New here, with a technical question. I don't have my own kiln, and use the one at my adult education class, so I don't have firing details.
Recently used crystal clear glass powder for the first time to "fill in" gaps on a chunky frit piece and when it came out of the kiln, the powder was not clear but a sort of transparent milky colour instead. That piece was tack fused. So then I tried just sieving some in different thicknesses on clear glass, (over a single blue stringer for colour contrast) to test it and did one on full fuse, and one on tack fuse with a similar result. Looks clear(ish) if there is a strong light behind it, but otherwise looks milky.
Were my expectations unrealistic - does clear powder always perform like this? (apologies for the bad photo!)failure with powder
