Choosing ceramic glazes & colors often comes down to one practical question: do you need a single defined glaze for a focused finish, or a color assortment for experimentation? AMACO PC-27 Tourmaline and the 12-color set answer those needs differently. This head-to-head separates the single-glaze route from the palette-led route so you can match the purchase to the kind of pottery project you have in mind.
Quick verdict
Choose AMACO PC-27 Tourmaline when the project centers on one named glaze and a defined finish. Choose 12 Assorted Colors of Non-Toxic Glazes when variety matters more and you want a palette for different visual directions. Neither answers the same shopping need: one is a focused glaze purchase, while the other is an assortment designed for broader color work.

Where each wins
AMACO PC-27 Tourmaline

AMACO wins when you want a single defined finish. The PC-27 Tourmaline name identifies the color, while the glossy stoneware glaze and brush-on format suit a focused application plan. At $18.00 versus $79.99 for the set, the absolute listed-price spread is $61.99. That makes AMACO the direct match when the project needs one named glaze rather than a palette.
12 Assorted Colors of Non-Toxic Glazes

The 12-color set wins when color variety is the deciding factor. Its Cone 06/05 specification and stated ability to be used at higher cone temperatures give it a clear place in projects planned around those firing details. The assortment is also a natural fit for palette exploration, especially when the finished work may call for several different color directions.
Product notes
AMACO PC-27 Tourmaline Glaze
AMACO PC-27 Tourmaline Glaze suits a project organized around a named color rather than a broad assortment. It is identified as lead-free, and its 1-pint format gives you a single container dedicated to the Tourmaline glaze. That is a concrete reason to choose it when you already know the glaze color you want. The limitation is range: the purchase is centered on Tourmaline, so it does not provide the palette breadth of the 12 Assorted Colors set. It is less aligned with a shopper whose goal is sampling many shades in one purchase. For a focused pottery piece, the single-glaze format keeps the choice specific without adding colors that are not part of the plan.
12 Assorted Colors of Non-Toxic Glazes
12 Assorted Colors of Non-Toxic Glazes is the palette-led choice. The set contains 12 assorted colors in 4 oz containers, with semi-opaque and opaque formulas. It is also identified as lead-free and non-toxic, and the colors can be used individually, combined, or as accent highlights. Those details make it a concrete choice for varied pottery glaze colors and projects that call for more than one visual direction. The limitation is the divided-container format: each shade arrives in its own 4 oz container, so it is less aligned with a project requiring one named glaze in a single container. Choose it when color range and flexible application matter more than a single-color brief.
Final choice by use case
- Choose AMACO PC-27 Tourmaline for a focused project built around one named glaze, a glossy stoneware finish, and brush-on layering.
- Choose 12 Assorted Colors of Non-Toxic Glazes for palette exploration, multiple color directions, and Cone 06/05 planning.
- If the project brief is already centered on Tourmaline, AMACO is the more direct match. If the brief calls for assorted pottery glaze colors, the 12-color set fits that use case more closely.
