Lusters are a ceramic merchandise used to add valued alloy accents to porcelain or china ( think the gold brim on plates ). however, they can besides be used on glass. today we ’ rhenium adding aureate and Palladium polka dots to already fused donuts, and painting some donuts with Mother of Pearl luster .
safety

  •  Wear a respirator with VAPOR filters.  The essence and the lusters themselves contain powerful solvents that are very bad for you to breathe.
  • Wear gloves, ditto with the solvents, bad for your skin as well.
  • The solvents are volatile, so it’s a good idea to seal up all of the used paper towels or whatnot in a plastic bag before throwing them away to contain the fumes.
  • Check with the luster manufacturer about food safety if you are making functional ware, it’s better to be safe than sorry!!

exploitation LUSTERS
It is identical comfortable to cross contaminate your lusters, so I recommend making a kit for each individual luster that contains a dedicated paint brush, a give bottle of Essence ( solvent ) and an extra bottle to use for brush wash. Keep each luster kit separate to prevent cross contamination.

To apply lusters :
Shake the bottle to make certain the color is thoroughly blend. If the luster is thick and gooey, add ONE DROP of perfume and mix again. If it ’ second inactive gooey, add ONE DROP of effect and shuffle again. Over cutting is not actually a problem you can fix, so avoid it .
Dip your brush tap into the luster and key it onto the glaze. One coat alone, try to make it even. Mother of Pearl can be applied in swirls to give more ocular sake, or as a smooth coat .
After painting, try to get american samoa much luster out of the brush and rear into the bottle as possible. Wash the brush in the supernumerary bottle with Essence in it so you don ’ t contaminate all of the Essence with washed out luster .
glass can be fired ampere soon as the shininess is dry .
gold shininess :
Gold Luster comes in a bantam 2 gram bottle, is quite expensive ( around $ 28US ) and can be purchased at most ceramic supply stores. The luster is red before arouse, so don ’ triiodothyronine be surprised when your looking glass looks odd !
After firing they look like this ( firing schedule at the end of the article ) .
Palladium Luster
palladium shininess fires to a bright silver or white gold semblance. This luster besides comes in a bantam 2g bottle, and is about the same price as the amber. It is a molasses brown semblance before arouse .
And after firing ( firing schedule at end of the article )
mother of Pearl Luster
One of my favorite lusters, Mother of Pearl gives an iridized, oil satiny kind of color to glass. It is well less expensive, around $ 8 US for a 1/2 oz bottle. This luster is cobalt blue in color before arouse :
Since this is a quite translucent luster, I ’ molarity painting the entire doughnut rather of fair dots :
And after displace :
Lusters fire to cone 020 according the the manufacturer, that translates to 1180F if you look at a cone temperature conversion chart. ( Cone is the measurement used in ceramics firing. It international relations and security network ’ deoxythymidine monophosphate truly relevant for glass without converting it to temperature. Visit my favorite cone temperature conversion chart. )

I used this arouse schedule :
250/hr to 500, hold 10
300/hr to 1100 halt 5
off and cool to room temperature
This discharge schedule works great for small pieces. Since we are firing the glass to just above annealing temperature, for larger pieces, such as whole bottles, votives, etc. it is a good idea to add in an annealing stop. This would be a effective begin point :
250/hr to 500, hold 10
300/hr to 1100 carry 5
50/hr to 1060 accommodate 30
100/hr to 740, then off
Please TEST before you paint on an integral bantam bottle of gold !
thing TO REMEMBER :

  • Use glass bottles for brush washing or holding Essence!  The solvents will dissolve plastic, and flood your workbench causing an immediate need for evacuation until the fumes are gone (trust me on this one, not an experience you want to duplicate!)
  • Natural hair brushes work best
  • The luster is only as good as your glass, it does NOT act as a over spray, if you paint it on wrinkly glass, you’ll get wrinkly luster.
  • The firing temperature is very low, so this should be the very last step in making your glass art.
  • TEST!  Test glass colors with different lusters, and test firing schedules before doing a big project.
