GAIWAN CAPACITY AND DRY-LEAF DOSE RECORD
Original Leaf & Brew Guide worksheet. Not a report of physical teaware testing.
Use room-temperature water for empty-bowl measurement. A cold fill does not establish hot-handling safety.

Gaiwan identifier and manufacturer/product link:
Advertised capacity and exact stated basis:
Manufacturer rim capacity, if stated:
Manufacturer in-use capacity, if stated:
Units and any word such as approximately:

EMPTY WORKING-FILL REFERENCE
Scale resolution and unit (g), or suitable measuring-vessel graduations:
Weighed configuration: bowl only, or another consistently documented configuration:
Dry empty mass:
Room-temperature water fill level and lid-fit observation:
Filled mass in the same configuration:
Water mass = filled mass minus empty mass:
Approximate water volume in mL at room temperature:
Repeated results, if taken, and observed range:
Reference chosen for future comparisons:

DRY LEAF AND RECIPE
Tea name; package instructions and brewing method:
Original dry-leaf mass in g:
Denominator chosen: [ ] empty working-fill reference [ ] measured newly added water
Water quantity used for this calculation, in mL:
Dry-leaf rate = dry-leaf g / stated water mL x 100:
If scaling: chosen rate x new reference mL / 100 = dry-leaf g:
Temperature and infusion time from the chosen instructions:

LATER INFUSIONS
Original dry-leaf mass remains the dose record; do not replace it with wet-leaf mass.
Infusion number:
Any rinse or prior infusion; draining/retained-water observation:
Newly added water, if measured appropriately, recorded separately:
Liquid poured out, if measured, recorded separately:
Any intentional leaf addition or removal:
What changed from the previous infusion:

The calculation organizes a recipe. It does not predict taste, prove equal extraction, prescribe a universal gongfu dose or certify teaware for hot use.
