Valuation of possibility of the silicon based preparations application for strengthening Lublin-type mouldings

At the beginning of XVII-th Century in Little Poland region, flat, geometric decorations were common. Their came from North Germany and appeared in individual types, characteristic for particular regions. Typical variants of decorations were described by J. Szablowski with underlined net (typical for Lublin region), ferrule and geometrical decorations (typical for Cracow region). Cracovian-type decoration resembled West-European decorations and Lublin-Calisia-type were made by local bricklayers, which is hard to be proven, because of the foreign prototypes visible in many Lublin decorations. Article presents valuation of the silicon based preparations application possibility for strengthening Lublin-type mouldings. Valuated preparations differ in compounds. They are applied for conservatory works to strengthen such materials like calcium plasters and mouldings.
