Which outcome arose when insufficient potash sources limited early Venetian Murano glass production?

💡 Explanation

Higher lead oxide proportions increased because, using 'fluxing', lower melting point increases workability with reduced potash availability. Therefore lead content rose, rather than temperature changes because impurities influence thermal stress resistance.
