Powder Bloom

8 g Sheets: 4 ×0.8 — Bloom 200 instead of 160

Sheets of any grade swap one for one: a sheet’s weight already matches its strength.

Assumptions

Sheet strength by grade: bronze 125–155 Bloom (we use 130), silver 160, gold 200, platinum 240.
Weight of one sheet: bronze 3.3 g, silver 2.5 g, gold 2 g, platinum 1.7 g. Sources differ slightly.
That is why sheets of different grades swap one for one: 4 silver sheets = 4 gold sheets.
Граммы пересчитываем линейно: граммы × Bloom рецепта ÷ ваш Bloom. По данным производителей желатина (GMIA) для одинаковой плотности нужно ~2% желатина 175 Bloom и ~1,3% — 275 Bloom; линейный расчёт даёт 1,27%.
If the powder pack doesn’t state the Bloom, keep 200 — an average powder strength.
A Knox envelope (US) holds about 7 g of powder, roughly 4 silver or gold sheets.
