Standard Specifications to Request from Suppliers
When requesting quotes for Filter Coffee Davara Sets from Kumbakonam foundries, request these empirical technical parameters:
- Alloy Composition: Confirm whether the item is commercial brass (60% Cu, 40% Zn), high-ductility brass (70/30), or authentic bell metal bronze (78% Cu, 22% Sn).
- Base Wall Thickness: Heavy hand-hammered culinary pieces must measure between 2.0 mm and 3.5 mm (10–14 SWG). Reject pieces under 1.4 mm for high-flame cooking.
- Lining Certification: For all food preparation, demand double-wipe virgin tin (kalai) tested free from lead and cadmium.
- Rim Construction: Heavy patilas and kadhais must have a rolled solid brass collar rim to resist deformation during commercial handling.
