2005年12月20日 · A second or 2 in the electric coffee grinder will or should do it. Get a cheapie from Wal Mart.. 15 bucks I think. Plan to replace it often if you want to make lots of frit. The blades grind up too from the glass. They will last a bit longer when the glass is pre fractured. Use a strong magnet… waved over the frit after you lay out your glass.

2005年6月30日 · Now, dump the glass into the cup with the smallest screen and shake it a bit. What falls out will be mostly powder and doesn’t work well for beads. I discard that. Then dump what remains into the next size larger screen (over a bowl). The smallest frit will fall through. There’s one size. Now what remains will be larger frit and big chunks.

2004年4月17日 · There are a few reasons why you want to grind glass with a wet grinder. 1. Too much heat without water makes the glass crack 2. Grinding glass creates glass dust and particles that you do not want to inhale. When the glass is wet it keeps the particles damp so they don’t fly off into the air. Then later you clean out the bottom of the grinder ...

2004年7月13日 · The most important difference in glass made for furnace / off-hand glassblowing is the Coefficient of Expansion (COE). When you work with glass you need the COE of all the glasses to be within one or two points for the piece to be stable when annealed. Furnace glass is 96 COE or there abouts, Moretti / Lauscha type glasses are approx. 104 COE.

2009年10月15日 · I am pouring medium clear frit in a mold of a cross. I am putting the clear frit in the bottom of the mold, Dichronic glass next and clear frit in top. I have a paragon Kiln that uses cones. I have fired the frit using a cone 15 and fired a separate batch at using cone 13, both firings had so many bubbles it looked like frosted glass. Help!

2007年3月30日 · but I have seen mention at different places about using 96 frit and stringers, in moderation, on 104 Moretti glass, which seems to be more of a gap than 90 to 96. You can use Furnace Glass that has lead in it with other COE’s within reason, (usually as frit for surface application,) but You can’t mix Effetre with Bullseye or Spectrum glass.

2005年3月25日 · Well, if you are talking anout the furnace glass frits that are popular (at least I have a bunch of them ) then thses are a leaded glass with a lower COE, about 94 – 96 in most cases I believe. My understanding of Thompson’s enamels for glass is that they do not contain lead and were formulated to match the COE of the soda lime glass but I ...

2003年9月23日 · You can use several layers and position the mesh to make the size sieve that you desire. I make a bunch of frit, put it in the jar, arrange the screen with the smallest sieve size. I shake out the small pieces and bottle them. Then I remove or reposition a layer of screening and do it again, and again until I have sorted my desired frit sizes.
