They are compatible for use under most clear glazes. We suggest that you try them with one of our clear glazes (400, 700, 800 or 900 Clear Gloss cone 06\/04, 250 Satin Clear cone 06\/04, 1100 Clear Gloss cone 4\/6, 1120 Clear Satin cone 4\/6 or 1200 Clear Gloss cone 9\/10). Unlike many other brands of underglaze we use a frit base rather than a slip (clay) base for our underglazes. The advantages to the user are that our underglazes can be applied on greenware or bisque and they can be used with or without a clear glaze covering. When used without a clear glaze cover they have a matte velvet like surface. However, when used without a clear glaze cover they are not considered dinnerware safe because the rough surface can be difficult to clean and can encourage bacteria growth. Our color chart shows the unglazed color in the upper left half of the tile and the color when covered by a clear gloss glaze in the lower right half of the tile. The color chart samples were fired at cone 05. Our underglazes generally have good temperature stability up to cone 6 and for many colors to cone 10. When fired hotter than cone 04 you may get small color variations from those shown on our charts, so please test them for your application. Some of our underglaze colors will start to look glossy without any clear glaze cover at cone 5. These softer colors are 507, 530, 537, 538, 544, 552, 560, 567 and 568. Our underglazes can be intermixed to create your own colors. However, we recommend not mixing 561, 562, 563, 567, 568, 569 with any of the other colors. These colors are based on cadmium encapsulated stains that do not mix well with other ceramic stain colors. All of our underglaze colors are lead-free, A\/P non-toxic and dinnerware safe when covered with a dinnerware safe clear glaze.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Spectrum

We suggest that you try them with one of our clear glazes (400, 700, 800 or 900 Clear Gloss cone 06\/04, 250 Satin Clear cone 06\/04, 1100 Clear Gloss cone 4\/6, 1120 Clear Satin cone 4\/6 or 1200 Clear Gloss cone 9\/10). Unlike many other brands of underglaze we use a frit base rather than a slip (clay) base for our underglazes. The advantages to the user are that our underglazes can be applied on greenware or bisque and they can be used with or without a clear glaze covering. When used without a clear glaze cover they have a matte velvet like surface. However, when used without a clear glaze cover they are not considered dinnerware safe because the rough surface can be difficult to clean and can encourage bacteria growth. Our color chart shows the unglazed color in the upper left half of the tile and the color when covered by a clear gloss glaze in the lower right half of the tile. The color chart samples were fired at cone 05. Our underglazes generally have good temperature stability up to cone 6 and for many colors to cone 10. When fired hotter than cone 04 you may get small color variations from those shown on our charts, so please test them for your application. Some of our underglaze colors will start to look glossy without any clear glaze cover at cone 5. These softer colors are 507, 530, 537, 538, 544, 552, 560, 567 and 568. Our underglazes can be intermixed to create your own colors. However, we recommend not mixing 561, 562, 563, 567, 568, 569 with any of the other colors. These colors are based on cadmium encapsulated stains that do not mix well with other ceramic stain colors. All of our underglaze colors are lead-free, A\/P non-toxic and dinnerware safe when covered with a dinnerware safe clear glaze.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Spectrum Pottery Glazes","offers":[{"title":"501 WHITE","offer_id":51868366733683,"sku":"SP501GL","price":105.0,"currency_code":"USD","in_stock":true},{"title":"505 ORANGE","offer_id":51868366766451,"sku":"SP505GL","price":105.0,"currency_code":"USD","in_stock":true},{"title":"508 BABY PINK","offer_id":51868366799219,"sku":"SP508GL","price":105.0,"currency_code":"USD","in_stock":true},{"title":"512 WALNUT BROWN","offer_id":51868366831987,"sku":"SP512GL","price":105.0,"currency_code":"USD","in_stock":false},{"title":"515 BLACK","offer_id":51868366864755,"sku":"SP515GL","price":133.0,"currency_code":"USD","in_stock":false},{"title":"517 LIGHT GREY","offer_id":51868366897523,"sku":"SP517GL","price":105.0,"currency_code":"USD","in_stock":false},{"title":"522 TEA","offer_id":51868366930291,"sku":"SP522GL","price":105.0,"currency_code":"USD","in_stock":false},{"title":"525 LIME GREEN","offer_id":51868366963059,"sku":"SP525GL","price":105.0,"currency_code":"USD","in_stock":false},{"title":"532 SKY BLUE","offer_id":51868366995827,"sku":"SP532GL","price":105.0,"currency_code":"USD","in_stock":true},{"title":"534 LAVENDER","offer_id":51868367028595,"sku":"SP534GL","price":105.0,"currency_code":"USD","in_stock":false},{"title":"537 COBALT BLUE","offer_id":51868367061363,"sku":"SP537GL","price":133.0,"currency_code":"USD","in_stock":false},{"title":"544 BURGUNDY","offer_id":51868367094131,"sku":"SP544GL","price":133.0,"currency_code":"USD","in_stock":true},{"title":"556 LIGHT GREEN","offer_id":51868367126899,"sku":"SP556GL","price":105.0,"currency_code":"USD","in_stock":true},{"title":"557 LEAF GREEN","offer_id":51868367159667,"sku":"SP557GL","price":105.0,"currency_code":"USD","in_stock":true},{"title":"562 BRIGHT RED","offer_id":51868367192435,"sku":"SP562GL","price":133.0,"currency_code":"USD","in_stock":false},{"title":"565 BRIGHT PURPLE","offer_id":51868367225203,"sku":"SP565GL","price":165.0,"currency_code":"USD","in_stock":false},{"title":"568 CHRISTMAS RED","offer_id":51868367257971,"sku":"SP568GL","price":133.0,"currency_code":"USD","in_stock":false},{"title":"570 HOT PINK","offer_id":51868367290739,"sku":"SP570GL","price":133.0,"currency_code":"USD","in_stock":false},{"title":"571 DANDELION","offer_id":51868367323507,"sku":"SP571GL","price":133.0,"currency_code":"USD","in_stock":false},{"title":"572 SPRING GREEN","offer_id":51868367356275,"sku":"SP572GL","price":105.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/5508\/2050\/files\/SP5654OZ-2_26b89670-b5c3-4828-8b11-0a1ac888c7c8.jpg?v=1730731709"},{"product_id":"spectrum-glaze-majolica-series-8-oz","title":"Spectrum Glaze Majolica Series (8 oz)","description":"\u003ch1\u003eSpectrum Glazes 300 Series Majolica Colors\u003c\/h1\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003eGlaze Type: Underglaze\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSpectrum Glazes 300 Series Majolica Colors\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eSpectrum Majolica 300 Series Glazes are as versatile as they are beautiful.

Artists can then brush designs onto the piece with the majolica glaze.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eMajolica Colors – A highly versatile product which can be used as a majolica color on top of a white base glaze or as an underglaze color underneath a clear glaze or as a glaze on its own.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eFor majolica technique first apply 2 or 3 coats (depending on how heavily you apply each coat) of our base white glaze (i.e. 799 Majolica White for cone 06\/04 firings or 1118 White for cone 4\/6 firings) over the entire piece. After the white glaze has thoroughly dried you can proceed to decorating with the 300 series colors. One coat will give you the traditional majolica look, in which some of the base white shows through the color. For opaque coverage 2 coats of color will be required.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eFor use as an underglaze use the 300 series as you would our 500 series underglazes (i.e. 1 coat – semi-transparent, 2 coats- semi-opaque, 3 coats- opaque) and then cover the entire piece with clear glaze (i.e. 700 Clear for cone 06\/04 firings or 1100 Clear for cone 4\/6 firings).\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe 300 series Majolica Colors can also be used as a glaze on its own, over a wide temperature range from cone 06 to cone 5. It will fully vitrify at cone 06 but the surface will not be quite as shiny as our 700 series glazes. At cone 5 most of the colors will show little color change, except the pinks and purples, which are not quite as temperature stable.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eUsing a zinc-free clear glaze, such as 1100, will improve results at stoneware temperatures.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eAll of the majolica colors are lead-free, dinnerware safe and A\/P non-toxic.\u003c\/span\u003e\u003c\/p\u003e","brand":"Spectrum Pottery Glazes","offers":[{"title":"301 WHITE","offer_id":62677328757107,"sku":"SP3018OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"304 YELLOW","offer_id":62677328789875,"sku":"SP3048OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"305 ORANGE","offer_id":62677328822643,"sku":"SP3058OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"307 ENGLISH ROSE","offer_id":62677328855411,"sku":"SP3078OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"308 BABY PINK","offer_id":62677328888179,"sku":"SP3088OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"315 BLACK","offer_id":62677328920947,"sku":"SP3158OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"320 LIGHT BEIGE","offer_id":62677328953715,"sku":"SP3208OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"321 SAND","offer_id":62677328986483,"sku":"SP3218OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"326 MID GREEN","offer_id":62677329019251,"sku":"SP3268OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"328 CHARTREUSE","offer_id":62677329052019,"sku":"SP3288OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"329 DARK OLIVE","offer_id":62677329084787,"sku":"SP298OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"330 HUNTER GREEN","offer_id":62677329117555,"sku":"SP3308OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"332 SKY BLUE","offer_id":62677329150323,"sku":"SP3328OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"334 LAVENDER","offer_id":62677329183091,"sku":"SP3348OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"337 COBALT BLUE","offer_id":62677329215859,"sku":"SP3378OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"350 SALMON","offer_id":62677329248627,"sku":"SP3508OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"352 ROSE","offer_id":62677329281395,"sku":"SP3528OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"353 LILAC","offer_id":62677329314163,"sku":"SP3538OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"354 ROYAL PURPLE","offer_id":62677329346931,"sku":"SP3548OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"362 BRIGHT RED","offer_id":62677329379699,"sku":"SP3628OZ","price":12.0,"currency_code":"USD","in_stock":false},{"title":"363 BRIGHT ORANGE","offer_id":62677329412467,"sku":"SP3638OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"365 BRIGHT PURPLE","offer_id":62677329445235,"sku":"SP3658OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"368 CHRISTMAS RED","offer_id":62677329478003,"sku":"SP3688OZ","price":12.0,"currency_code":"USD","in_stock":true},{"title":"370 HOT PINK","offer_id":62677329510771,"sku":"SP3708OZ","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/5508\/2050\/files\/Untitled_design_52.png?v=1775141671"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/5508\/2050\/collections\/Untitled_design_99282d08-8555-43ea-b40f-a506dedcf58a.png?v=1786648302","url":"https:\/\/www.sheffield-pottery.live\/collections\/spectrum-underglazes-majolica-rac-pens-ceramic-stains.oembed","provider":"Sheffield Pottery Inc.","version":"1.0","type":"link"}
