Some of us only have and use older glass carboys. I damn sure wouldn't trust any glass coming out of China. The old O-I stuff is remarkably durable, as is the older Mexican glass. They used to use those daily in office water coolers all over the country (1920s or so until the 70s or 80s) long...
I use the rubberized Therma-Fit gloves for handling glass. They grip better when wet, and give better dexterity under all conditions than thick welding gloves. If you are set on leather, get some TIG gloves with gauntlets.
Something like these...
Not surprising considering pressure is pressure, and it takes pressure to keep CO2 in solution. All else being equal, there isn't any more pressure in a bottle conditioned brew than there is in a force-carbed brew.
