislodge the pot but not tip over the stove. The pot holders, the shape of the cook top and the foot print could affect the bump/spill/splash hazard.

  I am thinking that the height with a pot of 2 to 2.5  times the width of the base would be safe but 3 or 4 times would be getting dangerous. 

  This is for household size stoves, with larger stoves, you are less likely to have a force large enough to affect the stove.
