Gold Glaze for Ceramics: Real Gold Luster vs Gold-Colored Glazes

Our quick answer

There are two kinds of gold ceramic glaze. Real gold luster (an overglaze such as Laguna Gold Coast or Colorobbia Bright Gold) goes over a fired glaze and needs a third firing to about cone 018 to 019; it gives true metallic gold but is never microwave safe and gives off fumes. Gold-colored glazes like AMACO PC-02 Saturation Gold fire with your normal glaze firing but look bronze or flecked, not mirror gold.

A gold ceramic glaze can mean two very different products. Real gold luster is a liquid overglaze with dissolved gold that you paint on a finished, glaze-fired pot and fire again at a very low cone. Gold-colored glazes and underglazes are ordinary glazes in gold, bronze or ochre tones that fire with the rest of your work but never look like polished metal. This guide covers both, with six picks and what each maker says about firing, microwaves, fumes and food surfaces. It is research-based: we compare maker pages, maker guides and US distributor listings, and we flag where they disagree.

Gold luster is never microwave safe: the metal can spark. Liquid luster contains solvents and gives off fumes when applied and fired, so work with ventilation and read the maker's SDS. No gold product here is a promise of food safety on your pots.

Real gold luster is sold by the gram. In October 2026, 2 gram bottles ran roughly $60 to $100 at US dealers and Laguna's 5 gram bottle sat around $120 to $140; gold-colored glazes are priced like normal pints. Check the live price, because gold luster prices move with the metal.

Real gold luster vs gold-colored glaze

Gold luster is an overglaze. Makers describe it as gold suspended in an oily resin medium; the resin burns away in a low firing and leaves a thin metal film fused to the glaze underneath. It needs a glazed, already-fired surface, and it takes on that surface's character: over a gloss glaze it fires bright, over a matte glaze it fires matte gold. Mayco, Laguna and Colorobbia's US distributor all list cone 018 or cone 019 to 018. The third firing is what makes it look like real gold.

Gold-colored glazes are regular glazes. They fire once with the rest of your glaze load at cone 5/6 or cone 10. They can be beautiful, with bronze sheens or gold flecks in a brown glass, but they are glaze color, not metal. Gold underglaze is the same idea at the underglaze stage: a yellow-gold or ochre color, with no metallic shine.

Other metallic looks, such as copper, bronze and pewter glazes, are covered in the metallic glaze guide. For how lusters fit with china paints and decals, see underglaze vs overglaze. Kintsugi gold lines on mended pots are a separate, non-fired technique: see kintsugi pottery repair.

Mayco discontinued its Duncan-era overglazes (OG801 Bright Gold, OG802 White Gold, OG803 Mother of Pearl, OG805 Premium Gold and OA901 Essence) in a notice dated September 2024 and points buyers to Laguna Lusters and Colorobbia Lustres. Older guides and jars still mention those codes.

1. Laguna Gold Coast LC201: best real gold luster

Best real goldLaguna Gold Coast Luster LC201, 5 g
Key specs Gold luster overglaze; cone 018; 5 g bottle; 6% metal (Laguna)

With Mayco out of overglazes, Laguna is one of the two luster brands Mayco now points buyers to, and Gold Coast is its gold. Laguna's instructions are short and clear: apply with a very clean brush over a smooth glaze fired to maturity, fire the fully dried ware to cone 018 with a fast fire and the peepholes open. For a shiny result, Laguna says to use a high-gloss glaze underneath; for a matte look, use a matte glaze.

Laguna says a light, even coat gives the best results for Gold Coast, and it says not to thin luster, because thinning causes streaking and dulls the metallic effect. It recommends mineral spirits for brush cleanup and a dedicated brush. On safety, Laguna says to work in a well-ventilated area, wear a NIOSH-approved respirator, keep lusters away from heat and open flames because they are flammable, and avoid breathing fumes or kiln exhaust during firing. It points to its luster SDS sheets for the details.

Gold content is where sources differ: Laguna's designer effects page says the lusters use a 6% concentration of metal, while a US dealer (Krueger Pottery) titles the 5 gram bottle "5.5%". Laguna publishes no food or microwave statement; as with any gold, keep it out of the microwave.

  • Type: real gold luster (overglaze)
  • Firing: cone 018, fast fire, peepholes open
  • Metal: 6% (Laguna) or 5.5% (dealer title)
  • Size: 5 g bottle
  • Cleanup: mineral spirits

Pros

  • Current US maker
  • Clear firing and safety instructions
  • 5 g goes further than 2 g bottles

Cons

  • High price per gram
  • Flammable and fume-producing
  • No food statement published

Who should skip it: Anyone without a well-ventilated kiln space, or who wants gold on mugs that go in the microwave.

2. Colorobbia Bright Gold Luster 8%: best small bottle for a first try

Best first bottleColorobbia Bright Gold Luster 8%, 2 g
Key specs Gold luster overglaze; cone 018; 2 g jar; 8% gold (title)

Colorobbia is the other luster brand Mayco recommends, and its Bright Gold comes in a 2 gram jar, which keeps the cost of a first experiment down. Colorobbia does not run a US product page that we could find, so the details here come from The Ceramic Shop, a US distributor, and Bailey Pottery's listing of Colorobbia's liquid metallics.

The Ceramic Shop's instructions match the classic method: apply one smooth coat, brush it out evenly and do not let the gold pool, then fire to cone 018. It strongly recommends a vapor respirator to avoid breathing the fumes. Its listing says overglazes can be used on surfaces that touch food and drink, but that ware decorated with gold should not go in the microwave. Bailey adds that firing temperature varies by type of ware, so check it against your clay body.

The 8% figure is the gold content in the product title. Colorobbia also sells other metallics (bronze, platinum, mother of pearl) through the same dealers, so you can test several effects in small jars. Two grams covers rims, handles and small accents, not whole pots.

  • Type: real gold luster (overglaze)
  • Firing: cone 018 (distributor)
  • Gold: 8% (product title)
  • Size: 2 g jar
  • Microwave: not for microwave use (distributor)

Pros

  • Small, lower-cost bottle
  • Mayco-recommended brand
  • Clear one-coat method

Cons

  • No US maker page
  • Details come from distributors
  • 2 g covers accents only

Who should skip it: Potters who want maker-published instructions in hand, or want to cover large areas.

3. New Mexico Clay NM801 Liquid Bright Gold: for former Duncan users

Duncan-style goldNew Mexico Clay NM801 Liquid Bright Gold, 2 g
Key specs Gold overglaze; witness cone 019 to 018; 2 g; 7% or 8% gold (listing differs)

New Mexico Clay ran the Mayco paint store and now sells gold overglazes under its own brand after Mayco's discontinuation. NM801 Liquid Bright Gold follows the old Duncan method almost word for word, which helps if your notes or class handouts were written for OG801.

Its page says not to stir or shake the overglaze, to place a little on a glazed palette and apply one smooth coat, and to brush metallics out so they do not pool. For solid coverage with Bright Gold, it suggests a yellow glaze or yellow underglaze underneath. Fire to witness cone 019 to 018 on stilts in a clean, well-ventilated kiln that is not overloaded. The page gives a useful fault check: underfired gold rubs off, and overfired gold cracks into islands.

The listing has two gaps. The page title says 7% gold and the product heading says 8%. It also says not to use Duncan Essence but then suggests Essence for wiping off mistakes. The store also lists NM805 Premium Liquid Bright Gold at 12%, out of stock when checked. The page carries a California Prop 65 warning for crystalline silica and gives no food or microwave statement.

  • Type: real gold luster (overglaze)
  • Firing: witness cone 019 to 018, stilted
  • Gold: 7% or 8% (listing disagrees)
  • Size: 2 g

Pros

  • Duncan-style instructions
  • Fault guide for under and overfiring
  • Higher-gold NM805 option

Cons

  • Inconsistent gold percentage and thinner advice on the listing
  • No food statement

Who should skip it: Anyone who wants one consistent maker sheet; Laguna's page is clearer.

4. AMACO PC-02 Saturation Gold: best one-fire gold-look glaze

Best gold-look glazeAMACO Potter's Choice PC-02 Saturation Gold Glaze
Key specs Cone 5/6 (Potter's Choice line); satin to matte dark bronze gold; pint, gallon
Mid-range tierCheck price on Amazon

If you want a gold look without a third firing, PC-02 Saturation Gold is the best-known option. AMACO describes it as a smooth satin to matte finish that fires dark gold, similar to bronze. It is part of the Potter's Choice line, which AMACO lists for cone 5/6 (cone 5 at 2,167°F, 1,186°C; cone 6 at 2,232°F, 1,222°C) on bisque fired to cone 04.

AMACO's key instruction is that it needs a heavy application to develop its gold metallic finish. Thin coats will look brown. AMACO positions it for sculptural work, industrial ware and accents on artwork, not as a liner, and the product page prints no food-safe statement in its text. Treat it as a glaze for the outside of vases, sculpture and decorative pieces.

PC-02 comes in pints and gallons; AMACO notes the dry dipping version carries different health labels, so read that label if you buy dry. Its sister PC-01 Saturation Metallic is a satin metallic black that resembles steel. For Spectrum's gold glazes, see the Spectrum gold glaze review.

  • Type: gold-look stoneware glaze
  • Firing: cone 5/6 (Potter's Choice line), bisque cone 04
  • Finish: satin to matte, dark bronze gold
  • Application: heavy coat needed
  • Sizes: pint, gallon

Pros

  • Gold look in your normal cone 6 firing
  • No luster fumes
  • No extra firing

Cons

  • Bronze rather than bright gold
  • Needs heavy coats
  • No food statement in the page text

Who should skip it: Anyone who wants mirror-bright gold, or a gold surface on the inside of mugs and bowls.

5. Mayco SW-178 Fool's Gold: best gold-fleck glaze for functional ware

Best gold flecksMayco Stoneware SW-178 Fool's Gold Glaze
Key specs Cone 6 ox, cone 10 reduction; glossy brown with gold flecks; pint
Mid-range tierCheck price on Amazon

Fool's Gold is a gold glaze for pottery you actually use. Mayco describes a rich brown base with tiny gold metallic flecks, glossy and semi-transparent, that breaks translucent and pools darker over texture. The gold here is a sparkle in brown glass, not a metal coat, so it suits mugs and bowls where luster would wear and could not go in a microwave.

Mayco lists cone 6 oxidation and cone 10 reduction, and at cone 10 the color darkens with metallic mottling. One coat lets the clay show through; two to three coats deepen the color. Mayco's photos are on white clay. The product page shows the Dinnerware Safe mark and the ACMI seal, and it comes in pints.

Mayco does not specify brushing versus dipping on the page, but as a Stoneware pint it is a brushing glaze. Like any glossy brown that pools, keep the bottom third a little thinner on tall pieces until you know how it moves in your kiln.

  • Type: glaze with gold metallic flecks
  • Firing: cone 6 oxidation, cone 10 reduction
  • Coats: one to show clay; two to three for deeper color
  • Label: Dinnerware Safe mark, ACMI seal
  • Size: pint

Pros

  • Gold sparkle in a normal firing
  • Dinnerware Safe mark
  • Pools nicely on texture

Cons

  • Reads as brown with flecks, not gold
  • Pint only

Who should skip it: Anyone who wants a solid gold surface or who fires low fire.

6. Mayco UG-058 Harvest Gold: the closest thing to a gold underglaze

Gold underglaze colorMayco Fundamentals Underglaze UG-058 Harvest Gold
Key specs Underglaze; cone 06 ox, cone 6 ox, cone 10 reduction; 4 oz, pint

People search for gold underglaze, but no underglaze fires to metallic gold: metal effects need a luster on top of fired glaze. What underglaze can give you is a gold-yellow color for painting, and Mayco's Fundamentals UG-058 Harvest Gold is a good example with a wide firing range.

Mayco lists Harvest Gold for cone 06 oxidation, cone 6 oxidation and cone 10 reduction. At cone 06 it fires matte without a clear; at cone 6 the color concentrates; at cone 10 reduction it fades. For stronger color or for dinnerware, Mayco says to apply clear or matte clear glaze over it, and names SW-001 Stoneware Clear for cone 6 and cone 10. The page lists it as dinnerware safe with a clear glaze and shows the ACMI seal. Sizes are a 4 oz jar and a pint.

There is a practical link to real gold, too: New Mexico Clay suggests a yellow glaze or yellow underglaze under Bright Gold for solid coverage. For the wider Fundamentals line, see Mayco Fundamentals underglaze.

  • Type: underglaze color (not metallic)
  • Firing: cone 06 ox, cone 6 ox, cone 10 reduction
  • Clear: SW-001 at cone 6 and 10 (Mayco)
  • Label: dinnerware safe with a clear glaze, ACMI seal
  • Sizes: 4 oz, pint

Pros

  • Wide firing range
  • Paints fine detail
  • A good base under gold luster

Cons

  • Not metallic
  • Fades at cone 10 reduction

Who should skip it: Anyone expecting shine from an underglaze alone.

How to apply and fire gold luster

These steps combine what Laguna, Mayco's former guide, New Mexico Clay and the Colorobbia distributor publish. Always follow the instructions and SDS for the bottle you buy.

  1. Start with a pot that is already glaze fired. A glossy glaze gives bright gold; a matte glaze gives matte gold.
  2. Clean the area so it is free of dust and finger oils, and work in a clean, dust-free, well-ventilated room. Laguna recommends a NIOSH-approved respirator.
  3. Do not stir or shake the bottle. Use a clean, dry brush kept only for luster.
  4. Apply one smooth, light coat and brush it out so it does not pool. The wet color is not gold: Mayco's guide said Bright Gold looks brown and Premium Gold red when applied correctly.
  5. Let it dry (Mayco's guide said about one hour), then load on stilts in a clean kiln that is not overloaded.
  6. Fire to cone 018 (Laguna, Colorobbia distributor) or witness cone 019 to 018 (Mayco, New Mexico Clay). Laguna says to fire fast with peepholes open. Stay out of the kiln room during the firing unless the kiln is vented.
  7. Clean brushes with the cleaner the maker names (Laguna: mineral spirits).

Makers publish cones, not degrees, for this firing. Lakeside Pottery describes its cone 018 gold firing as about 1,300°F (704°C); the pottery cone chart explains why the exact temperature depends on heating rate. A kiln vent is worth having before you fire lusters indoors.

Gold pottery glaze and food: what makers say

Makers do not agree on gold and food, so read the label on your exact bottle. Mayco's former overglaze guide said gold overglazes can be used on surfaces that contact food and drink, but should not go in microwave ovens, and warned that the gold will eventually wear away with dishwasher use and hard scrubbing. The Ceramic Shop says the same for Colorobbia. Laguna publishes no food or microwave statement for its lusters.

Gold-colored glazes are labeled like any glaze. Mayco shows a Dinnerware Safe mark on SW-178 Fool's Gold; AMACO's PC-02 page text gives no food-safe statement and AMACO positions it for sculpture and accents.

No label is a promise about your pot. Results depend on firing to the stated cone, application and testing. Gold luster must never go in a microwave, and many potters keep it off lips and eating surfaces, where it wears fastest. The food safe glaze guide covers testing.

How to choose gold glaze for pottery

Real metal or gold color

If you want something that reads as gold leaf from across the room, only luster will do it. If you want warmth and sparkle that survives daily use, choose a gold-colored glaze like Fool's Gold or Saturation Gold.

Your kiln and the extra firing

Luster needs a third firing at a very low cone. Most electric kilns with a digital controller can fire cone 018, but check your controller manual for low-fire programs. Luster fumes need ventilation; a kiln in a living space without a vent is a poor match.

The base glaze

Luster copies the surface below it. A smooth gloss glaze, such as a low-fire clear Mayco lists as luster compatible (S-2101), gives the brightest gold. Rough or matte glazes give a soft gold. New Mexico Clay suggests yellow underneath for solid Bright Gold coverage.

Where the gold goes

Rims, handles and small accents are the usual places. Lip contact and dishwashers wear luster, and microwaves are off limits, so think about how the pot will be used before choosing where to paint it.

Budget and bottle size

Luster is priced by the gram, and 2 grams covers accents, not whole pots. Buy the smallest bottle first and test on a tile or a second-quality pot. Mayco's former guide also said not to stir or shake, which means the bottle needs careful storage, capped and upright.

Other metallic effects

White gold, platinum and mother of pearl use the same method. Mayco's guide said that when combining gold and mother of pearl, apply and fire the gold first, then the mother of pearl at cone 020. Mayco's Opal Lustre line has its own review: Mayco Opal Lustre.

Common gold luster mistakes

Purple, streaky or patchy gold: the coat was too thin or uneven. Add another smooth coat and refire.

Gold that rubs off: underfired, per New Mexico Clay. Check a witness cone.

Gold cracked into islands: overfired, per New Mexico Clay.

Drips on vertical surfaces: too much luster in one spot; brush it out.

Dull gold on a shiny pot: dust, oils or a dirty brush. Clean the surface and keep a brush only for luster.

Safety notes

Liquid luster contains solvents and is flammable: keep it away from heat and open flames, work with good ventilation, and wear a NIOSH-approved respirator as Laguna advises. Avoid breathing kiln fumes during the luster firing, and vent the kiln as its maker specifies. Read the SDS for your bottle before use. Glaze-colored products contain silica once dry, so wet-clean your work area. Never microwave gold-decorated ware, and never promise anyone a gold-decorated pot is food safe.

Frequently asked questions

Is gold glaze food safe?

It depends on the product and the maker’s label, not on the gold color. Mayco shows a Dinnerware Safe mark on SW-178 Fool’s Gold, while Laguna publishes no food statement for its gold luster. Gold luster wears with use and must never go in a microwave, and no label is a promise about your pot.

Can gold luster go in the microwave?

No. Mayco’s former overglaze guide and The Ceramic Shop’s Colorobbia listing both say ware decorated with gold should not be used in microwave ovens. The metal film can spark and damage the pot and the oven.

What cone do you fire gold luster to?

Laguna and Colorobbia’s US distributor list cone 018, and Mayco’s former guide and New Mexico Clay list witness cone 019 to 018. It is a separate firing after the glaze firing. Use a witness cone and follow the bottle’s instructions.

Why did my gold luster turn purple?

Purple or streaky gold usually means the coat was too thin or uneven. Apply another smooth, light coat over the area and refire to the same cone. Dust or oils on the surface can also dull the result.

Is there a gold underglaze?

Not a metallic one. Underglazes come in gold-yellow colors such as Mayco Fundamentals UG-058 Harvest Gold, but they fire as color, not metal. For a metallic gold, apply a gold luster over fired glaze and fire it again at a low cone.

How much real gold is in gold luster?

Makers and dealers list figures from about 6% to 12%: Laguna says 6% metal for its lusters, Colorobbia Bright Gold is sold as 8%, and New Mexico Clay lists a 12% Premium gold. Higher gold content usually costs more per gram.

Can you put gold luster over a matte glaze?

Yes, but it fires matte. Laguna says to use a high-gloss glaze for a shiny result and a matte glaze for a matte look, because luster copies the surface under it. Rough or textured glazes give a softer gold.
