Jewel 32 Stove

[skull181]

A nice Jewel 32 stove, and it's bits and pieces.

Nice name and makers stamp.

The question is this??

How do you get it to work?

What fuel is safest with out blowing myself up?

Any ideas?

Paraffin was the normal fuel for these type of stoves. Not sure about this type but you usually pumped the bottom cylinder with a small hand pump so the fuel was under pressure, The top part you lit so the top heated up to a point that you got a blue flame, similar to a paraffin blow lamp. The top part looks concave so i assume this is where the fuel is burnt to temperature. Looking at the markings it looks German but can't see that its marked up as a Jewel 32 stove, have you tried googling under the other names on the cylinder etc.

In picture 6 it says Benzin on it

Benzin is the German for Petrol

Yes , some of those old pressure stoves used petrol & I actually used one many years ago BUT I DEFINITELY would n't attempt using it these days !!!

I run a modern petrol stove and great it is, but these old stoves unless the parafin type I would want to overhaul before attempting to use it. They normally require preheating of the burner with meths normaly that sits in a little cup below the burner ( this is on the parafin type). Nice looking little stove, let us know if you ever get it going.
Best regards Weasel.

In good maintained condition they are not much dangerous. For example camping gas cartridges inside hot cars or leaking camping gas stoves in closed rooms can be much more dangerous. The filling plug of the Jewel has an over pressure valve inside. I come from the former GDR (DDR) and these stoves were standard equipment of millions of east german campers until the end of the east block. Still today I like using them on mountain trips to have the old camping feeling with the unique Juwel cooking sound One disadvantage to propane/butane stoves is, that it is a little dirty to work with them. But on the other hand they have a much more powerful flame compared to propane/butane so your water will boil really quickly.

These devices where built just until the 80s in GDR and nearly every family had one. Our Juwel looks exactly like yours and is GDR production. I don't know if war time Juwels were different?

General function is to heat up the stove until the petrol inside starts to evaporate. Once the stove works the heat it produces itself keeps the evaporation process continuing. For this the small groove on top of the tank is filled with petrol or better meths (as advised) as is does not produce soot (on cold days sometimes the groove has to be filled two or three times until it reaches the operating temperature). Inside the tank petrol (Benzin) is used and the quality of the petrol in relation to produce as few soot as possible is important for a regulary operation (we had some special type of petrol ("washing petrol" or "Katalyt") for these stoves but I don't know the english name of it). I hated nothing more than cleaning the soot from the aluminium pots when using standard unleaded fuel. If a flame comes out of the hole in the filling plug (overpressure valve), the preassure is to high (may be because of a dirty nozzle or dirty over pressure valve). If this occurs, turn of the flame and simply wait until it cools down to maintain it. But never open the filled and heated up stove as this will cause a darting flame injuring you!

Generally normal unleaded petrol will work but the nozzle will soon be full of soot so try to get less smoking petrol if possible when you want to use it.

It's a Juwel 34 not a 32.... as the new picture shows.

A german nick name of these stoves is "Barthels-Bombe", think It not needs translation But I still say that they are not more dangerous than most other stoves when operated and maintained properly. Most accidents with camping stoves occur because of wrong operation and trunken operators... And I have to correct my post, they are still produced and sold today in very slightly changed design.
