Like you say, there are many heavy cast iron skillets being sold today, but there are some that have been manufactured differently to be lighter. They should not be used on max heat though.

I think this is the one we have, but there are other brands than Ronneby Bruk.

» Ronneby Bruk 162600 40 x 26 x 7 cm Light Weight Cast Iron Fry Pan

That looks like a good one and it says it can even be used on induction burners.

I decided to look for some old frying pans at garage sales. I thought it would take a long time to find what I wanted. I went to only a few garage sales and found nothing but then I just happened to be at a very dear friends home and was telling him about my search for old cast iron skillets. He said “I think I have some old ones and you can pick one of them if you would like.” So, he went and got four old skillets and I was so surprised that one was a Griffith made in Erie Pennsylvania! He thinks it was his Grandfathers since his Grandfather owned some restaurants. He gave me this beautiful old family heirloom. It is a bit rusty but I can polish it up in no time!

Good! Don't forget to season it when you have scrubbed off the rust.

Yes, I look forward to seasoning it. Scrubbing rust off is probably not as fun!

You can try pouring vinegar into the pan and leave it overnight. I think it would make it easier to clean.

That is great idea!

Laziness is the mother of invention. :-)
