Pastel Serum is a soft, lighting-reactive borosilicate colour from Glass Alchemy’s pastel CFL family. Learn how to work it in a neutral flame, avoid overheating thin applications, and use it effectively in blowouts, overlays, sculptural accents, and encased designs.

Amber Purple becomes far more controllable when you treat each layer as part of an optical system. This guide explains how Star White, Yellow, Orange, Violet, Lavender, clear caps, flame striking, and kiln striking affect the final result.

Amber Purple glass continues to develop even after the torch is turned off. In this post, we explore how cooling and annealing affect colour stability, clarity, and depth, and why proper temperature control in the kiln is just as important as heat cycles at the bench. Understanding this phase helps prevent dulling, preserve colour, and bring out the full potential of Amber Purple glass.

Amber Purple is a striking borosilicate colour that responds directly to heat cycles, flame atmosphere, and timing at the torch. In this post, we explore how Amber Purple develops during repeated heating and cooling, why neutral and oxidizing flames produce cleaner results, and how rotational speed affects silver haze and colour clarity. This guide is written for glass artists looking to gain better control over Amber Purple and reduce common issues like greying, muddiness, and uneven strikes.

Amber Purple is one of the most talked-about borosilicate colours, and one of the most misunderstood. Known for its shifting purples, blues, and ambers, it behaves very differently from standard transparent colours. In this first post of the series, we look at where Amber Purple comes from, how silver chemistry influences its behaviour, and why patience and heat control matter more than force. This post sets the foundation for understanding how Amber Purple develops at the torch and what it needs to reach its full potential.
