Boar Bristles Vs Silicone: What Are The Differences Between These Pastry Brushes? - Tasting Table
Briefly

The primary distinction between boar bristle and silicone pastry brushes is their performance—how evenly they spread liquids, their ease of cleaning, and durability.
Boar bristle brushes are preferred for their soft yet firm bristles that hold more liquid and allow for smoother glaze application, thanks to their flagged tips.
Silicone pastry brushes, introduced in the 1960s, offer a different approach with larger flexible bristles that are colorful and typically easier to clean.
Choosing between a boar bristle and a silicone brush largely depends on personal preference for specific tasks, as both have their unique advantages.
