Just make the gold about 1/4 of the total final weight. Weigh your karat gold in grams (KGW) and calculate the total gold (Au) in grams. The silver needed: Ag to be added = 4Au - KGW. If you have 10 grams of 8KT (33.3% Au), you have 3.33 grams of gold and you would add, from the formula above: (3.33 x 4) - 10 = 13.33 - 10 = 3.33 grams of silver.
