I’ve been working with fused glass off and on for about 2 yrs. Last year my mother gave me some gold powder that my grandfather used in interior paint 75 years ago. The gold is real but I don’t know the carat weight although I think it’s 24K. I would like to use this in fused glass as you would glass powders. I do not have my own kiln but the person who’s kiln I use is OK with anything I try. I work with 90 COE. Do you think this is possible? Any help would be greatly appreciated.

The best way to find out is to use some (you can mix it with clear glass fine frit or powder and aloe) place it on a small 2″ x 2″ glass – crystal clear would be your best bet – let it dry than cover it with a piece of clear and fire it at full fuse temp.
Glass and metals can react with each other – like red glass turns black where it is touching fine silver. I don’t know if this would be the case with gold and colored glass, this is why I suggested the crystal clear. Experimenting is the key of the game – with just small amounts of coarse.

Thanks Petra for you information and help. I will try the combination you suggested. Does the aloe have to be pure aloe or can it be the aloe gel that I have at home for sunburn with a few additives?
Thanks again for all your help,

I tried to make a coaster just to see what would happen with the gold powder. I used different colored frit and added the powder to it between two 3″ clear glass circles. The edges fused before the frit and powder melted and a gas occurred in the middle of the circles creating a bubble that is at least 1 1/2 to 2 inches across and 1/2 inch high. The glass in the middle of the bubble didn’t melt but created a rattle. I did find out that the “gold” powder is mostly copper. I have a beautiful blue “blob” on one side and you can see copper splotches on the underside. Although it really looks cool and I won’t be doing this again curiosity wants me to to see what I’d get next time.
