Pasler Wax Resist for Pottery Bisque or Greenware, Glaze and Slip Application, 16 fl oz / 473 ml Review (2026)

What this wax resist is for

This is a water-based wax resist meant to be brushed onto bisque or greenware before applying glaze or slip, most commonly to keep the foot of a piece bare so it will not stick to the kiln shelf during firing. Once dry, the wax repels water-based glaze and slip so they bead away from the treated area instead of coating it, and the wax itself burns off cleanly at low temperature during firing, leaving unglazed clay behind with no cleanup needed. Being formulated for use on both bisque and greenware gives it flexibility across different stages of the studio process, since some resist products are only suited to one stage or the other. The listed natural drying time is described as fast, which keeps pieces moving through the glazing workflow without long waits.

Formulation and application

The product is described as a non-toxic, water-based liquid with no strong odor, which makes it comfortable to use in a shared studio space compared with older solvent-based resist products. It brushes on with moderate viscosity, meaning it is thin enough to spread evenly without excessive dripping but thick enough to give solid, even coverage in one or two coats. Because it works on greenware as well as bisque, potters can use it earlier in the process, for example resisting a foot ring before a piece is even fired the first time, which is not always possible with resist products formulated only for bisque. As with any wax resist, thin and even application gives more predictable results than thick, uneven coats that can pool or take longer to dry.

Cleanup and handling

Like other wax resist products, brushes used to apply this one need to be washed with warm soapy water immediately after use, since dried wax is very difficult to remove from bristles and will ruin a brush left uncleaned. Many potters set aside a dedicated brush just for wax resist rather than risk contaminating a glaze or underglaze brush. Being water-based rather than solvent-based, spills and drips on tools, hands, or work surfaces clean up more easily than older latex or solvent resist formulas, especially if wiped up before the wax has fully dried. Mistaken applications in the wrong spot are still difficult to correct once the wax has set, so careful brushing matters more than fast cleanup for avoiding errors.

Value and bottle size

At 16 fl oz, this bottle is sized for potters who resist feet and other areas regularly rather than occasionally, and the larger volume brings a lower cost per use compared with smaller specialty bottles. Pasler is a newer name in ceramic supplies compared with long-established brands like AMACO or Mayco, so potters switching from a trusted supplier should expect a short adjustment period while learning how this particular formula dries and performs on their own clay body and glazes. For studios or individual potters doing frequent glaze firings, the bigger bottle and dual bisque-or-greenware use make it a practical everyday resist rather than an occasional specialty purchase.

Who should buy this wax resist

This product suits potters who want one wax resist that works across both greenware and bisque stages, rather than needing separate products for each. The larger 16 fl oz size fits studios and individual potters doing regular glaze firings who want to avoid running out mid-project. Beginners will find the water-based, low-odor formula easy to work with in a shared space, while more experienced potters doing resist decoration will appreciate the flexibility to apply it earlier in the process on greenware. As with any resist product, remembering to clean brushes immediately after use matters more for keeping tools usable than any specific brand choice.
