 Working with Golden Luster

I'yard hither to help!

Every bit a ceramic creative person who adds golden luster to every piece I burn down, the well-about mutual emails I receive from other potters contain questions well-well-nigh how to apply aureate luster. More often than not, information technology seems like there'due s a scrap of trepidation involved, and so if y'all're curious nearly gilded luster, only unsure where to brainstorm, help is here!

I personally apply Duncan'due s Gold Luster Overglazes. They brand: "normal" vivid gilt if y'all just desire to get your anxiety moisture, premium bright golden for higher end work, a squeamish white aureate, and mother of pearl luster. I've simply worked with the golds, and then I can't give y'all tips on working with the mother of pearl.

A quick annotation on Female parent of Pearl: While this page is aimed at using gilded luster, I besides have experience with Duncan's Mother of Pearl. While mother of Pearl is more than straightforward than working with gold, I have 2 tips for working with it:

First, practise not layer mother of pearl with metallic lusters.

second, mother of pearl tends to bear witness castor strokes afterwards information technology has been fired, so i detect it near cute on my surfaces when I've been conscientious to keep my strokes going in the aforementioned direction.

Knowing the Cloth

Allow'southward start with the nigh basic question: What, exactly, is gold luster? Luster is an overglaze, meaning that it's applied over the vitrified, glaze-fired slice and requires a 3rd firing. Luster is fabricated of particles of real gold suspended in a liquid medium, ordinarily a pino oil resin. Later on existence applied to your piece, it's fired in guild to burn off the organic binder. What remains is a layer of real, melted gold on your slice. This is very different than gold leaf, which is applied with adhesive and isn't fired; lusters are permanently fired onto your piece.

Y'all can purchase lusters (including gold, silverish, platinum, mother-of-pearl, and more) from local clay suppliers and diverse online sources. If you finish upward loving the smooth that it adds to your ceramics, I would suggest checking with your supplier to meet if they offer bulk discounts. I use Duncan lusters non only because they piece of work well and are easy to discover here in the United states, merely also because they offer discounts when I lodge a dozen bottles at a fourth dimension. Gold luster isn't cheap, so information technology'southward definitely worth looking into. When ordering, keep in mind that each canteen is tiny—only ii grams—simply it will probably get further than yous recollect. I've read that a single two-gram bottle volition comprehend a 12-inch tall vase entirely, of class, how big or rotund that vase is would exist anyone'southward guess. For my employ, if I'm only adding gilded accents to the flowers on my mugs, I find that the canteen lasts a long 4th dimension. Merely, if I'm covering the unabridged handle on a prepare of large mugs, the bottle doesn't last for more than v–10 handles.

 Brushes

I apply a pocket-size brush designed to work with oil paint to apply luster. If yous get to your local craft store to sentinel out the brushes, you'll notice that they're divided into sections by size, shape, and the kind of medium that they piece of work all-time with. Brushes are sized by number, starting with the smallest at 0000 and upward to the largest size, 24. The lower the number, the smaller the castor. There are as well a variety of castor shapes. I've establish that a round brush is ideal for evenly spreading luster. Then, when picking out a luster castor, await for brushes that are created to utilize with oil pigment, are round in shape, and are most a size 0 (although the size may vary depending on what and how much surface expanse you're covering).

Tip: Keep your brushes dedicated merely to luster employ so that they don't become contaminated with anything else. I use dish soap and paper towels to clean my brushes off later on on use, and then set them bated to dry. I've been using the same 3 brushes for over v years, then this method seems to work well for me.

Application Safety

Employ a properly fitted respirator that blocks fumes during awarding, and piece of work in a ventilated space with plenty of airflow. Luster has toxic fumes when it'southward in liquid class. Equally long as the weather is prissy, I apply my luster exterior.

Application

You lot can utilize luster too thick or too thin. If the luster is practical too thickly on horizontal surfaces, you don't come across much of a difference, although you may stop up with the occasional cleft or bubble in its finish. When applied besides thickly to a vertical surface, even so, it does baste. I personally love when it drips; I discover it to be luscious and rich in appearance, and I often intentionally add together a thick dollop of information applied science to the base of my handles or on the tip of a bloom so it volition run down the pot.

On the other hand, if information technology's applied too thinly, data technology will appear nighttime royal and/or streaked instead of aureate. This is a problem on both horizontal and vertical surfaces. If this happens, y'all tin add a footling more luster to the area and fire the piece once more.

A terminal consideration when deciding how and where to use your luster is the surface quality of your piece. Gilded luster takes on the surface backdrop of whatever you put it on. This means that if yous utilise information technology on a shiny surface, it will exist shiny. If you lot use it on a matte surface information technology will be matte; and if y'all use it on a smooth surface it will be polish. For example, if I want to glaze the leaves of a flower with gold luster, fifty-fifty if I cansee the texture of the leaf through the glaze (either because the glaze is transparent or considering information technology breaks over edges), I demand to brand sure that the texture is really tactile instead of smooth (in other words, I can experience the texture through the glaze) earlier painting the foliage with gold. Otherwise I'll just end up with an opaque, foliage-shaped aureate splotch on my mug instead of a gilded, textured leafage.

Firing

When firing, brand sure that your kiln is either isolated away from your living/work infinite and/or well vented. The first 4th dimension I fired a luster kiln, I didn't realize that the fumes from my kiln were leaving the garage and wafting back into our living room window until it was also late, and I ended upward with a headache.

I burn gold luster to cone 018 in my manual electrical kiln. When I was first using lusters, someone recommended that I should apply my aureate and let information engineering science dry out for 24 hours before firing data technology. Nonetheless, I tin can exist impatient, so at present I tend to add together pieces to my kiln every bit I utilise the gold to them, shut the lid when I'm finished, and creepo it upward to high. It simply takes two–iii hours for my kiln to get upwards to temperature, and another 4 hours to absurd. I'm not necessarily recommending that you lot practise it this way, but I've never personally had any problems with data engineering. I piece of work with a cone one-half dozen porcelain from Kentucky Mudworks called White Lightening, which stands upward to my process beautifully, but you may need to be more patient and slow the process down a fleck depending on your clay torso and the size or thickness of your work.

Mistakes, Care, and Pricing

Cleanliness is of the utmost importance when using aureate luster. If you become even a trace amount of the oil on your finger and and then bear upon your piece, you lot'll end up with an cruddy imperial smudge on your pot later yous've fired it. I avoid this by just holding my mugs in my left hand, and just touching my luster brush with my right mitt, so that nothing cross contaminates.

Early on, I causeless that if I fired a piece back up to coat temperature (cone half dozen for me) that the golden would burn off and I could first over. That'due southward partly true, and may exist ane solution for stoneware or darker clay bodies. On porcelain, all the same, there is still a subtly tinted surface area where the golden one time was, so it's not actually a good fashion to correct mistakes. It's likewise an expensive solution. You're non merely paying for the luster, but you lot are also paying for the toll of some other kiln firing for that piece.

There is adept news though! Mistakes don't accept to last forever. Y'all tin can guild something called luster eraser from various ceramic suppliers, which will help eliminate backlog gold or fix mistakes. Merely, if you lot lot desire my personal secret, purchase Bar Keepers Friend (BKF) (in the powdered class) from the grocery store! Mix a pocket-sized amount of BKF with water to brand a paste, and using a Q-tip, or a toothpick for more than than fine particular and minimal elbow grease, you can remove the extra luster or eliminate mistakes.

I oasis't actually found gold luster to be dishwasher safety, that is, it depends on the blazon of detergent i uses in their dishwasher. Harsher dishwashing liquids can substantially weaken and deteriorate the gold cease. As such, I don't feel comfy universally declaring gold luster to be dishwasher prophylactic, and I always recommend hand washing all of my pieces. I've had some lustered mugs in use nearly daily, for several years, that are paw-washed with gentle soap, and the luster hasn't washed off. Also keep in mind that this is existent gold, which ways it'due south a metal and isn't microwave safe.

Finally, don't forget to factor the actress cost of using gold luster into the final cost of your work. Allow's say that you've paid $30 for a vial of gold luster and were able to decorate seven vases with information technology before it ran out. This ways that you need to add at least $four to your wholesale cost for each of those vases and at to the lowest degree $8 to the retail cost for that vase. Merely, in authenticity, you should be adding more than that considering you're also needing to exist paid for the awarding time likewise as the toll of a third kiln firing.

I hope that this helps you lot to incorporate gold luster or a luster of your option into your ceramics.

A special thank you to my photographer for this projection, Cindy Kane !
