🎥 5 Tips for Successful Glazing in Ceramics

The video provides 5 essential tips for achieving successful glazing in ceramics. 1) Measure the glaze density correctly by performing a pre-test immersion on a similar scrap piece. 2) Mix the glaze thoroughly and pass it through a sieve to avoid lumps. 3) Clean the pieces thoroughly to prevent defects like pinholes. 4) Test-fit the piece in the glazing container before immersion to ensure proper fit and rotation. 5) Apply a releasing wax to the bottom or foot of the piece for a professional finish. The host emphasizes practicing and not discarding pieces if glazing fails initially.




Glazing refers to the process of applying a glaze or liquid glass coating to a ceramic piece. It is a crucial step in pottery and ceramics, as it provides a protective and decorative finish to the piece. In the video, the instructor emphasizes the importance of proper glazing techniques and provides tips to achieve a successful glazing result.


Density refers to the thickness or consistency of the glaze solution. The video stresses the importance of measuring the correct density of the glaze before applying it to the ceramic piece. The instructor recommends performing a test dip with a small sample piece to ensure the density is appropriate for the piece being glazed. If the glaze dries too quickly or too slowly on the sample, adjustments to the density may be required.


Mixing the glaze thoroughly is crucial to ensure an even distribution of the glaze components. The instructor advises mixing the glaze well before application, as the glaze tends to settle at the bottom of the container. Various tools like knives, forks, spoons, or whisks can be used for mixing. Proper mixing helps prevent defects and ensures an even application of the glaze.


Sieving, or straining, the glaze is recommended to remove any lumps or clumps that may have formed. The instructor warns that these lumps are undesirable and can lead to defects in the glazed piece. Passing the mixed glaze through a sieve or strainer before application helps eliminate such lumps and ensures a smooth, consistent application.


Cleaning the ceramic piece thoroughly before glazing is essential to avoid defects. The instructor suggests using a damp sponge to wipe away any dust or debris from the piece's surface. This step helps prevent small pinholes or imperfections from appearing in the glaze, which can be caused by trapped particles or contaminants.

💡Test Fitting

The instructor recommends performing a test fit of the ceramic piece within the glazing container before actually dipping it in the glaze. This involves simulating the dipping motion with the piece and the empty container to ensure that the piece can be maneuvered and rotated properly inside the container during the glazing process. This step helps prevent issues that may arise if the piece does not fit properly in the container.

💡Wax Resist

Wax resist, or resurgent wax, is a type of wax that is applied to specific areas of the ceramic piece, such as the base or feet, to prevent glaze from adhering to those areas. The instructor suggests applying wax resist to the feet or base of the piece before glazing, which results in a professional, clean finish in those areas after the glazing process.


The instructor acknowledges that glazing is a skill that requires a significant amount of practice to master. They reassure viewers that it is normal to make mistakes in the beginning and emphasize the importance of perseverance. Even if a glazing attempt fails, the piece can be cleaned and tried again after allowing it to dry thoroughly, typically for at least 24 hours.


The instructor uses the word "dramatic" multiple times to describe the glazing process, highlighting how it can be a stressful and challenging moment for pottery students. They acknowledge that glazing is often one of the most difficult steps in ceramics and that students tend to become anxious and stressed during this stage. By using this descriptive term, the instructor underscores the importance of proper glazing techniques and the need for guidance and practice.


The term "professional" is used by the instructor to describe the desired outcome of a successful glazing process. By applying techniques such as using a wax resist on the base or feet of the piece, the instructor suggests that the finished product will have a professional and polished appearance. This term emphasizes the goal of achieving a high-quality, refined result through proper glazing techniques.


Five tips for properly glazing ceramic pieces.

Measure the glaze density correctly by testing on a small sample piece before glazing the main piece.

Mix the glaze thoroughly to prevent settling and strain it to remove lumps.

Clean the ceramic piece thoroughly to remove dust and prevent defects like pinholes in the glaze.

Test fit the piece in the glazing container before dipping to ensure proper clearance for rotating and immersing.

Apply wax resist to the foot or base of the piece to achieve a clean, professional look.

Don't worry if the first attempts at glazing fail, it takes practice. Clean off the glaze and try again after the piece fully dries.

The glazing stage is often the most dramatic and stressful for ceramics students.

Use a densimeter or follow instructions to determine the correct glaze density for your piece.

Mix the glaze thoroughly with a knife, fork, spoon, or whisk to incorporate any settled material at the bottom.

Clean the piece with a damp, well-wrung sponge to remove dust before glazing.

Test fitting the piece in the glazing container first can prevent glazing failures due to lack of space for rotating and dipping.

Use a dedicated brush to apply wax resist only to the foot or base area before glazing.

If the initial glazing attempt fails, clean off the glaze thoroughly, allow the piece to fully dry for at least 24 hours, then try glazing again.

With more practice, glazing results will improve.



Ciao a tutti e benvenuti sul mio canale


nel video di oggi voglio darti cinque


consigli per smaltare correttamente lo


so che il momento la smaltatura è un


momento drammatico normalmente da un


momento super drammatico per tutti i


miei allievi per cui quando arriva quel


momento lì iniziano tutti a sudare e a




so che quel momento è uno dei più


difficili in realtà in ceramica per cui


so quanto non sia semplice smaltare


correttamente quindi in questo video


voglio darti cinque consigli per


riuscire avere un buon risultato il


Primo consiglio che ti voglio dare e


misurare correttamente la densità c'è un


video su YouTube disponibile nel mio


canale in cui ti spiego come utilizzare


il tuo insieme quindi se non hai il


densimetro o se non sai qual è la


densità che ti serve per il tuo pezzo in


realtà è molto facile scoprire devi


sempre avere a disposizione prima di


smaltare un pezzettino da immergere come


prova per cui tenta che quel pezzettino


lì sia molto simile in quanto spessore e


in quanto materiale Ovviamente ha il


pezzo che devi smaltare quindi fai


sempre prima una prova nella quale


immergi questa rovina e tu devi proprio


vedere che quando togli si rovina dallo


smalto si deve asciugare immediatamente


Se non si asciuga subito vuol dire che


la densità non è corretta quindi è da


aumentare oppure da diminuire però


l'importante è quando tu smalti la


provina sia subito ben asciutto e che ci


sia almeno un millimetro di spessore o


più o meno di smalto sopra perché


altrimenti vuol dire che ce n'è troppo




secondo consiglio mischia sempre molto


bene il tuo smalto perché tende sempre a


depositarsi in fondo per cui tu puoi


anche passare con un coltello con una


forchetta con un cucchiaio con il


frullino Non importa in realtà il modo


che utilizzi per mischiarlo ma


l'importante è mischiare quel deposito


che si crea in fondo Inoltre dopo averlo


mischiato devi sempre passarlo al


setaccio Ricordati di me perché


altrimenti ti ritroverai i grumi e


quelli sono illegali terzo consiglio


pulisci sempre molto bene tutte le tue


forme Dalla polvere quindi semplicemente


puoi farlo prendendo una spugna


bagnandola strizzandola molto bene e


pulendo il pezzo Dalla polvere questo ti


eviterà un sacco di difetti come ad


esempio quei piccoli buchini che si


presentano ogni tanto nello smalto


quarto consiglio questo ti sembrerà


veramente strano però è super utile


quindi Ascoltami prima di immergere il


tuo pezzo nel contenitore che hai scelto


fai la prova quando il contenitore è


vuoto Cosa vuol dire prendi il pezzo con


la pinza e fai finta di immergere per


capire se effettivamente questo pezzo ci


stava oppure no all'interno del


contenitore il più delle volte quando


vedo fallire qualche smaltatura e


proprio perché il pezzo non si riesce a


girare all'interno di questo contenitore


per cui Assicurati che il contenitore


sia adatto


Quinto consiglio passa la cera


risorgivante nei piedini dei tuoi


manufatti o nella base se non c'è un


piedino e così riuscirai ad ottenere un


risultato super professionale e molto


semplice prendi la cera riservate con un


pennello che utilizzi solo per quello


passi bene questa cera nel piedino


aspetti che si asciughi dopodiché


ti vengono super professionali super


puliti e non farai nessuna fatica


se le prime volte sbagli con lo smalto


Davvero non preoccuparti È normale


bisogna fare tanta tanta pratica se


sbagli non è da buttare via tutto il


pezzo basta pulirlo anche sotto l'acqua


Quindi togli tutto lo smalto pulisci


tutto il pezzo Lo fai asciugare bene


Quindi almeno 24 ore e dopo puoi


riprovarci quindi rituffare il tuo pezzo


più allenamento fai meglio verrà


ci vediamo al prossimo video Spero che i


miei video ti siano utili Spero che


questa lezione ti serva perché uno dei


momenti più drammatici è proprio questo


e ricevo tantissime domande proprio su


questo argomento qui quindi spero che


questo video ti sia utile Ci vediamo


alla prossima
