Cleaning 24x24 Inch Glass at Work Tonight

Doing some preparatory work for next week's 24x24 inch Ambrotype attempt. 15-24x24 3mm glass and 2-24x24 4mm glass were washed and albumized (edge).

I can tell already the 3mm glass will be much too fragile at this size. All future clear glass buys will be at the 4mm thickness. I already managed to slightly damage 4 plates. Working the 3mm glass to complete Ambrotypes without breaking glass, will be very difficult.

Note* Preparing the glass before the shoot will probably become a routine for me. It saves so much time in the field, allowing for quicker shooting (especially in the right light).
