I have some old Guardian Service Ware and I am looking for the old handle for these pots
One pair is listed on etsy for $35 UDS; see tinyurl.com/
These vintage bakelite products tend to become become brittle or deformed. They contain asbestos and formaldehyde, and are no longer used for cooking and other high temperature household applications.
This one sold, and Im sure others will come up on this and similar sites
Here are handles that are listed for $15 & $40:
I'm very familiar with the Guardian Service cookware but I'm not sure if you're asking about the long clamp-on handle or the handle covers/grips.
The two handle grips/covers are okay but they sometimes become 'unstable' after a lot of use.
Some of the modern long handles grips do not fit properly on this cookware as they were made for other types of cookware.
All of these 'handles' will be expensive so I'm wondering if you have tried just using oven mittens/gloves or even nice pot holders as the cookware handles are easy to grip.
