Scholz Ag

What Scholz Ag does

Scholz AG is a third-generation, family-owned Swiss art glass studio and glass painting workshop (Kunstglaserei/Glasmalerei) founded in 1965 by Fritz Scholz and Alfred Soratroi, headquartered at Bahnhofstrasse 27 in Rümlang near Zürich. The company specializes in the restoration, conservation, and new fabrication of stained glass (Glasmalerei), leaded glass (Bleiverglasung), brass glazing (Messingverglasung), and fused glass (Schmelzglas) for churches, public buildings, and private estates. Core technical capabilities span the full traditional craft stack — kiln-fired glass painting at approximately 600°C using Schwarzlot, silver-yellow (Silbergelb), and enamel techniques; complete in-house lead came fabrication from 1:1 Bleiriss drawings through cutting, assembly, soldering, and puttying; restoration following Corpus Vitrearum guidelines; and proprietary thermally separated, ventilated mounting systems that integrate heritage leaded glazing with modern insulating glass for energy retrofit of historic buildings. Supporting product lines include custom coat-of-arms panes (Wappenscheiben), sandblasted glass, memorial glass art (Grabmalkunst), and custom LED-illuminated art glass installations, manufactured in-house on 6cm-deep LED panels.

The business operates as a project-based professional services workshop serving German-speaking Switzerland (Deutschschweiz), with work sourced through cantonal and municipal heritage authorities (Denkmalpflege), architectural firms (e.g., Burch + Partner Architekten AG, Meierpartner, Spühler Partner), and direct inquiries. Pricing is quote-based per project, varying with scope, material complexity (notably mouth-blown antique glass from the company's multi-decade inventory of Restover, Tikana, Götheglas, Restauro, Tiffany, Dalles, and butzen/mond-scheiben), and heritage coordination requirements. Customer segments are concentrated in religious/heritage (churches, monasteries, chapels) and public/heritage buildings (Tonhalle Zürich, Synagogue Löwenstrasse, Schloss Hegi Winterthur), with secondary exposure to private villa restorations and select commercial/memorial commissions. The workshop team consists of approximately seven people, including the co-Managing Directors Patrick and Roger Scholz (third generation), senior craftsman and master trainer Dieter Scholz (second generation), two additional craftsmen/glass painters, and part-time administrative staff. Distribution is exclusively direct, with no resellers, marketplaces, or self-serve channels; an ongoing exhibition partnership with Umwelt Arena Spreitenbach (since 2015) provides top-of-funnel visibility.
